| 摘 要： | 研究了不同浓度的豆渣(1%~5%)对平菇和灵芝固态发酵油菜秸秆产生木质素降解酶系的影响。结果表明:与对照(无豆渣)相比,浓度为3%、4%的豆渣显著提高平菇产生的锰过氧化物酶(MnP)和木质素过氧化物酶(LiP)活性;漆酶(Lac)的活性也在豆渣浓度为2%~4%时得到显著提高。灵芝发酵基质中,3%的豆渣显著提高了MnP和LiP的活性;浓度为3%~5%的豆渣也可显著提高灵芝发酵基质中Lac的活性,其中豆渣浓度为3%时,平菇与灵芝单菌发酵中Lac的活性都达到峰值,分别为对照的2.3倍、1.67倍。

| Abstract: | Effects of bean dregs powder at different concentrations(1%~5%) on the production of ligninolytic enzyme system of Pleurotus ostreatus and Ganoderma lucidum in the fermentations of rape straw solid-state medium were studied.The results showed that,compared to the control(without bean dregs powder),the manganese peroxidase(MnP) and lignin peroxidase(LiP) activities of P.ostreatus were increased significantly when the concentrations of bean dregs powder were 3% and 4%,2%~4% bean dregs powder increased signifi... |
