“…Some species have been reclassified in novel genera or transferred to other genera (Ash et al, 1993;Stackebrandt & Liesack, 1993;Shida et al, 1996;Wainø et al, 1999;Nazina et al, 2001;Yoon et al, 2001;Albert et al, 2007;Zhou et al, 2009). Many of these reclassifications are well supported by relatively conserved phenotypic traits such as the quinone system, peptidoglycan composition and polar lipid and cellular fatty acid profiles (Albert et al, 2007).…”

A Gram-stain-positive, spore-forming, rod-shaped and aerobic bacterium was isolated from a sediment sample from the South Sea in China. The isolate, designated H2 T , grew at 4-45 6C (optimum 37 6C) and pH 6-10 (optimum pH 7.0). The cell-wall peptidoglycan contained mesodiaminopimelic acid. The major isoprenoid quinone was MK-7 and the polar lipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and an unknown aminophospholipid. The major fatty acid was iso-C 15 : 0 . The genomic DNA G+C content of strain H2 T was 44.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate formed a monophyletic clade with Bacillus firmus IAM 12464 T . DNA-DNA relatedness between the isolate and B. firmus ATCC 14575 T was low (27.5 %). Strain H2 T also had a phenotypic profile that readily distinguished it from its closest phylogenetic neighbours. It is evident from the combination of genotypic and phenotypic data that the organism should be classified in a novel species of the genus Bacillus, for which the name Bacillus oceanisediminis sp. nov. is proposed. The type strain is H2 T (5CGMCC 1.10115 T 5JCM 16506 T ).The application of chemotaxonomic, numerical phenetic and molecular systematic methods has led to an improved description and a division of the genus Bacillus. Some species have been reclassified in novel genera or transferred to other genera (Ash et al., 1993;Stackebrandt & Liesack, 1993;Shida et al., 1996;Wainø et al., 1999;Nazina et al., 2001;Yoon et al., 2001;Albert et al., 2007;Zhou et al., 2009). Many of these reclassifications are well supported by relatively conserved phenotypic traits such as the quinone system, peptidoglycan composition and polar lipid and cellular fatty acid profiles (Albert et al., 2007). Falsibacillus is a newly described genus, which currently comprises a single species, Falsibacillus pallidus comb. nov., and is represented by the type strain, CW 7 T . The taxon F. pallidus comb. nov. is linked to the illegitimately named taxon Bacillus pallidus Zhou et al. 2008 and the creation of the genus Falsibacillus was primarily based on significant chemotaxonomic differences in comparison with the type species of the genus Bacillus, Bacillus subtilis (Zhou et al., , 2009). The genus Bacillus currently encompasses more than 150 species with validly published names and contains at least six phylogenetically distinct groups on the basis of molecular analyses of 16S rRNA gene sequences (Ash et al., 1991;Nielsen et al., 1994;Schlesner et al., 2001;Yoon et al., 2004;Carrasco et al., 2007). Members of the genus Bacillus have been isolated from a wide variety of aquatic and terrestrial environments. A Gram-stain-positive bacterium, strain H2 T , was isolated during an ecological survey of marine organisms in China and found to have morphological properties consistent with the genus Bacillus.Strain H2 T was isolated from a marine sediment collected at a depth of 823 m in the South Sea, China. A standard dilution-plating technique was used to ...

“…Innovations in the study of bacterial systematics have aided the reclassification of some bacilli into newly described genera or other related genera (Wisotzkey et al, 1992;Ash et al, 1993;Shida et al, 1996;Heyndrickx et al, 1998;Wainø et al, 1999;Yoon et al, 2001). The genus Virgibacillus was first proposed by Heyndrickx et al (1998) for Bacillus pantothenticus.…”

A Gram-variable, endospore-forming moderately halophilic rod, strain SF-121, was isolated from a marine solar saltern of the Yellow Sea in Korea. The result of 16S rRNA gene sequence analysis showed that strain SF-121 has highest sequence similarity (99?7 %) with the type strain of Bacillus halodenitrificans. Phylogenetic analyses based on 16S rRNA gene sequences revealed that B. halodenitrificans DSM 10037 T and strain SF-121 are more closely related to the genus Virgibacillus than to the genus Bacillus. Strain SF-121 and B. halodenitrificans DSM 10037 T exhibited 16S rRNA gene similarity levels of 95?3-97?5 % with the type strains of Virgibacillus species and 94?0 % with the type strain of Bacillus subtilis. DNA-DNA relatedness and phenotypic data indicated that B. halodenitrificans DSM 10037 T and strain SF-121 are members of the same species. B. halodenitrificans DSM 10037 T and strain SF-121 exhibited DNA-DNA relatedness values of 9-11 % with the type strains of Virgibacillus carmonensis and Virgibacillus marismortui. On the basis of the phenotypic, chemotaxonomic, phylogenetic and genetic data, B. halodenitrificans should be reclassified in the genus Virgibacillus as Virgibacillus halodenitrificans comb. nov.

“…The genus Bacillus is phylogenetically and phenotypically very heterogeneous (Claus & Berkeley, 1986) and in fact over the last decade nine new genera have been separated from this original taxon (Wisotzkey et al, 1992;Ash et al, 1993;Shida et al, 1996;Heyndrickx et al, 1998;Waino et al, 1999;Nazina et al, 2001;Yoon et al, 2001;Fortina et al, 2001). It is more than likely that future years will see a further reorganization of the genus.…”

Two Gram-positive, rod-shaped, endospore-forming bacteria (strains CR-119T and CR-95T) were isolated from brackish sediments in the mouth of the river Vélez in Málaga, southern Spain, and subjected to a polyphasic taxonomic study. Phenotypic tests showed that these strains were related to other Bacillus species at a similarity level of less than 87·6 %. Both strains are halotolerant, aerobic, chemoheterotrophic, motile with peritrichous flagella and biosurfactant producers. Their endospores are oval, subterminal and non-deforming structures. The predominant menaquinone in both strains is MK-7. The fatty-acid profiles of both strains contain large quantities of branched and saturated fatty acids. The major fatty acids (%) are 15 : 0 anteiso (32·4), 15 : 0 iso (16·8), 17 : 0 iso (13·4), 16 : 0 (11·5) and 17 : 0 anteiso (10·2) in strain CR-119T and 15 : 0 anteiso (37·5), 17 : 0 iso (16·0) and 17 : 0 anteiso (15·8) in strain CR-95T. The G+C contents of strains CR-119T and CR-95T are 41·0 and 42·5 mol%, respectively. RAPD analysis confirmed the low degree of similarity between the two strains and also amongst other Bacillus species. 16S rRNA gene analysis of strain CR-119T showed the highest sequence similarity to be 97·4 %, with Bacillus mojavensis and Bacillus subtilis subsp. spizizenii. In the case of strain CR-95T, the maximum similarity value was 99·5 %, with B. mojavensis. DNA–DNA hybridization of strains CR-119T and CR-95T with the above species produced values lower than 46·9 %. Therefore, on the basis of phenotypic characteristics, phylogenetic data and genomic distinctiveness, we conclude that these Bacillus strains merit classification as novel species, for which we propose the names Bacillus axarquiensis sp. nov. (type strain CR-119T=CECT 5688T=LMG 22476T) and Bacillus malacitensis sp. nov. (type strain CR-95T=CECT 5687T=LMG 22477T).
