AbstractStrain LBB3T isolated from Bogoria soda lake in Kenya is an alkaliphilic, Gram-positive, strictly aerobic, non-motile, spore-forming bacterium. It was identified as a member of the genus Bacillus on the basis of phenotypic and phylogenetic analyses. The organism grows optimally at 37 °C and pH 10. The G+C content of the genomic DNA is 37·5 mol%. 16S rRNA gene sequence analysis showed 95 and 96 % sequence similarity with Bacillus pseudofirmus (DSM 8715T) and Bacillus alcalophilus (DSM 485T), respectively. Furthermore, DNA–DNA hybridization against these two Bacillus species showed 39·0 and 55·5 % similarity, respectively. Based on our observations, strain LBB3T is proposed to represent a novel species of the genus Bacillus, for which the name Bacillus bogoriensis sp. nov. is proposed. The type strain of B. bogoriensis is LBB3T (=ATCC BAA-922T=LMG 22234T).
