摘　　要：以海带中含有的不同糖类为碳源,利用棕榈发酵细菌进行乙醇发酵研究,结果显示,Z.palmae可以直接利用甘露醇、葡萄糖、半乳糖、岩藻糖、昆布淀粉为碳源发酵产乙醇,最大乙醇产量分别为6.92g/L、5.86 g/L、4.72g/L、5.34g/L、6.16g/L,相应乙醇转化率分别为0.346g、0.293g、0.236g、0.267g、0.308g乙醇/g底物;但是,Z.palmae不能在以褐藻酸、褐藻糖胶、甘露糖、木糖、鼠李糖、阿拉伯糖、肌醇为唯一碳源的培养基上正常生长。In this paper, the main constituent sugars of brown algaes were used as substrates to carry out the fermentation experiments by Zymobacter palmae. Results showed that different carbons had significantly effects on ethanol production by Z. palmae. The results showed that the carbohydrates including mannitol, glucose, galactose, fucose and laminarin could be utilized by the bacteria, the maximum ethanol production was 6.92g/L, 5.86g/L, 4.72g/L, 5.34g/L, 6.16g/L, respectively. The relevant ethanol conversion rates were 0.346g, 0.293g, 0.236g, 0.267g, 0.308g ethanol/g substrate, re- spectively. However, the carbohydrates including alginic acid, fucoidan, mannose, xylose, rhanmose, arabinose and inositol could not be utilized by the bacteria.
