概要

• 論文の詳細を見る

• A natural isolate of Aspergillus niger, CA16,and two of its second step mutants, 136/40 and 277/30,grown on different sugar substrates gave maximum citric acid yields of 34,70,and 126 mg/ml respectively in sucrose medium. Combination of two sugars in the medium at 50% of each improved the yields of citric acid for the sucrose : glucose, glucose : sorbitol, glucose : xylose, and xylose : sorbitol combinations with the mutant strains. Inclusion of galactose in combinations decreased the citric acid yield.
