Bacillus halodurans is a rod-shaped, Gram-positive, motile and spore-forming bacterium found in soil. In a genomic comparison with Bacillus subtilis, B. halodurans strain C-125 - originally an unclassified Bacillus strain[2] - was found to contain unique genes and sigma factors that may have aided its adaptation to more alkaline environments.[3]

This species has been recently transferred into the genus Alkalihalobacillus. [4] The correct nomenclature is Alkalihalobacillus halodurans.

Bacteriocin production

[edit]

B. halodurans produces a bacteriocin, haloduracin, that may be useful as a lantibiotic and could be produced in large quantities by solid state fermentation.[5]

Genome structure

[edit]

B. halodurans has a genome that contains 4.2 Mbp with 4,066 protein coding genes.[3][6]
