โœฆ Synopsis


Semi-pilot scale production of citric acid was investigated with a gala-ray induced mutant (HB3) of Aspergillus niger using 500, i000 and 1500 ml medium in 51 fermentation jars.

Yield of citric acid was found to be sevenS'old higher compared to the parent in i000 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.
