| Abstract: | The rate of total extracellular xylanase production in Trichoderma reesei, QM 9414, system was affected by temperature and pH. In vitro studies with xylanase showed different temperature optima for activity in presence and in absence of xylan as substrate. Similar behaviour was observed in the pH studies. A number of temperature and pH optima also suggested the multiple nature of xyalanase. |
