    ABSTRACT: A Gram-stain-positive, rod-shaped bacterium, designated strain NH3(T), was isolated from a sediment sample from the South China Sea and was subjected to a polyphasic taxonomic study. The isolate grew optimally at 37 °C and pH 9. Strain NH3(T) had cell-wall peptidoglycan based on meso-diaminopimelic acid and MK-7 as the predominant menaquinone. The cellular fatty acid profile included significant amounts of iso-C(15 : 0) and iso-C(14 : 0). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The DNA G+C content of strain NH3(T) was 40.3 mol%. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain NH3(T) was a member of rRNA group 6 of the genus Bacillus, which includes alkalitolerant, alkaliphilic and halotolerant species. The closest phylogenetic relatives were Bacillus akibai 1139(T) (96.82 % 16S rRNA gene sequence similarity), B. pseudofirmus DSM 8715(T) (96.76 %), B. okhensis Kh10-101(T) (96.76 %) and B. alkalidiazotrophicus MS 6(T) (96.47 %). Strain NH3(T) could be distinguished from these phylogenetically close neighbours based on a number of phenotypic properties. On the basis of phenotypic and chemotaxonomic characteristics and phylogenetic data, we conclude that strain NH3(T) ( = CGMCC 1.10116(T)  = JCM 16507(T)) merits classification as the type strain of a novel species, for which the name Bacillus nanhaiisediminis sp. nov. is proposed.

    ABSTRACT: 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 °C (optimum 37 °C) and pH 6-10 (optimum pH 7.0). The cell-wall peptidoglycan contained meso-diaminopimelic 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 44.8mol%. 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) (=CGMCC 1.10115(T) =JCM 16506(T)).

    ABSTRACT: A Gram-negative-staining bacterium, designated strain 25BT, was isolated from a soil sample from a rice field in Guangxi Province, China, and its taxonomic position was investigated by using a polyphasic approach. Cells were rod-shaped, non-spore-forming, non-motile and strictly aerobic. Strain 25BT grew optimally at 37 degrees C and pH 7.0. The predominant fatty acids of this soil isolate were C18:1omega7c, C19:0 cyclo omega8c and C16:0. Phylogenetic analysis based on the almost-complete 16S rRNA gene sequence showed that strain 25BT formed a monophyletic clade with the type strain of Microvirga subterranea; the two organisms shared 97.2% 16S rRNA gene sequence similarity. However, the two strains shared low DNA-DNA relatedness. Strain 25BT was also readily distinguishable from Microvirga subterranea DSM 14364T by various phenotypic characteristics. The combination of genotypic and phenotypic data suggests that the isolate represents a novel species of the genus Microvirga, for which the name Microvirga guangxiensis sp. nov. is proposed. The type strain is 25BT (=CGMCC 1.7666T=JCM 15710T).

    ABSTRACT: A polyphasic study was undertaken to establish the taxonomic status of a wheat-field soil isolate. The organism, strain 88T, was found to have a range of chemical and morphological properties consistent with its classification in the genus Saccharopolyspora. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence of the strain showed that it formed a monophyletic clade with the type strain of Saccharopolyspora spinosa. However, the two strains shared low DNA-DNA relatedness. Strain 88T also had a profile of phenotypic properties that readily distinguished it from representatives of the species of Saccharopolyspora with validly published names. It is evident from the combination of genotypic and phenotypic data that the organism should be classified within a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora shandongensis sp. nov. is proposed. The type strain is strain 88T (=CGMCC 4.3530T =JCM 14614T).
