一种利用绿藻生物质发酵生产燃料乙醇的方法
摘要：
本发明提供了一种利用绿藻生物质发酵生产燃料乙醇的方法。具体方法为：利用绿藻作为生物质原料进行乙醇发酵的技术方法，用绿藻、不同硫酸水解浓度以及调节钠离子浓度提升乙醇产量。石莼葡萄糖含量丰富,作为发酵乙醇的原料是十分有潜力的。预处理过程中最适硫酸浓度为2％，并利用氢氧化钙调节pH值为5.5时，其最大乙醇浓度可高达30g/L，且产乙醇速率可达0.63g/(L.h)，乙醇产量为37g/kg。
摘要（英）：

The invention provides a method for producing fuel ethanol by fermentation of green alga biomass. The specific method is a technical method that green alga is used as a biomass raw material for alcoholic fermentation, and the green alga, different sulfuric acid hydrolysis concentration and adjusting sodium concentration are used for increasing ethanol yield. The content of ulva glucose is rich, and it is very potential that the ulva glucose is used as the raw material for alcoholic fermentation. The optimum concentration of sulfuric acid is 2% in the pretreatment process, the maximum concentration of ethanol can be as high as 30 g/L when the pH value is adjusted to 5.5 by using calcium hydroxide, the rate of ethanol production can be as high as 0.63 g/(L.h), and the yield of the ethanol is37 g/kg.
