Determination of some physiological factors affecting xylanase production from Trichoderma harzianum 1073 D3.
In this study, different Trichoderma strains were tested and Trichoderma harzianum 1073 D3 was found to be the most potent xylanase producer. Then some cultural parameters, namely, incubation time, substrate concentration, initial culture pH and temperature were optimized in order to increase xylanase production from Trichoderma harzianum 1073 D3. The optimum incubation time was found to be 13 days. It was concluded that 1% xylan concentration is suitable for high xylanase production rate. The optimum temperature and pH were found to be 30 degrees C and 7, respectively. Also, it was determined that agitation during growth was suitable for efficient production.
