CITRIC ACID PRODUCTION BY ASPERGILLUS ORYZAE AD-2: PROCESS OPTIMIZATION AND YIELD ENHANCEMENT

Results: In the present study, an attempt was made to produce citric acid using Aspergillus oryzae. The optimum condition for citric acid production was determined. pH at 3, temperature at 30 ˚C and 1% inoculums size was found to be optimum. The enhanced citric acid production was seen using UV- mutation; however immobilization method did not enhance the yield.
