Abstract
A Gram-positive, cellulose-degrading actinobacterium, designed strain NEAU-YM18T, was isolated from rhizosphere soil of wheat (Triticum aestivum L.) sampled in Langfang, Hebei Province, PR China. The novel strain was characterized using a polyphasic approach. Morphological and chemotaxonomic characteristics confirmed that strain NEAU-YM18T belonged to the genus
Catellatospora
. Cells of strain NEAU-YM18T were observed to contain meso- and 3-hydroxy-diaminopimelic acids as diagnostic cell-wall amino acids. The acyl type of the cell-wall muramic acid was glycolyl. The whole-cell hydrolysates were xylose, glucose and ribose. The phospholipids consisted of diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The major fatty acids were iso-C15 : 0, iso-C16 : 0, C18 : 1
ω9c and summed feature 5 (anteiso-C18 : 0/C18 : 2
ω6,9c). The menaquinones were MK-9(H4), MK-9(H6) and MK-9(H2). The DNA G+C content was 71.1 %. The results of 16S rRNA gene sequence and phylogenetic analyses indicated that strain NEAU-YM18T was closely related to
Catellatospora chokoriensis
2-25(1)T (98.4 % 16S rRNA gene sequence similarity),
Catellatospora vulcania
NEAU-JM1T (98.3%) and
Catellatospora sichuanensis
H14505T (98.3 %) and formed a branch with
C. sichuanensis
H14505T. Furthermore, the whole genome phylogeny of strain NEAU-YM18T showed that the strain formed an independent clade. The digital DNA–DNA hybridization results between NEAU-YM18T and
C. chokoriensis
2-25(1)T,
C. vulcania
NEAU-JM1T and
C. sichuanensis
H14505T were 25.0, 24.7 and 24.7 %, respectively, and the whole-genome average nucleotide identity values between them were 81.5, 81.4 and 81.4 %, respectively. These genetic results and some phenotypic characteristics could distinguish strain NEAU-YM18T from its reference strains. In addition, genomic analysis confirmed that strain NEAU-YM18T had the potential to decompose cellulose and produce bioactive compounds. Therefore, strain NEAU-YM18T represents a novel species of the genus
Catellatospora
, for which the name Catellatospora tritici sp. nov. is proposed. The type strain is NEAU-YM18T (=CCTCC AA 2020040T=JCM 33977T).

Abstract
A novel actinobacterium, designated strain H14505T, was isolated from a soil sample collected in Hong Yuan, Sichuan, southwest PR China. The temperature, pH and NaCl ranges for growth were determined to be 15-35 °C (optimum, 28 °C), 6.0-8.0 (optimum, pH 7.0) and 0-2 % (w/v; optimum without NaCl), respectively. The polar lipdis detected for strain H14505T were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, glycolipid and four unidentified lipids. The predominant menaquinones of strain H14505T were MK-9(H4) and MK-9(H6), and the prevalent fatty acids (>10 %) were C18 : 1 ω9c, C17 : 1 ω8c, summed feature 5 (anteiso-C18 : 0/ C18 : 2 ω6,9c) and C16 : 0. Phylogenetic analysis based on 16S rRNA gene and whole-genome sequences indicated that strain H14505T showed high similarity to Catellatospora vulcania NEAU-JM1T (99.0 %) and Catellatospora paridis NEAU-CL2T (99.0 %), and formed a monophyletic clade within the the genus Catellatospora in the phylogenetic trees. However, the average nucleotide indentity and DNA-DNA hybridization values between strain H14505T and closely related Catellatospora species showed that it belonged to a distinct species. Furthermore, the results of morphological, physiological and biochemical tests allowed further phenotypic differentiation of strain H14505T from its closest relatives. Thus, it is proposed that strain H14505T represents a novel species of the genus Catellatospora, for which the name Catellatospora sichuanensis sp. nov. is proposed. The type strain of Catellatospora sichuanensis is H14505T (=JCM 32394T=CICC 11042T).

