Abstract

A facultatively anaerobic, moderately alkaliphilic, Gram-positive, spore-forming and rod-shaped bacterial strain, Shu-P-Ggiii25-2, 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 and it exhibited sequence similarities of 94.9–95.6 % to the type strains of species of the genus . Isoprenoid quinones and oxidase and catalase activities were not detected for strain Shu-P-Ggiii25-2. The DNA G+C content was 42.3 mol%, the cell-wall peptidoglycan contained -diaminopimelic acid as the diagnostic diamino acid and the major cellular fatty acids were iso-C, iso-C, anteiso-C, C and iso-C. On the basis of phylogenetic position and phenotypic properties, strain Shu-P-Ggiii25-2 represents a novel species of the genus for which the name sp. nov. is proposed. The type strain is Shu-P-Ggiii25-2 (=MBIC08269=IAM 15428=KCTC 13120). An emended description of the genus is also given.
