摘　　要：利用柑橘皮渣生物转化燃料乙醇是一种生产乙醇的安全可再生的方法。以柑橘皮渣为原料,通过酶或酸进行水解成可发酵糖液,利用糖酵解途径发酵乙醇的微生物将其转化为乙醇,提取脱水到99.5%浓度即得到燃料乙醇。这旨在解决柑橘产业大量副产物皮渣造成的环境污染资源浪费,同时生产乙醇作为枯竭的石油能源替代品。柑橘皮渣转化乙醇中,D-柠檬烯严重抑制微生物发酵,但合理控制各种影响因素可达到较高的乙醇产量。文中对柑橘皮渣生物转化燃料乙醇的过程及影响因素等进行了综述。Biotransformation of citrus peels for making fuel ethanol production is a safe renewable method. With citrus peels as materials by enzymes or acid hydrolysing into fermentable sugar, microorganisms by the glycolytic pathway ferment sugar into ethanol, and extract concentration of 99.5% dehydrated ethanol which are fuel ethanol. This is designed to address a large number of by-products of citrus industry that caused environmental pollution, while producing ethanol as the depletion of oil energy alternatives. D-limonene inhibits microbial fermentation when biotransformation of citrus peels, but the reasonable control of various factors will reach a high ethanol production. Citrus peels by biotransformation for making fuel ethanol and affecting factors were reviewed, which would provide valuable references for utilization of citrus peels and bio-ethanol production.
