Abstract
Strain F3212T, Gram-stain-negative, aerobic, helical and motile bacterium, was isolated from the marine sediment collected in a sea cucumber culture pond located in Rongcheng, China. Strain F3212T grew optimally at pH 8.5, at 30 °C and in the presence of 3.0 % (w/v) NaCl. Phylogenetic analysis, based on 16S rRNA gene sequences, indicated that strain F3212T belongs to the genus Marinospirillum, clustering with M. celere, M. alkaliphilum, M. minutulum, M. megaterium and M. insulare (with 96.4, 94.6, 93.1, 92.4 and 92.1 % 16S rRNA gene sequence similarities, respectively). The chemotaxonomic properties of strain F3212T were similar to those of members of the genus Marinospirillum. Q-8 was the sole respiratory ubiquinone and the genomic DNA G+C content was 53.3 mol%. The major fatty acids were C18 : 1 ω9c, C16 : 0 and C18 : 0. The polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unidentifed lipid and an unidentified aminophospholipid. The average nucleotide identity scores for strains M. celere DSM 18438T and M. minutulum DSM 6287T were 74.5 and 69.4 %, respectively. The DNA-DNA homologies with M. celere DSM 18438T and M. minutulum DSM 6287T were less than 20 %. It's concluded that strain F3212T represents a new species of the genus Marinospirillum, for which the name Marinospirillum perlucidum sp. nov. is proposed. The type strain is F3212T (=KCTC 52892T=MCCC 1H00198T).

Abstract
A Gram-negative, helical bacterium designated PH27AT was cultivated from an anchialine pool on Pearl and Hermes Atoll, Northwestern Hawaiian Islands. The obligately halophilic strain was motile by bipolar tufts of flagella and grew optimally at pH 7, and microaerobically or aerobically. Closest neighbours based on 16S rRNA gene nucleotide sequence identity are Marinospirillum celere v1c_Sn-redT (93.31 %) and M. alkaliphilum Z4T (92.10 %) in the family Oceanospirillaceae, class Gammaproteobacteria. PH27AT is distinguished phenotypically from members of the genus Marinospirillum by its hydrolysis of gelatin, the absence of growth in media containing ≤ 1 % (w/v) NaCl and the ranges of temperature (12–40 °C) and pH (5–8) for growth. The major compound ubiquinone Q-9 distinguishes the quinone system of strain PH27AT from those in members of the genus Marinospirillum and other members of the Oceanospirillaceae, in which the major quinone is Q-8. Major polar lipids in PH27AT were phosphatidylethanolamine and phosphatidylglycerol, with moderate amounts of diphosphatidylglycerol and phosphatidylserine. Spermidine and cadaverine dominated the polyamine pattern; large proportions of cadaverine have not been reported in members of the genus Marinospirillum. Genotypic and chemotaxonomic data show that PH27AT does not belong in the genus Marinospirillum or other genera of the family Oceanospirillaceae or the Halomonadaceae. We propose a new genus, Terasakiispira gen. nov., be created to accommodate Terasakiispira papahanaumokuakeensis gen. nov., sp. nov. as the type species, with PH27AT ( = ATCC BAA-995T = DSM 16455T = DSM 23961T) as the type strain.

Abstract
Thirteen strains of a novel spore-forming, Gram-positive, mesophilic heterotrophic bacterium were isolated from spacecraft surfaces (Mars Odyssey Orbiter) and assembly-facility surfaces at the Jet Propulsion Laboratory in California and the Kennedy Space Center in Florida. Phylogenetic analysis of 16S rRNA gene sequences has placed these novel isolates within the genus Bacillus, the greatest sequence similarity (99.9 %) being found with Bacillus pumilus. However, these isolates share a mere 91.2 % gyrB sequence similarity with Bacillus pumilus, rendering their 16S rRNA gene-derived relatedness suspect. Furthermore, DNA-DNA hybridization showed only 54-66 % DNA relatedness between the novel isolates and strains of B. pumilus. rep-PCR fingerprinting and previously reported matrix-assisted laser desorption/ionization time-of-flight mass spectrometry protein profiling clearly distinguished these isolates from B. pumilus. Phenotypic analyses also showed some differentiation between the two genotypic groups, although the fatty acid compositions were almost identical. The polyphasic taxonomic studies revealed distinct clustering of the tested strains into two distinct species. On the basis of phenotypic characteristics and the results of phylogenetic analyses of 16S rRNA and gyrB gene sequences, repetitive element primer-PCR fingerprinting and DNA-DNA hybridization, the 13 isolates represent a novel species of the genus Bacillus, for which the name Bacillus safensis sp. nov. is proposed. The type strain is FO-36b(T) (=ATCC BAA-1126(T)=NBRC 100820(T)).

Abstract
Two moderately halotolerant Gram-negative bacteria were isolated from tidal flat sediment of the South Sea in Korea (the Korea Strait). The strains, designated M9T and M18T, were strictly aerobic, rod-shaped and non-spore-forming and motile with a flagellum and their major fatty acids were C(16:0) and C(19:0) cyclo omega8c. Strains M9T and M18T could grow in the presence of up to 13-15% (w/v) NaCl, but their optimum salt concentrations were relatively low (0-3%, w/v). The major predominant isoprenoid quinone was Q-8 and the G + C content of the genomic DNA was 57-58 mol%. Phylogenetic analyses and comparative 16S rRNA gene sequence studies revealed that strains M9T and M18T formed a phylogenetic lineage distinct from the genus Teredinibacter within the class Gammaproteobacteria and were most closely related to the genera Microbulbifer, Saccharophagus and Teredinibacter, with less than 92.5% 16S rRNA gene sequence similarity. The level of 16S rRNA gene sequence similarity between the two strains was 96.7%. On the basis of physiological and phylogenetic properties, strains M9T and M18T represent separate species within a novel genus of the class Gammaproteobacteria, for which the names Marinimicrobium koreense gen. nov., sp. nov. (type species) and Marinimicrobium agarilyticum sp. nov. are proposed. The type strains of Marinimicrobium koreense and Marinimicrobium agarilyticum are M9T (= KCTC 12356T = DSM 16974T) and M18T (= KCTC 12357T = DSM 16975T), respectively.
