[Effect of carbohydrates in the culture medium on amino acid composition of a cephalosporin C producer].
The intracellular and extracellular amino acid composition of an auxotrophic methionine-deficient strain of Acremonium chrysogenum was studied in respect of the content of various carbohydrates in the fermentation medium. In the presence of glucose, an intensive involvement of exogenous DL-methionine into the cell metabolism was observed at earlier stages than in the presence of dextran or succrose. The total content of intracellular amino acids was lower in the cells grown on the medium with glucose. The production of cephalosporin C depended on the intracellular content of methionine, glutamic acid and lysine.
