CHAPTER # 1: LITERATURE REVIEW Gardnerj et al (1956) investigated citric acid production by mutants of Aspergillus niger. The strain of Aspergillus niger was improved by X-rays and ultraviolet irradiations and found that as compared to wild, the mutated strain give more yield of citric acid. They concluded that 80 % of the sugar fermented was obtained in aerated culture, whereas only 21 % was obtained with the parent strain. Banik et al (1980) adopted the chemical mutagenic treatment of Aspergillus niger for the improved production of humic acid. Ethylene imine was used as a mutagen for this purpose. The mutagenic strain gave 9.8g/l yield compared to 3g/l yield of non-mutated parental strain. Kiel et al (1981) reported the use of cotton waste as a carbohydrate source for the…show more content…