Abstract
An endophytic actinomycete, strain 3MP-10T, isolated from the root of Mimosa pudica was taxonomically studied based upon polyphasic approaches. This strain formed spiral spore chains on aerial mycelia. ll-Diaminopimelic acid, glucose and ribose were found in the whole-cell hydrolysates. It belonged to the genus
Streptomyces
and was closely related to
Streptomyces zhaozhouensis
DSM 42101T (98.9 %) and
Streptomyces sedi
JCM 16909T (98.6 %) based on 16S rRNA gene sequence analysis results. The major menaquinones were MK-10(H8), MK-10(H6) and MK-9(H8). The predominant cellular fatty acids were iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The detected phospholipids were diphosphatidylglycerol, phosphatidylinositol mannoside, phosphatidylinositol, phosphatidylethanolamine and phosphatidylglycerol. Strain 3MP-10T had a genome size of 7.2 Mb with a genome G+C content of 73.4 mol%. Results of in silico genome-based similarity analysis revealed ANIb values of 84.94 and 84.77 %, ANIm values of 88.01 and 87.92 %, and dDDH values of 29.9 and 29.6 % when compared with
S. zhaozhouensis
DSM 42101T and
S. sedi
JCM 16909T, respectively. Based on the polyphasic approach, digital DNA–DNA relatedness and average nucleotide identity, we propose that the novel actinomycete represents a novel species, Streptomyces mimosae, with type strain 3MP-10T (=JCM 33328T=TISTR 2646T).

Abstract
Rules 50a and 50b of the International Code of Nomenclature of Prokaryotes respectively regulate the elevation of a subspecies to the rank of a species and the lowering of a species to the rank of subspecies. The Code does not indicate that the resulting new names must be considered new combinations, as the cases described in Rules 50a and 50b are not covered by Rule 34a. Based on the rules of the Code, new combination events are applicable only at the identical rank, and therefore new combination events and new species/subspecies events are mutually exclusive. In spite of this there have been at least 44 cases in which the new names were described as comb. nov. during elevation in rank from subspecies to species and at least 30 such cases during lowering in rank from species to subspecies. To prevent confusion in the future we propose adding notes to Rules 50a and 50b to clarify the issue.

Abstract
Morphological variants in mycobacterial cultures under different growth conditions, including aging of the culture, have been shown to include fibrous aggregates, biofilms, coccoids, and spores. Here we discuss the diversity in shape and size changes demonstrated by bacterial cells with special reference to pleiomorphism observed in Mycobacterium spp. in response to nutritional and other environmental stresses. Inherent asymmetry in cell division and compartmentalization of cell interior under different growth conditions might contribute toward the observed pleiomorphism in mycobacteria. The regulatory genes comprising the bacterial signaling pathway responsible for initiating morphogenesis are speculated upon from bioinformatic identifications of genes for known sensors, kinases, and phosphatases existing in mycobacterial genomes as well as on the basis of what is known in other bacteria.

Abstract
An actinomycete strain, K12-0602T, was isolated from the root of a Helleborus orientalis plant in Japan. The 16S rRNA gene sequence of strain K12-0602T showed that it had a close relationship with members of the family
Micromonosporaceae
and the 16S rRNA gene sequence similarity values between strain K12-0602T and type strains of type species of 27 genera belonging to the family
Micromonosporaceae
were below 96.2 %. MK-9 (H4) and MK-9 (H6) were detected as major menaquinones, and galactose, xylose, mannose and ribose were present in the whole-cell hydrolysate. The acyl type of the peptidoglycan was glycolyl. Major fatty acids were iso-C15 : 0, iso-C16 : 0, C17 : 1ω9c and anteiso-C17 : 0. Phosphatidylethanolamine was detected as the phospholipid corresponding to phospholipid type II. The G+C content of the genomic DNA was 67 mol%. Analyses of the cell-wall peptidoglycan by TLC and LC/MS showed that it was composed of alanine, glycine, hydroxylglutamic acid and an unknown amino acid, which was subsequently determined to be 3,4-dihydroxydiaminopimelic acid using instrumental analyses, including NMR and mass spectrometry. On the basis of the phylogenetic analysis and chemotaxonomic characteristics, strain K12-0602T represents a novel species of a new genus in the family
Micromonosporaceae
, for which the name Rhizocola hellebori gen. nov., sp. nov. is proposed. The type strain of the type species is K12-0602T ( = NBRC 109834T = DSM 45988T). This is the first report, to our knowledge, of 3,4-dihydroxydiaminopimelic acid being found as a diamino acid in bacterial cell-wall peptidoglycan.

