| Abstract: | The conditions of xylanase production with submerged culture by a wild type strain Trichoderma sp. T6 were studied. Natured material straw (ρB = 30 g/L)was the best carbon source. As nitrogen source urea (ρB = 1 g/L) was beneficial to the biosynthesis of xylanase. The influences of initial pH, incubation temperature and inoculum size on the biosynthesis of xylanase of strain T6 were also studied. Under determined condition, 30℃ after cultured 4.5d, xylanase activity was as high as 91 IU/mL. |
