10.22376/ijpbs.2019.10.1.p1-12 Volume 4 Issue 1 2013 (January - March) Saw dust, rice husk and bagasse were studied as substrates for xylanase production from a lessThan i greaterThan Trichoderma lessThan /i greaterThan culture using solid state fermentations (SSF). The characterization of the enzyme was perfomed for xylanase activity. It was found that out of the three substrates used saw dust acted as the best substrate for production of xylanase. The xylanase extracted was found to have an optimal pH 5 and optimal temperature 50 lessThan sup greaterThan o lessThan /sup greaterThan C.
