The amino acids in an acid hydrolysate of casein were catabolized more extensively by Megasphaera elsdenii than those in an enzymic hydrolysate. Threonine and serine were most actively degraded, but no resultant increase in growth yield occurred. Branched-chain volatile fatty acid production, which increased as the dilution rate of a glucose-limited chemostat decreased, seemed to be associated with maintenance rather than with growth.
