Study on the optimum fermentation condition of producing pectinase by Penicillium expansum using apple pomase
摘要
Abstract
Single factors and orthogonal rotation experiments were carried out to optimize pectinase producing conditions by Penicillium expansum under solid state fermentation. The results showed that the optimum medium compositions were as follows: bran 8.15%, apple pomace 16.5%, (NH4)2SO4 0.86%, MnSO4 0.3% , KCl 0.15%, Tween 80 0.04% and water content 74.0%.Using the optimized medium in 250mL flask,incubating at 28℃ for 96h, activity of pectinase reached 752.29U/g medium.关键词
