[Effect of some amino acids on the biosynthesis of glucoamylase by cultured Endomycopsis species].
The effect of amino acids (glutamic, aspartic, beta-alanine, phenylalanine, methionine) on the glucoamylase biosynthesis by Endomycopsis species 20-9 was studied. Monoaminodicarboxylic acids produced a stimulating effect on the glucoamylase synthesis. Their addition at optimal concentrations of 0.2 to 0.4% increased by 54--69% glucoamylase activity of Endomycopsis sp. 20-9 upon submerged cultivation on the medium containing 3% maize extract and 1% starch. An application of this amino acid nutrition during cultivation did not produce a significant effect on the microbial glucoamylase activity.