Abstract
Sediment samples collected off the coast of San Diego were analyzed for actinomycete diversity using culture-independent techniques. Eight new operational taxonomic units (OTUs) in the Streptomycetaceae were identified as well as new diversity within previously cultured marine OTUs. Sequences belonging to the marine actinomycete genus Salinispora were also detected, despite the fact that this genus has only been reported from more tropical environments. Independent analyses of marine sediments from the Canary Basin (3814 m) and the South Pacific Gyre (5126 and 5699 m) also revealed Salinispora sequences providing further support for the occurrence of this genus in deep-sea sediments. Efforts to culture Salinispora spp. from these samples have yet to be successful. This is the first report of Salinispora spp. from marine sediments > 1100 m and suggests that the distribution of this genus is broader than previously believed.

Abstract
A novel endophytic actinomycete, designated strain NEAU-J3(T), was isolated from soybean root (Glycine max (L.) Merr) and characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences suggested that strain NEAU-J3(T) fell within the family Micromonosporaceae. The strain was observed to form an extensively branched substrate mycelium, which carried non-motile oval spores with a smooth surface. The cell walls of strain NEAU-J3(T) were determined to contain meso-diaminopimelic acid and galactose, ribose and glucose were detected as whole-cell sugars. The major menaquinones were determined to be MK-9(H(4)) and MK-9(H(6)). The phospholipids detected were phosphatidylcholine and phosphatidylethanolamine. The major cellular fatty acids were determined to be C(16:0), C(18:1) ω9c, C(18:0), C(17:0), C(17:1) ω7c, anteiso-C(17:0), C(16:1) ω7c and C(15:0). The DNA G + C content was 62.5 mol%. On the basis of the morphological and chemotaxonomic characteristics, phylogenetic analysis and characteristic patterns of 16S rRNA gene signature nucleotides, strain NEAU-J3(T) is considered to represent a novel species of a new genus within the family Micromonosporaceae, for which the name Wangella harbinensis gen. nov., sp. nov. is proposed. The type strain of Wangella harbinensis is strain NEAU-J3(T) (=CGMCC 4.7039(T) = DSM 45747(T)).

Abstract
An actinomycete, designated FXJ1.102T, was isolated from acidic soil collected in Jiangxi Province, south-east China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FXJ1.102T belonged to the genus
Nonomuraea
and was most closely related to
Nonomuraea candida
HMC10T,
Nonomuraea turkmeniaca
DSM 43926T,
Nonomuraea antimicrobica
YIM 61105T and ‘Nonomuraea
aegyptia’ S136 (98.9, 98.3, 97.9 and 97.5 % 16S rRNA gene sequence similarities, respectively). The morphological characteristics were typical of the genus
Nonomuraea
. The chemotaxonomic properties, such as cell-wall chemotype IIIB, phospholipid type IV, MK-9(H4) as the major menaquinone and iso-C16 : 0 (22.2 %) as the major fatty acid, supported the assignment of the strain to the genus
Nonomuraea
. DNA–DNA relatedness and physiological tests allowed genotypic and phenotypic differentiation of strain FXJ1.102T from its closest phylogenetic relatives. The isolate therefore represents a novel species, for which the name Nonomuraea
jiangxiensis sp. nov. is proposed. The type strain is FXJ1.102T ( = CGMCC 4.6533T = NBRC 106679T).

