Title: Citric acid fermentation by gamma ray induced mutants of Aspergillus niger in different carbohydrate media
Abstract: A natural isolate of Aspergillus niger, CA16, and two of its second step mutants, 13640 and 27730, 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.
