Abstract
A Gram-stain-positive aerobic, rod-shaped, spore-producing bacterium forming colonies with convex elevation and a smooth, intact margin was isolated from a freshwater sample collected from a well situated in an agricultural field. The 16S rRNA gene sequence of the isolated strain BA0131T showed the highest sequence similarity to Lysinibacillus yapensis ylb-03T (99.25%) followed by Ureibacillus chungkukjangi 2RL3-2T (98.91%) and U. sinduriensis BLB-1T (98.65%). The strain BA0131T was oxidase and catalase positive and urease negative. It also tested positive for esculin hydrolysis and reduction of potassium nitrate, unlike its phylogenetically closest relatives. The predominant fatty acids in strain BA0131T included were anteiso-C15:0, iso-C16:0, iso-C15:0, iso-C14:0 and the major polar lipids comprised were phosphatidylglycerol, diphosphatidylglycerol and phosphatidylethanolamine. The respiratory quinones identified in strain BA0131T were MK8 (H2) (major) and MK8 (minor). The strain BA0131T shared the lowest dDDH values with L. yapensis ylb-03T (21%) followed by U. chungkukjangi 2RL3-2T (24.2%) and U. sinduriensis BLB-1T (26.4%) suggesting a closer genetic relationship U. sinduriensis BLB-1T. The ANI percentage supported the close relatedness with U. sinduriensis BLB-1T (83.61%) followed by U. chungkukjangi 2RL3-2T (82.03%) and U. yapensis ylb-03T (79.57%). The core genome-based phylogeny constructed using over 13,704 amino acid positions and 92 core genes revealed the distinct phylogenetic position of strain BA0131T among the genus Ureibacillus. The distinct physiological, biochemical characteristics and genotypic relatedness data indicate the strain BA0131T represents a novel species of the genus Ureibacillus for which the name Ureibacillus aquaedulcis sp. nov. (Type strain, BA0131T = MCC 5284 = JCM 36475) is proposed. Additionally, based on extensive genomic and phylogenetic analyses, we propose reclassification of two species, L. yapensis and L. antri, as U. yapensis comb. nov. (Type strain, ylb-03T = JCM 32871T = MCCC 1A12698T) and U. antri (Type strain, SYSU K30002T = CGMCC 1.13504T = KCTC 33955T).

Abstract
Microbial fuel cells (MFCs) function by using microorganisms to decompose the substrate at the anode, producing electrons and protons. These charges are then transported to the cathode, where electricity is generated. Previous studies have shown their promising probabilities for practical applications. MFCs are praised for their ability to address energy shortages and environmental pollution simultaneously. They have the potential to generate electricity directly from organic substances, reducing energy losses that occur during intermediate conversion steps. The main challenge lies in transitioning these technologies from the laboratory setting to practical systems that can be implemented on a large scale for bioenergy production along with various engineering hurdles. This study focused on investigating the power production potential of a soil-isolated bacterial strain taxonomically classified as Lysinibacillus xylanilyticus nbpp1, which is a relatively new addition to the extensive range of biocatalysts known for their ability to generate electricity. The study analyzed the electrochemical performance of an H-type MFC setup. LB broth was used as the substrate, while aluminum and graphite served as electrode materials. Other parameters, such as Coulombic efficiency, internal resistance, and electrode corrosion rate, were also measured. The MFC produced a high open circuit voltage of 1127 mV and achieved a maximum power density of 6.71 mW/cm2 at a current density of 11.14 mA/cm2. The MFC setup successfully powered LED lamps when connected in a joint circuit, showcasing its potential for practical applications. These findings suggest the promising high electrochemical performance of the MFC system in terms of electricity generation using the specified conditions.

Abstract
A gram-staining-positive, rod-shaped bacterium, designed strain FJAT-51161T was isolated from farmland soil collected from Fujian Province, China. Growth was observed at 25-40 °C (optimum 30 °C), pH 7.0-9.0 (optimum 7.0), and NaCl tolerance in the range of 0-7% (w/v), respectively. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the strain FJAT-51161T belonged to the genus Lysinibacillus, and had the closest relationship with Lysinibacillus xylanilyticus XDB9T (99.0% 16S rRNA sequence similarity). The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values based on the genome sequence analysis between strain FJAT-51161T and the closest reference strain were 38.0% for dDDH and 88.7% for ANI, respectively, lower than the prokaryotic species delineation values. Further analysis showed that strain FJAT-51161T shared the fatty acid profiles such as iso-C15:0 (46.7%), iso-C16:0 (15.8%), C16:1 ω7c alcohol (14.0%), anteiso-C15:0 (6.9%) with other members of the genus Lysinibacillus. As the peptidoglycan contained the amino acids alanine, lysine, glycine and aspartic acid, the type A4α was deduced as found in the closest relatives of strain FJAT-51161T. The peptidoglycan of strain FJAT-51161T was L-Lys-D-Asp (type A4α). The main quinone was MK-7 and MK-6. The major polar lipids were diphosphatidylglycerol (DPG) and phosphatidylethanolamine (PE). The DNA G + C content is 36.6 mol%. Based on the phenotypic characters and taxono-genomics study, strain FJAT-51161T is considered to represent a novel Lysinibacillus species, for which the name Lysinibacillus agricola sp. nov. is proposed. The type strain is FJAT-51161T (GDMCC1.2350T = KCTC 43326T).

