Abstract Bacillus strain JF-2 (ATCC 39307) is a halotolerant, biosurfactant-producing bacterium that was initially described as a member of the species Bacillus licheniformis based on a limited set of phenotypic characteristics. Here, genetic and phenotypic analyses were employed to determine the relationship of Bacillus strain JF-2 to other Bacillus strains. The restriction patterns with AluI and analysis of gyrA and 16S rRNA gene sequences grouped Bacillus strain JF-2 with B. mojavensis(T) and not with B. licheniformis(T). DNA-DNA similarity showed JF-2 was 75\% similar to B. mojavensis(T) and only 11\% similar to B. licheniformis(T). Both strain JF-2 and B. mojavensis(T) required DNA for anaerobic growth, but B. licheniformis(T) did not. B. mojavensis(T) and strain JF-2 did not grow anaerobically in thioglycollate medium or aerobically with propionate while B. licheniformis(T) grew under these conditions. DNA-DNA similarity, gene sequence data and phenotypic characteristics all support the assignment of JF-2 as a member of the species B. mojavensis.
