Abstract: The influence of regulating the pH value of medium on xylanase synthesis by Trichoderma reesei Rut C 30 was investigated. The result indicated that the xylanase activity was increased obviously when the pH value of medium was controlled at 4.0, and especially, the pH value 4.0 had a more marked effect on β xylosidase activity. Furthermore, the better time that regulating the pH value was from one day to two days.
