| Popis: | A novel bacterial strain, designated S5T, was isolated from Pingaleshwar beach, in India. Cells were Gram-stain-positive, rod-shaped, non-motile and non-endospore-forming. Based on 16S rRNA gene sequence analysis, the strain was identified as belonging to the class Firmibacteria and was related most closely to Amphibacillus fermentum DSM 13869T (97.6 % sequence similarity). However, it shared only 93.1 % 16S rRNA gene sequence similarity with Amphibacillus xylanus NBRC 15112T, the type species of the genus, indicating that strain S5T might not be a member of the genus Amphibacillus. The DNA-DNA relatedness between strain S5T and Amphibacillus fermentum DSM 13869T was 39 %. The cell-wall peptidoglycan contained meso-diaminopimelic acid. Polar lipids included diphosphatidylglycerol, phosphatidylglycerol and two phospholipids. Isoprenoid quinones were absent from strain S5T. Fatty acid analysis revealed that anteiso-C15 : 0, C16 : 0 and iso-C15 : 0 were the predominant fatty acids present. The results of phylogenetic, chemotaxonomic and biochemical tests allowed the clear differentiation of strain S5T, which is considered to represent a novel species of a new genus in the family Bacillaceae, for which the name Pelagirhabdus alkalitolerans gen. nov., sp. nov. is proposed. The type strain of Pelagirhabdus alkalitolerans is S5T ( = KCTC 33632T = CGMCC 1.15177T). Based on the present study, it is also suggested to transfer Amphibacillus fermentum to this new genus, as Pelagirhabdus fermentum comb. nov. The type strain of Pelagirhabdus fermentum is Z-7984T = (DSM 13869T = UNIQEM 210T). |
