Thus, a research on the modification of the physical conditions of the solid state culture system, specifically different initial moisture content, fermentation temperature, inoculums size and different percentage of carbon and nitrogen sources were conducted to compare the usage of two different lignocellulosic materials which were oil palm frond and banana petiole respectively. After using a conventional method （one factor at a time）, the optimum fermentation conditions would be a combination of 70% initial moisture content （v/w）, at 28 ~C fermentation temperature with supplementation of 1% sucrose （w/w） and 1% peptone using 1 mL of inoculum in order to achieve highest xylanase production which was 1,711.87 U/mL and 1,579.60 U/mL for oil palm frond and banana petiole respectively. It was suggested that oil palm frond showed higher xylanase production compared to banana petiole.展开更多