Robust Demarcation of the Family Caryophanaceae ( Planococcaceae) and Its Different Genera Including Three Novel Genera Based on Phylogenomics and Highly Specific Molecular Signatures. Front Microbiol 2020; 10:2821. [PMID: 32010063 PMCID: PMC6971209 DOI: 10.3389/fmicb.2019.02821] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Accepted: 11/20/2019] [Indexed: 12/12/2022] Open
Abstract
The family Caryophanaceae/Planococcaceae is a taxonomically heterogeneous assemblage of >100 species classified within 13 genera, many of which are polyphyletic. Exhibiting considerable phylogenetic overlap with other families, primarily Bacillaceae, the evolutionary history of this family, containing the potent mosquitocidal species Lysinibacillus sphaericus, remains incoherent. To develop a reliable phylogenetic and taxonomic framework for the family Caryophanaceae/Planococcaceae and its genera, we report comprehensive phylogenetic and comparative genomic analyses on 124 genome sequences from all available Caryophanaceae/Planococcaceae and representative Bacillaceae species. Phylogenetic trees were constructed based on multiple datasets of proteins including 819 core proteins for this group and 87 conserved Firmicutes proteins. Using the core proteins, pairwise average amino acid identity was also determined. In parallel, comparative analyses on protein sequences from these species have identified 92 unique molecular markers (synapomorphies) consisting of conserved signature indels that are specifically shared by either the entire family Caryophanaceae/Planococcaceae or different monophyletic clades present within this family, enabling their reliable demarcation in molecular terms. Based on multiple lines of investigations, 18 monophyletic clades can be reliably distinguished within the family Caryophanaceae/Planococcaceae based on their phylogenetic affinities and identified molecular signatures. Some of these clades are comprised of species from several polyphyletic genera within this family as well as other families. Based on our results, we are proposing the creation of three novel genera within the family Caryophanaceae/Planococcaceae, namely Metalysinibacillus gen. nov., Metasolibacillus gen. nov., and Metaplanococcus gen. nov., as well as the transfer of 25 misclassified species from the families Caryophanaceae/Planococcaceae and Bacillaceae into these three genera and in Planococcus, Solibacillus, Sporosarcina, and Ureibacillus genera. These amendments establish a coherent taxonomy and evolutionary history for the family Caryophanaceae/Planococcaceae, and the described molecular markers provide novel means for diagnostic, genetic, and biochemical studies. Lastly, we are also proposing a consolidation of the family Planococcaceae within the emended family Caryophanaceae.

Abstract
A Gram-positive, aerobic, rod-shaped, spore-forming bacterium, designated YLB-03T, with peritrichous flagella was isolated from deep-sea sediment of the Yap Trench at a depth of 4435 m. The bacterium was found to be catalase-positive but oxidase-negative. Growth of this bacterium was observed at 15-50°C (optimum 37°C), pH 5-10.5 (optimum 7), 0-5% NaCl (optimum 1%, w/v) and 0.1-50 MPa (optimum 0.1 MPa). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YLB-03T was a member of the genus Lysinibacillus. Strain YLB-03T was closely related to Lysinibacillus sinduriensis BLB-1T and Lysinibacillus chungkukjangi 2RL3-2T (98.4%), Lysinibacillus halotolerans LAM-612T (98.0%), Lysinibacillus telephonicus KT735049T (97.5%), Lysinibacillus endophyticus C9T (97.5%), Lysinibacillus composti NCCP-36T and Lysinibacillus massiliensis 4400831T (97.3%). The ANI and the GGDC DNA-DNA hybridization estimate values between strain YLB-03T and closely related type strains were 73.7-76.3% and 34.7-38.7%, respectively. The principal fatty acids were anteiso-C15:0 and iso-C15:0. The G+C content of the chromosomal DNA was 39.6 mol%. The respiratory quinone was determined to be MK-7. The diagnostic amino acids in the cell wall peptidoglycan contained Lys-Asp (type A4α) and the cell-wall sugars were glucose and xylose. The polar lipids included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, and an unidentified phospholipid. The combined genotypic and phenotypic data showed that strain YLB-03T represents a novel species within the genus Lysinibacillus, for which the name Lysinibacillus yapensis sp. nov. is proposed, with the type strain YLB-03T (= MCCC 1A12698T = JCM 32871T).

Abstract
A novel bacterial strain, designated S5H2222T, was isolated form the screen of a cellular phone. The cells were Gram-stain-positive, rod-shaped, aerobic and motile, and endospores are formed. S5H2222T grew as pale white colonies on trypticase soy agar and the best growth was observed at 37 °C (10-55 °C) and at pH 7.0 (5.0-9.0). S5H2222T could tolerate up to 10 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences placed this strain within the genus Lysinibacillus and it exhibited high 16S rRNA gene sequence similarity to Lysinibacillus halotolerans LAM612T (97.8 %), Lysinibacillus chungkukjangi 2RL3-2T (97.4 %) and Lysinibacillus sinduriensis BLB-1T (97.2 %). The DNA-DNA relatedness of the strain with L. halotolerans JCM 19611T, L. chungkukjangi KACC 16626T and L. sinduriensis KACC 16611T was 57, 64 and 55 % respectively. The genomic DNA G+C content was 39.8 mol%. The major fatty acids of S5H2222T were iso-C15 : 0, anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. MK-7 was the only menaquinone and the main polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine, four unidentified polar lipids were also present. The diagnostic amino acids in the cell wall peptidoglycan contained Lys-Asp (type A4α). On the basis of the results of the phenotypic and genotypic characterizations, it was concluded that S5H2222T represents a novel species of the genus Lysinibacillus, for which the name Lysinibacillus telephonicus sp. nov. is proposed. The type strain is S5H2222T (=MCC 3065T=KACC 18714T=LMG 29294T).
