Abstract
The ability of two species of Bacillus to degrade child's scalp hair, cow h orn, cow hooves, and human nails in vitro under static conditions was studi ed by the determination of soluble sulphhydryl compounds as cysteine, disul phides as cystine, and release of extracellular keratinase along with chang es in alkalinity of the culture filtrate. Child's scalp hair was found to b e the most favored keratin substrate for Bacillus spp.
