Bacillus alcalophilus

Bacillus alcalophilus is a Gram-positive, rod-shaped species of bacteria. Likely strains of this species have been isolated from highly alkaline waste water. B. 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]
