Optimization of pectinase production from fungus and its application in flax roving
The conventional method is used to get the optimal conditions of pectinase production from fungus in this paper, temperature, pH, nitrogen source, carbon source and shaker speed are involved in the experiments, then the optimal conditions of pectinase production from the fungus are obtained, that is, pH6, nitrogen source potato, carbon source pectin, cultural temperature 30℃, shaker speed 200r/min. Then flax roving is treated with fungus under its optimal pectinse production conditions and its residual gum contents is 17.63％. Last comparisons are made between unretted and retted flax roving by components, SEM, and infrared spectrum. Treated rovings with chemical-treatment and microbe-treatment are also compared by properties, which proves that microbe treatment of flax roving is feasible.
