Alkalihalobacillus alcalophilus (formerly Bacillus alcalophilus) is a Gram-positive, rod-shaped species of bacteria. Likely strains of this species have been isolated from highly alkaline waste water. A. alcalophilus is a moderate halotolerant obligate alkaliphile growing at 40 ðC and at pH 9âÂÂ10.5 (and possibly higher) that has been isolated from soil and animal manures.
This species was transferred into the genus Alkalihalobacillus in 2020 after a phylogenomic study to resolve the polyphyly of the genus Bacillus.
A draft genome of A. alcalophilus strain AV1934 has 4,348,660 bp, with 3,745 predicted proteins. The G+C content of the genome is 37.2%. Another draft genome has 4,095 predicted genes and 4,063 predicted proteins.
