title: Production of extracellular lysine by a strain of Bacillus coagulans. Identification and requirements for growth and lysine accumulation.
abstract: A naturally deficient thiamine and methionine requiring strain of Bacillus coagulans (Ms 5) accumulates lysine in medium only when exogenous pyridoxine (optimal concentration, 0.1 mu g/ml) are supplied. Threonine exerts an inhibitory effect at higher  concentrations but pyridoxine does not.
