Maximization of xylanase activity at different media, temperature, pH and salt concentration has been presented in this paper. YpSs, Czapek dox and Malt extract medium were taken for evaluation of optimum growth and activity. Amongst all tested media, YpSs showed the highest growth. Three different natural carbon substitute i.e., wheat husk, rice husk and sugarcane baggase were used for xylanase activity. Maximum enzyme activity was observed in test fungus at rice husk. Production and maximum xylanase activity at rice husk has been observed at different temperatures, pH and Salt concentrations. The highest xylanase activity has been observed on day 5 at temperature 32° C, pH 6.5 and salt concentration of 2%.
