Abstract

Enzymatic property of xylanase from Trichoderma RS30 was studied in this paper.The result showed that the optimum temperature was 50℃-55℃ and the thermal stability of xylanase decreased with the increasing temperature.The optimum pH was 5.5 and the optimum rang of pH was 4.5-7.5 when the activity of xylanase was stable.This xylanase was enzyme specificity for hydrolysis oat xylan.Mn2+ and Ca2+ had activation on xylanase but not Fe2+ and Co2+.
