| Abstract: | The course of xylanase production from Penicillium sp. P1 and conditions such aseffects of nitrogen component,additives,initial pH, inoculum size and temperature on enzymeproduction were investigated. The enzyme activity was 1353. 5IU/g dry medium at 28℃af ter 4 days cultivation. The optimal temperature and pH were 50℃ and 4. 6 respectively. Xylanase was stable under 50℃. |
