Bacillus halodurans

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]

Bacillus halodurans
Scientific classification
Kingdom:
Bacteria
Phylum:
Bacillota
Class:
Bacilli
Order:
Bacillales
Family:
Bacillaceae
Genus:
Bacillus
Species:
B. halodurans
Binomial name
Bacillus halodurans
(ex Boyer et al. 1973) Nielsen et al. 1995[1]

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

Bacteriocin production

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

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