Biotechnology Letters Aims and scope Submit manuscript

Summary

Semi-pilot scale production of citric acid was investigated with a gamma-ray induced mutant (HB3) of Aspergillus niger using 500, 1000 and 1500 ml medium in 51 fermentation jars. Yield of citric acid was found to be seven-fold higher compared to the parent in 1000 ml medium and the corresponding increase was two-fold in the 500 ml medium. With 1500 ml/fermentation jar the yield was low with both the parent and the mutant strain though the mutant gave higher yield compared to the parent.
