Bacillus brevis is a Gram-positive aerobic spore-forming bacillus commonly found in soil, air, water, and decaying matter. It is rarely associated with infectious diseases.[1] The antibiotics gramicidin and tyrocidine were first isolated from it. [2]

Bacillus brevis forms gram positive (variable) rods with optimal growth of 35-55C. It is a motile spore former with positive catalase activity. Amylase negative, casein negative, gelatinase positives, indole negative, VP negative and most are citrate utilizers.
