Alkalihalobacillus alcalophilus explained
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 °C and at pH 9–10.5 (and possibly higher) that has been isolated from soil and animal manures.[1] [2]
This species was transferred into the genus Alkalihalobacillus in 2020 after a phylogenomic study to resolve the polyphyly of the genus Bacillus.[3]
Genome
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.[4]