Abstract
A novel endophytic actinomycete, strain YIM 65646T, was isolated from the roots of Artemisia annua L. collected from Yunnan Province, south-west China. Growth was observed in the temperature range 10–40 °C (optimum 20–28 °C) and at pH 6.0–9.0 (optimum pH 7.0). The organism formed well-developed, branched substrate mycelia, but aerial mycelium was not produced. Phenotypic characterization and 16S rRNA gene sequence analysis indicated that strain YIM 65646T belonged to the family Micromonosporaceae (sharing ≤93.6 % sequence similarity with members of this family) and formed a distinct clade in the Micromonosporaceae phylogenetic tree. The strain contained meso-diaminopimelic acid in the cell wall and mannose, ribose, galactose and glucose in whole-cell hydrolysates. The major menaquinones were MK-10(H4), MK-10(H2), MK-8(H2), MK-9(H2) and MK-10(H6). The major fatty acids were iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0, iso-C17 : 0 and iso-C16 : 0. The DNA G+C content of strain YIM 65646T was 70.0 mol%. On the basis of morphological and chemotaxonomic properties and phylogenetic analysis based on 16S rRNA gene sequence data, it is proposed that this strain should be classified in a novel genus and species, Phytomonospora endophytica gen. nov., sp. nov., in the family Micromonosporaceae. The type strain is YIM 65646T ( = CCTCC AA 209041T = DSM 45386T).

Abstract
A novel actinomycete, designated strain Sco-B14T, was isolated from volcanic ash collected near Darangshi Oreum (a parasitic or satellite volcano) in Jeju, Republic of Korea. The organism formed well-developed, branched substrate mycelium, on which short chains of non-motile spores were arranged singly or in clusters. Aerial mycelium was not produced. Globose bodies were observed. The reverse colour of colonies was light brown to brown. Diffusible pigments were produced on ISP medium 3 and oatmeal-nitrate agar. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Sco-B14T formed a lineage within the family Micromonosporaceae and was distinct from established genera. The 16S rRNA gene sequence similarity of strain Sco-B14T to members of related genera of the family was 95.0–95.7 % to type strains of Catellatospora species, 94.7 % to Hamadaea tsunoensis IMSNU 22005T, 94.7 % to Longispora albida K97-0003T and 94.0 % to Catelliglobosispora koreensis LM 042T. 3-Hydroxydiaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. Whole-cell sugars were glucose, rhamnose, ribose, xylose, arabinose, galactose and mannose. The polar lipids included diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The menaquinone profile contained MK-10(H4) (49 %), MK-9(H4) (24 %), MK-10(H6) (18 %) and MK-9(H6) (9 %). The predominant fatty acids were iso-C15 : 0 and C17 : 0. The DNA G+C content was 70.1 mol%. The combination of chemotaxonomic and phylogenetic data clearly separated the isolate from the type strains of all genera in the family Micromonosporaceae. On the basis of the phylogenetic and chemotaxonomic data presented in this paper, strain Sco-B14T is considered to represent a novel species of a new genus in the family Micromonosporaceae, for which the name Allocatelliglobosispora scoriae gen. nov., sp. nov. is proposed. The type strain of Allocatelliglobosispora scoriae is Sco-B14T (=KCTC 19661T =DSM 45362T).

Abstract
An actinomycete strain, K07-0523T, was isolated from the roots of an orchid collected in Okinawa prefecture, Japan. 16S rRNA gene sequence analysis indicated that the new strain belonged to the family Micromonosporaceae and the similarity values between strain K07-0523T and the type species of 24 genera in the family Micromonosporaceae were 93.3–97.7 %. Strain K07-0523T contained d-glutamic acid, glycine, d-alanine, meso-diaminopimelic acid, hydroxydiaminopimelic acid and l-lysine in the cell wall. The major menaquinones were MK-9(H6), MK-10(H4) and MK-10(H6). Galactose, glucose, mannose, ribose and xylose were present in the whole-cell sugars. The acyl type of the peptidoglycan was glycolyl. Major fatty acids were anteiso-C17 : 0, iso-C17 : 0, iso-C16 : 0 and iso-C15 : 0. Phosphatidylethanolamine was detected as the major phospholipid and corresponded to phospholipid type II. The G+C content of the genomic DNA was 73 mol%. On the basis of phylogenetic and chemotaxonomic data, the new strain represents a member of a new genus and novel species, namely Phytohabitans suffuscus gen. nov., sp. nov., in the family Micromonosporaceae. The type strain of the type species is K07-0523T (=DSM 45306T=NBRC 105367T).

