Abstract
An alkali, salt, and thermo-tolerant strain designated FJAT-45399T was isolated from marine sediment in Fujian Province, China. Strain FJAT-45399T was Gram-stain-positive, rod-shaped, and facultatively aerobic. It shared high 16S rRNA gene sequence similarities with the members of the genus Shouchella. Further, the phylogenetic and phylogenomic analysis also suggested strain FJAT-45399T clustered with the members of the genus Shouchella. Growth of strain FJAT-45399T was observed at 15-55 °C (optimum 45-50 °C), pH 7.0-13.0 (optimum 9.0) and 0-15% (w/v) NaCl (optimum 2%). It contained MK-7 as the menaquinone. The polar lipids were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG) and an unidentified glycolipid (UGL) and lipid (UL). The major fatty acids (> 10%) were C16:0 (22.8%), iso-C15:0 (21.3%), and anteiso-C15:0 (14.0%). The genomic DNA G + C content was 44.5%. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between strain FJAT-45399T and the most closely related type strain Shouchella clausii DSM 8716T (ANI 94.1% and dDDH 55.4%) were both below the cut-off level for species delineation. Based on the above results, strain FJAT-45399T represents a novel species of the genus Shouchella, for which the name Shouchella tritolerans sp. nov., is proposed. The type strain is FJAT-45399T (= GDMCC 1.3098T = JCM 35613T).

Abstract
A Gram-stain positive, long, rod-shaped, motile, and spore-forming bacterium (MEB199T) was isolated from a sediment sample collected from Lonar Lake, India. The strain was oxidase and catalase positive. The strain grew optimally at pH 10, NaCl concentration of 3.5% at 37°C. The major fatty acids were iso-C15:0, iso-C16:0, anteiso-C15:0, and iso-C17:0. The peptidoglycan contained meso-diaminopimelic acid (meso-DAP). Phosphatidylethanolamine, diphosphatidylglycerol, and phosphatidylglycerol were the major polar lipids of MEB199T. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain MEB199T belonged to the family Bacillaceae and exhibited a distinctive position among the members of the genus Alkalihalobacillus (Ahb.). Strain MEB199T shared the highest 16S rRNA gene sequence similarity with Alkalihalobacillus alkalinitrilicus ANL-iso4T (98.36%), whereas with type species Ahb. alcalophilus DSM 485T, it is 94.91%, indicating that strain MEB199T is distinctly related to the genus Alkalihalobacillus. The G + C content of genomic DNA was 36.47 mol%. The digital DNA-DNA hybridization (dDDH) (23.6%) and average nucleotide identity (ANI) (81%) values between strain MEB199T and Ahb. alkalinitrilicus ANL-iso4T confirmed the novelty of this new species. The pairwise identity based on the 16S rRNA gene sequence between the species of genus Alkalihalobacillus ranges from 87.4 to 99.81% indicating the heterogeneity in the genus. The different phylogenetic analysis based on the genome showed that the members of the genus Alkalihalobacillus separated into eight distinct clades. The intra-clade average amino acid identity (AAI) and percentage of conserved proteins (POCP) range from 52 to 68% and 37 to 59%, respectively, which are interspersed on the intra-genera cutoff values; therefore, we reassess the taxonomy of genus Alkalihalobacillus. The phenotypic analysis also corroborated the differentiation between these clades. Based on the phylogenetic analysis, genomic indices, and phenotypic traits, we propose the reclassification of the genus Alkalihalobacillus into seven new genera for which the names Alkalihalobacterium gen. nov., Halalkalibacterium gen. nov., Halalkalibacter gen. nov., Shouchella gen. nov., Pseudalkalibacillus gen. nov., Alkalicoccobacillus gen. nov., and Alkalihalophilus gen. nov. are proposed and provide an emended description of Alkalihalobacillus sensu stricto. Also, we propose the Ahb. okuhidensis as a heterotypic synonym of Alkalihalobacillus halodurans. Based on the polyphasic taxonomic analysis, strain MEB199T represents a novel species of newly proposed genus for which the name Alkalihalobacterium elongatum gen. nov. sp. nov. is proposed. The type strain is MEB199T (= MCC 2982T, = JCM 33704T, = NBRC 114256T, = CGMCC 1.17254T).

