Abstract
Three moderately halophilic, spore-forming strains, designated BH030062T, BH030049 and BH030080, were isolated from a solar saltern in Korea. Phylogenetic analyses and comparative 16S rRNA gene sequence studies revealed that the isolates represent a novel distinct monophyletic lineage within the phyletic group classically defined as the genus Bacillus and are most closely related to members of the genera Gracilibacillus (93.7-95.1% similarity), Virgibacillus (93.5-94.8%), Halobacillus (94.8-95.9%), Filobacillus (94.4-94.8%) and Lentibacillus (93.3-93.7%). Strain BH030062T was strictly aerobic, rod-shaped, Gram-positive and motile by means of peritrichous flagella. It grew in the presence of 1-15% (w/v) NaCl and at temperatures of 15-45°C. The cell wall peptidoglycan contained A1γ -meso-diaminopimelic acid as the diagnostic diamino acid. The predominant cellular fatty acids were iso-C15:0, anteiso-C15:0 and iso-C16:0. DNA G+C content was about 41 mol% and the major isoprenoid quinone was MK-7. On the basis of their physiological and molecular properties, the isolates represent a new genus, Pontibacillus gen. nov., and novel species, Pontibacillus chungwhensis sp. nov. The type strain is BH030062T (= KCTC 3890T=DSM 16287T).