Abstract
A novel endophytic actinomycete, designated strain 202201(T), was isolated from an Acanthus illicifolius root collected from the mangrove reserve zone in Hainan Province, China. Phylogenetic analysis based on 16S rRNA gene sequences suggested that strain 202201(T) fell within the family Micromonosporaceae. The strain formed an extensively branched substrate mycelium, which carried uneven warty-surfaced spores. Cell walls of strain 202201(T) contained meso-diaminopimelic acid and xylose, mannose, arabinose, ribose and glucose were detected as whole-cell sugars. The acyl type of the cell-wall polysaccharides was glycolyl. The major menaquinones were MK-9(H(4)), MK-9(H(6)), MK-9(H(8)) and MK-10(H(4)). The polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol mannoside and phosphatidylserine. The major cellular fatty acids were 10-methyl-C(17 : 0), iso-C(15 : 0), iso-C(16 : 0) and C(17 : 1)ω8c. The DNA G+C content was 72.3 mol%. On the basis of the morphological and chemotaxonomic characteristics, phylogenetic analysis and characteristic patterns of 16S rRNA gene signature nucleotides, strain 202201(T) ( = CGMCC 4.5597(T ) = DSM 45430(T)) represents a novel species of a new genus within the family Micromonosporaceae, for which the name Jishengella endophytica gen. nov., sp. nov. is proposed.

Abstract
Bacteria have the ability to adapt to different growth conditions and to survive in various environments. They have also the capacity to enter into dormant states and some bacteria form spores when exposed to stresses such as starvation and oxygen deprivation. Sporulation has been demonstrated in a number of different bacteria but Mycobacterium spp. have been considered to be non-sporulating bacteria. We recently provided evidence that Mycobacterium marinum and likely also Mycobacterium bovis bacillus Calmette–Guérin can form spores. Mycobacterial spores were detected in old cultures and our findings suggest that sporulation might be an adaptation of lifestyle for mycobacteria under stress. Here we will discuss our current understanding of growth, cell division, and sporulation in mycobacteria.

Abstract
Two actinomycete strains, CM2-8(T) and CM2-12, were isolated from temperate peat swamp forest soil in Chiang Mai Province, Thailand. Their taxonomic positions were determined using a polyphasic approach. Chemotaxonomic characteristics of these strains coincided with those of the family Micromonosporaceae, i.e. cell wall chemotype II, N-glycolyl type of muramic acid, and type II phospholipids. Phylogenetic analysis based on 16S rRNA gene sequence data also indicated that these strains fell within the family Micromonosporaceae and formed a distinct taxon in the Micromonosporaceae phylogenetic tree. On the basis of phylogenetic analysis, characteristic patterns of 16S rRNA gene signature nucleotides and chemotaxonomic data, it is proposed that the novel isolates belong to a new genus, Actinaurispora gen. nov. The type species of the genus is proposed as Actinaurispora siamensis sp. nov., with strain CM2-8(T) (=JCM 15677(T)=BCC 34762(T)) as the type strain.

Abstract
A novel Gram-positive, aerobic, spore-forming, endophytic actinomycete, designated strain YIM 61359(T), was isolated from the roots of Maytenus austroyunnanensis plants collected from tropical rainforest in Xishuangbanna, Yunnan Province, south-west China. The strain formed single or cluster spores with smooth surfaces from substrate mycelia. The strain contained meso-diaminopimelic acid in the cell wall and arabinose, xylose, galactose and glucose in whole-cell hydrolysates. The acyl type of the cell-wall polysaccharides was glycolyl. MK-10(H(6)), MK-10(H(8)) and MK-10(H(4)) were the predominant menaquinones. The polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol and several unknown phospholipids. The major fatty acids were iso-C(15 : 0), anteiso-C(15 : 0), C(17 : 0), anteiso-C(17 : 0) and iso-C(16 : 0). The DNA G+C content of strain YIM 61359(T) was 69.7 mol%. These chemotaxonomic data indicated that the strain belongs to the family Micromonosporaceae. Phylogenetic analysis based on 16S rRNA gene sequences also suggested that strain YIM 61359(T) fell within the family Micromonosporaceae. On the basis of morphological and chemotaxonomic data, phylogenetic analysis and characteristic patterns of 16S rRNA gene signature nucleotides, strain YIM 61359(T) is considered to represent a novel species of a new genus within the family Micromonosporaceae, for which the name Plantactinospora mayteni gen. nov., sp. nov. is proposed.

