Abstract excerpt
Studies of L, D and DL-forms of glutamic acid as the sole nitrogen source or as a supplement to the major nitrogen source--ammonium sulphate have demonstrated that in the first case all forms of glutamic acid are assimilated by auxotrophic mutants--lysine producers. However, the lysine synthesis was very low, when L-glutamic acid was used as the only nitrogen source. Glutamic acid at a concentration of 0.01 M...