Abstract
The genus Bacillus, harbouring 293 species/subspecies, constitutes a phylogenetically incoherent group. In the absence of reliable means for grouping known Bacillus species into distinct clades, restricting the placement of new species into this genus has proven difficult. To clarify the evolutionary relationships among Bacillus species, 352 available genome sequences from the family Bacillaceae were used to perform comprehensive phylogenomic and comparative genomic analyses. Four phylogenetic trees were reconstructed based on multiple datasets of proteins including 1172 core Bacillaceae proteins, 87 proteins conserved within the phylum Firmicutes, GyrA-GyrB-RpoB-RpoC proteins, and UvrD-PolA proteins. All trees exhibited nearly identical branching of Bacillus species and consistently displayed six novel monophyletic clades encompassing 5-23 Bacillus species (denoted as the Simplex, Firmus, Jeotgali, Niacini, Fastidiosus and Alcalophilus clades), interspersed with other Bacillaceae species. Species from these clades also generally grouped together in 16S rRNA gene trees. In parallel, our comparative genomic analyses of Bacillus species led to the identification of 36 molecular markers comprising conserved signature indels in protein sequences that are specifically shared by the species from these six observed clades, thus reliably demarcating these clades based on multiple molecular synapomorphies. Based on the strong evidence from multiple lines of investigations supporting the existence of these six distinct 'Bacillus' clades, we propose the transfer of species from these clades into six novel Bacillaceae genera viz. Peribacillus gen. nov., Cytobacillus gen. nov., Mesobacillus gen. nov., Neobacillus gen. nov., Metabacillus gen. nov. and Alkalihalobacillus gen. nov. These results represent an important step towards clarifying the phylogeny/taxonomy of the genus Bacillus.

Abstract
Two novel (14BT and 7B) Gram-stain-positive, rod-shaped, motile and endospore-forming bacterial strains were isolated from Lonar soda lake, India. Based on 16S rRNA gene sequence analysis, the strains 14BT and 7B were identified as belonging to the class Firmibacteria and were most closely related to Bacillus halodurans LMG 7121T (99.7 and 99.8%, respectively), Bacillus okuhidensis LMG 22468T (99.1 and 99.2%, respectively) and other members in the genus Bacillus (<97.0%). However, the DNA-DNA relatedness studies indicated that the strains 14BT and 7B were distantly related to B. halodurans LMG 7121T (49.1 ± 0.6 and 45.7 ± 0.6, respectively) and B. okuhidensis LMG 22468T (40.9 ± 0.9 and 42.1 ± 0.5, respectively). The high 16S rRNA gene sequence similarity (99.9%) and DNA-DNA relatedness (88 ± 9) indicated that strains 14BT and 7B were members of a single species. The strains grew optimally at a pH of 9.0-9.5 with 2-5% (w/v) NaCl and temperature of 37 °C. Strains 14BT and 7B were catalase positive and oxydase negative. The cell wall of strain 14BT contained meso-diaminopimelic acid as the diagnostic diamino acid. Polar lipids include diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), an unknown aminophospholipid (APL1) and three unknown lipids (L1-3). The predominant isoprenoid quinone is MK-7. anteiso-C15:0 (30.8%) was the predominant fatty acid, and significant proportions of iso-C15:0 (24.9%), iso-C16:0 (17.9%) and anteiso-C17:0 (12.3%) were also detected in strains 14BT and 7B. The DNA G+C content of strains 14BT and 7B was 41.6 and 41.3 mol%, respectively. The results of molecular, physiological and biochemical tests allowed a clear differentiation of strains 14BT and 7B from all other members of the genus Bacillus, for which the name Bacillus alcaliphilum sp. nov. is proposed. The type strain is 14BT (=KCTC 33777T = CGMCC 1.15474T).