Abstract
An actinomycete strain 3-44-a(19)(T) was isolated from sandy soil collected in Bangladesh. The strain formed irregular pseudosporangia directly from aggregated spore chains above the rudimentary aerial mycelium. The pseudosporangia developed singly. Each pseudosporangium contained many small, non-motile, spherical, smooth-surfaced spores in chains. Strain 3-44-a(19)(T) contained meso- and 3-hydroxydiaminopimelic acid in the cell wall and MK-9(H(6)) as the major menaquinone and arabinose, galactose, glucose, mannose, ribose and xylose were present in the whole-cell hydrolysate. The diagnostic phospholipid was phosphatidylethanolamine and iso-C(15 : 0) (24.6 %), C(18 : 1)omega9c (15.5 %), C(16 : 0) (10.6 %), C(18 : 0) (9.4 %), iso-C(16 : 0) (8.6 %) and anteiso-C(15 : 0) (6.0 %) were detected as the major cellular fatty acids. The acyl type of the peptidoglycan was glycolyl and mycolic acids were not detected. The G+C content of the DNA was 73.6 mol%. The chemotaxonomic data indicated that the strain belonged to the family Micromonosporaceae. Phylogenetic analysis based on 16S rRNA gene sequence data also suggested that strain 3-44-a(19)(T) fell within the family Micromonosporaceae. On the basis of phylogenetic analysis and characteristic patterns of 16S rRNA gene signature nucleotides as well as morphological and chemotaxonomic data, this strain should be classified as a member of a new genus and species, Pseudosporangium ferrugineum gen. nov., sp. nov., in the family Micromonosporaceae. The type strain of Pseudosporangium ferrugineum is 3-44-a(19)(T) (=JCM 14710(T) =MTCC9007(T)).

Abstract
A strain of Nonomuraea was isolated from Maheshkhali, Cox's Bazar, an unexplored region of Bangladesh. Strain 16-5-14(T) is a Gram-positive, aerobic, non-motile actinomycete that formed branched substrate and aerial mycelia. On the basis of 16S rRNA gene sequence similarity studies, strain 16-5-14(T) was shown to belong to the genus Nonomuraea, being most closely related to Nonomuraea kuesteri. Chemotaxonomic data supported allocation of the strain as a member of the genus Nonomuraea. The strain 16-5-14(T) contained MK-9(H(4)) as the major menaquinone, the polar lipid was phosphatidylethanolamine and major cellular fatty acids were observed as C(16 : 0 )(15.5%), iso-C(16 : 0) (13.8%) and 10-methyl C(17 : 0) (9.6%). Results of DNA-DNA hybridization and physiological tests allowed genotypic and phenotypic differentiation of strain 16-5-14(T) from closely related species N. kuesteri. Thus 16-5-14(T) represents a novel species of the genus Nonomuraea. On the basis of evaluation of the morphological, physiological and chemotaxonomic characteristics, 16S rRNA gene sequence comparisons and DNA-DNA hybridization, Nonomuraea maheshkhaliensis sp. nov. (type strain, 16-5-14(T)=JCM 13929(T)=MTCC 8545(T)) is proposed.

