title: Amphibacillus sediminis sp. nov., an endospore-forming bacterium isolated from lake sediment in Japan.
abstract: A facultatively anaerobic, moderately alkaliphilic, Gram-positive, spore-forming and rod-shaped bacterial strain, Shu-P-Ggiii25-2T, was isolated from lake sediment in Shizuoka, Japan, and was characterized taxonomically using a polyphasic approach. Analysis of the 16S rRNA gene sequence indicated that the novel isolate clustered with the type strain of Amphibacillus xylanus and it exhibited sequence similarities of 94.9-95.6% to the type strains of species of the genus Amphibacillus. Isoprenoid quinones and oxidase and catalase activities were not detected for strain Shu-P-Ggiii25-2T. The DNA G+C content was 42.3 mol%, the cell-wall peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid and the major cellular fatty acids were iso-C14:0, iso-C15:0, anteiso-C15:0, C16:0 and iso-C16:0. On the basis of phylogenetic position and phenotypic properties, strain Shu-P-Ggiii25-2T represents a novel species of the genus Amphibacillus, for which the name Amphibacillus sediminis sp. nov. is proposed. The type strain is Shu-P-Ggiii25-2T (=MBIC08269T=IAM 15428T=KCTC 13120T). An emended description of the genus Amphibacillus is also given.
