摘要
Utilizing cane molasses as substrate, semi-pilot scale production of citric acid was investigated in fermentation trays (40 × 35 cm) with several gamma-ray induced mutants of Aspergillus niger. Of the mutants tested, two were found to have high yield efficiency (1420, 51.06%; 7920, 50.35%) of sugar to citric acid. The yield of other mutants (HB3, 1020, 16420, 27730 and 11240) ranged between 30 to 42%. The prospect of utilizing the high yielding mutants for commercial production of citric acid have been discussed.