Abstract
Two novel bacterial strains were isolated from sandy soil from Cox's Bazar, Bangladesh. Strains 5-10-10(T) and 5-38-42(T) were Gram-positive, aerobic, non-motile actinomycetes that form branched substrate and aerial mycelium. On the basis of 16S rRNA gene sequence similarity studies, the novel strains were shown to belong to the genus Nonomuraea, being most closely related to Nonomuraea fastidiosa. Chemotaxonomic data supported the assignment of the novel strains as members of the genus Nonomuraea. Strain 5-10-10(T) contained MK-9(H(4)) and strain 5-38-42(T) contained MK-9(H(6)) and MK-9(H(4)) as the major menaquinones. Major polar lipids were phosphatidylethanolamine and hydroxyphosphatidylethanolamine. The major cellular fatty acid for strain 5-10-10(T) was iso-C(16 : 0) (26.4 %); C(16 : 0) (17.4 %) was the major cellular fatty acid for strain 5-38-42(T). The results of DNA-DNA hybridization and physiological tests enabled strains 5-10-10(T) and 5-38-42(T) to be differentiated genotypically and phenotypically from each other and from the closely related species, N. fastidiosa. On the basis of these results, strains 5-10-10(T) and 5-38-42(T) represent two novel species of the genus Nonomuraea. Following an evaluation of morphological, physiological and chemotaxonomic characteristics, 16S rRNA gene sequence comparisons and DNA-DNA hybridization experiments, the new isolates are proposed as two novel species, Nonomuraea bangladeshensis sp. nov. [type strain, 5-10-10(T) (=MTCC 8089(T)=JCM 13930(T))] and Nonomuraea coxensis sp. nov. [type strain, 5-38-42(T) (=MTCC 8090(T)=JCM 13931(T))].

Abstract
Three actinomycete strains were isolated from soil samples collected in Bangladesh. The cultures formed spherical sporangia on short sporangiophores directly above the surface of the substrate mycelium. The sporangia developed singly or in clusters and each sporangium contained several nonmotile spherical to oval spores with a smooth surface. The strains 3-9(24)(T), 3-21(27) and 7-40(26)(T) contained meso-diaminopimelic acid in the cell walls, predominant menaquinone MK-9(H(6)) and MK-9(H(4)) and glucose, xylose, galactose, mannose, rhamnose, ribose and arabinose in the whole-cell hydrolysates. Diagnostic phospholipid is phosphatidylethanolamine and branched anteiso-C(17 : 0) (30.0-38.0%), anteiso-C(15 : 0) (12.5-14.0%), iso-C(16 : 0) (10.0-15.0%) and iso-C(15 : 0) (10.0-12.0%) were detected as the major cellular fatty acids. The acyl type of the peptidoglycan was glycolyl and mycolic acids were not detected. The G+C content of the DNA was 71 mol%. The chemotaxonomic data indicate that these strains belong to the family Micromonosporaceae. Phylogenetic analysis based on 16S rRNA gene sequence data suggested that the strains 3-9(24)(T), 3-21(27) and 7-40(26)(T) fall within the family Micromonosporaceae. On the basis of phylogenetic analysis and characteristic patterns of signature nucleotides as well as morphological and chemotaxonomic data, Luedemannella gen. nov. is proposed for our 3 isolates. DNA-DNA hybridization experiment and phenotypic characterization indicated that the new genus was constituted of 2 species, as Luedemannella helvata sp. nov. for the strain 3-9(24)(T) (=JCM 13249(T)=MTCC 8091(T)) and Luedemannella flava for the strain 7-40(26)(T) (=JCM 13250(T)=MTCC 8095(T)) in the family Micromonosporaceae.

Abstract
Two actinomycete strains, 2-19(6)(T) and 2-30-b(28)(T), which produced single, non-motile noduler to warty spore surfaces, were isolated from sandy soil in Chokoria, Cox's Bazar, Bangladesh. A polyphasic study was carried out to establish the taxonomic position of these strains. Morphological and chemotaxonomic characteristics of these strains coincided with those of the genus Micromonospora. Phylogenetic analysis using 16S rDNA sequences indicated that these strains should be classified in the genus Micromonospora. The 16S rDNA sequence of strain 2-19(6)(T )showed closest similarity to the type strains of M. mirobrigensis (98.9%) and M. carbonacea (98.8%), and the strain 2-30-b(28)(T) to the type strains of M. purpureochromogenes (99.4%), M. halophytica (99.3%) and M. aurantiaca (99.2%). Furthermore, a combination of DNA-DNA hybridization results and some differential physiological and biochemical properties indicated that these strains were distinguished from the phylogenetically closest relatives. These strains therefore represent two novel species, for which the name Micromonospora chokoriensis sp. nov. and Micromonospora coxensis sp. nov. are proposed. The type strains are 2-19(6)(T) (=JCM 13247(T) =MTCC 8535(T)) and 2-30-b(28)(T) (=JCM 13248(T)=MTCC 8093(T)).
