【中文摘要】 研究了豆渣和酒石酸銨(濃度分別為1%、2%、3%、4%和5%),對靈芝和產朊假絲酵母混菌固態發酵油菜秸稈產木質素降解酶系的影響。結果表明,與對照相比,1%、2%、3%和5%的豆渣組中的漆酶、錳過氧化物酶和木質素過氧化物酶酶活性均未受顯著性影響,而在4%豆渣組中,這3種酶的活性顯著提高,分別為440.33 U·L-1、473.33 U·L-1和98.49 U·L-1,分別是對照的2.03倍,2.16倍和2.86倍。與對照相比,1%、2%、3%、4%和5%的酒石酸銨組中,3種木質素降解酶的活性均無顯著性影響,因此有機氮豆渣好于酒石酸銨,其最佳濃度為4%。
【英文摘要】 Effects of the organic bean dregs powder and ammonium tartrate dibasic at the concentration of 1%,2%,3%,4% and 5%on the production of ligninolytic enzyme system under solid-state co-fermentation of Ganoderma lucidum and Candida utilis in cole stalk medium were studied.The results showed that compared with the control team,it did not affect the activities of laccase,manganese peroxidase and lignin peroxidase significantly,when nitrogen sources was bean dregs powder of 1%,2%, 3%and 5%.However the activities of laccase,manganese peroxidase and lignin peroxidase were increased significantly when nitrogen sources was 4%bean dregs powder,and the activities of three enzymies were 440.33 U·L-1,473.33 U·L-1 and 98.48 U·L-1 respectively which were 2.03,2.16 and 2.86 times compared to the control team.Compared with the control team,it did not affect the activities of laccase,manganese peroxidase and lignin peroxidase significantly,when nitrogen sources was 1%, 2%,3%,4%and 5%ammonium tart...更多rate dibasic.Organic bean dregs powder was better than the ammonium tartrate dibasic as nitrogen sources,whose best concentration was 4%. 還原
