为了使生产成本减到最低,并提高从生物质制备生物乙醇的潜力,至关重要的是利用来源于园艺、农业、林业、木材业等的廉价副产品形式的木质纤维生物质,例如利用诸如稻草、玉米秆、林地废弃物、锯屑和木屑的物料,由这类生物质制备的乙醇也被称为第二代生物乙醇。木质纤维生物质包含有半纤维和纤维形式的糖聚合物。在糖发酵成乙醇之前,糖聚合物必须先分解成糖单体,分解聚合物的常用方法是利用酶水解。为了提
In order to minimize production costs and increase the potential for bioethanol production from biomass, it is of paramount importance to utilize lignocellulosic biomass in the form of cheap by-products derived from horticulture, agriculture, forestry, timber industry, etc., , Corn stalks, woodland waste, sawdust and sawdust, and ethanol made from this type of biomass is also known as second generation bioethanol. Lignocellulosic biomass contains sugar polymers in the form of hemicelluloses and fibers. Before the sugar is fermented into ethanol, the sugar polymer must first decompose into sugar monomers, and the common method of breaking down the polymer is by enzymatic hydrolysis. To mention
