问题陈述：工业和国内对不可再生能源的需求不断增加，导致化石燃料迅速枯竭。这导致从玉米和玉米等粮食作物发酵中提取的生物乙醇的出现，从而提高了食品商品的价格。基于富含复杂碳水化合物（例如纤维素）的原材料的第二代生物乙醇减少了与食品工业的竞争。烟草在世界各地的大片土地上种植，每年产生多次收成，从而产生大量廉价的绿色生物质。获得第二代生物乙醇的过程包括四个基本步骤：预处理、酶水解、糖发酵和乙醇回收。
Statement of the Problem: The escalating industrial and domestic demands on non-renewable energy resources have led to the rapid depletion of fossil fuels. This has resulted in the emergence of bioethanol derived from fermentation of food crops such as maize and corn which has increased the prices of food commodities. Second generation bioethanol based on raw materials rich in complex carbohydrates such as cellulose reduces the competition with the food industry. Tobacco is grown in large fields all over the world and generates multiple harvests per year, thus producing large amounts of inexpensive green biomass. The process to obtain second generation bioethanol involves four basic steps: pretreatment, enzymatic hydrolysis, sugar fermentation and ethanol recovery.
