生物转化食用菌菌糠木质纤维素产燃料乙醇的研究进展

Research progresses on bioconversion of spent mushroom substrate lignocellulose for fuel ethanol production

近年来,食用菌生产技术在世界各国得以广泛普及,全球食用菌菌糠(spent mushroom substrate,SMS)总产量也随之大幅增长。随着全球性能源危机的到来,利用可再生纤维素类物质生产燃料乙醇已引起世界各国的高度重视。食用菌菌糠是食用菌子实体采收后的固体废弃物,其含有纤维素、半纤维素、木质素、抗营养因子和胞外纤维素降解酶类等组分,具备了作为第二代生物乙醇转化基质的潜力,基于此,该文对当前利用食用菌菌糠生物转化生产乙醇的研究进展和应用前景进行了阐述。

In recent years,edible fungus production technology has been widely spread all over the world,and the total output of spent mushroom substrate( SMS) has been significantly increased. With the severe circumstances of the global energy crisis,more and more attention has been focused on how to use the renewable fiber material to produce bioethanol. As the solid waste of mushroom,SMS contains lots of nutritional ingredients,such as cellulose,hemicellulose,lignin,anti-nutrition factor and extracellular cellulose degradation enzymes,and possesses the potential of second-generation bioethanol conversion. The second-generation bioethanol made from lignocellulosic biomass is considered to be one of the most promising biofuels. Based on this fact,this paper mainly elaborated the research progresses and application prospect on the utilization of SMS for ethanol bioconversion.
