Abstract

Various parameters like pH, temperature, substrate concentration, incubation period and yeast extract concentration have been used in estimating the enzyme production by Aspergillus terreus. Incubation period was optimized on 8th day of fungal inoculation at 6.0 pH, 40°C temperature and 2% wheat bran was used as substrate for optimum production of xylanase. Total 5 mg/ml phosphate buffer and birch wood xylan were taken as substrate at a pH of 6.5 and the temperature of 55°C for xylanase activity. Thus xylanase preparation by this fungus was optimum at 40°C and this enzyme was found to be thermophilic in nature.
