| Abstract: | The study were carried out to measure the properties of xylanase by bacillus subtilis XY1905 which was screened from the soil. The result showed that the optimal conditions for measuring the activity of xylanase were: reaction pH 6.0, reaction time 10 min. reaction temperature 60℃. Xylanase is stable when heated and 96.44% of activity remained after 1h at 80℃. It is unsensitive to metalli cions. |