Abstract
Phylogenetic analyses were performed for members of the family Chromatiaceae, signature nucleotides deduced and the genus Alishewanella transferred to Chromatiaceae. Phylogenetic analyses were executed for the genera Alishewanella, Arsukibacterium and Rheinheimera and the genus Rheinheimera is proposed to be split, with the creation of the Pararheinheimera gen. nov. Furthermore, the species Rheinheimera longhuensis, is transferred to the genus Alishewanella as Alishewanella longhuensis comb. nov. Besides, the genera Alishewanella and Rheinheimera are also emended. Strain LNK-7.1T was isolated from a water sample from the Lonar Lake, India. Cells were Gram-negative, motile rods, positive for catalase, oxidase, phosphatase, contained C16:0, C17:1ω8c, summed feature3 (C16:1ω6c and/or C16:1ω7c) and summed feature 8 (C18:1ω7c) as major fatty acids, PE and PG as the major lipids and Q-8 as the sole respiratory quinone. Phylogenetic analyses using NJ, ME, ML and Maximum parsimony, based on 16S rRNA gene sequences, identified Alishewanella tabrizica RCRI4T as the closely related species of strain LNK-7.1T with a 16S rRNA gene sequence similarity of 98.13%. The DNA-DNA similarity between LNK-7.1T and the closely related species (A. tabrizica) was only 12.0% and, therefore, strain LNK-7.1T was identified as a novel species of the genus Alishewanella with the proposed name Alishewanella alkalitolerans sp. nov. In addition phenotypic characteristics confirmed the species status to strain LNK-7.1T. The type strain of A. alkalitolerans is LNK-7.1T (LMG 29592T = KCTC 52279T), isolated from a water sample collected from the Lonar lake, India.

Cell-wall amino acids were l-alanine, d-alanine, d-glutamic acid and meso-diaminopimelic acid. The genomic DNA G+C content of strains JC247T and JC248 was 48.2 and 48.1 mol%, respectively. Both strains were closely related with mean DNA–DNA hybridization >90 %. 16S rRNA gene sequence analysis of both strains indicated that they are members of the genus Bacillus within the family Bacillaceae of the phylum Firmicutes. Both strains had a 16S rRNA gene sequence similarity of 96.93 % with Bacillus firmus NCIMB 9366T and < 96.92 % with other members of the genus Bacillus. Sequence similarity between strain JC247T and JC248 was 100 %. Distinct morphological, physiological and genotypic differences from previously described taxa support the classification of strains JC247T and JC248 as representatives of a novel species of the genus Bacillus, for which the name Bacillus

Abstract
The purpose of this announcement is to effect the valid publication of the following effectively published new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send three copies of the pertinent reprint or photocopies thereof, or an electronic copy of the published paper to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries. It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in the nomenclature of prokaryotes. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.

Abstract
Two Gram-stain-positive, diesel oil-degrading, solvent-tolerant, aerobic, endospore-forming, rod-shaped bacteria were isolated from a contaminated laboratory plate. Based on 16S rRNA gene sequence analysis, strains JC228T and JC279 were identified as belonging to the genus
Bacillus
within the family
Bacillaceae
of the phylum
Firmicutes
and were found to be most closely related to
Bacillus carboniphilus
JCM 9731T (98.1 % 16S rRNA gene sequence similarity) and shared <96.0 % 16S rRNA gene sequence similarity with other members of the genus
Bacillus
. The DNA–DNA hybridization value between the two strains was 88±2 %. Strain JC228T showed 23.4±1 % reassociation (based on DNA–DNA hybridization) with
B. carboniphilus
LMG 18001T. The DNA G+C content of strains JC228T and JC279 was 39 and 38.4 mol%, respectively. Both strains were positive for catalase and oxidase activities, and negative for hydrolysis of starch and Tween 80. Strains JC228T and JC279 grew chemoorganoheterotrophically with optimum growth at pH 7 (range pH 7–9.5) and 35 °C (range 25–40 °C). Diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified phospholipid (PL2) were the major polar lipids. Major cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0, iso-C17 : 0 and C16 : 0. Whole-cell hydrolysates contained l-alanine, d-alanine, d-glutamic acid and meso-diaminopimelic acid. Both strains utilized diesel oil as sole carbon and energy source. The results of physiological, biochemical, chemotaxonomic and molecular analyses allowed clear differentiation of strains JC228T and JC279 from their closest phylogenetic neighbours. Therefore strains JC228T and JC279 represent a novel species of the genus
Bacillus
, for which the name Bacillus oleivorans sp. nov. is proposed. The type strain is JC228T ( = LMG 28084T = CCTCC AB 2013353T).
