选取了以面包树木、SC9为代表的11种木薯品种,分别测定其淀粉含量,并从生料及熟料转化乙醇2个方面对这11种木薯材料进行了比较试验。结果表明,各品种之间淀粉含量存在一定差异,其中SC9最高,淀粉含量达82.33%。熟料发酵生产乙醇明显高于生料发酵,且不同品种乙醇产量存在差异,其中生料发酵最高为H680,乙醇产量9.7%,熟料发酵最高为H609,乙醇产量达13.8%。 Eleven kinds of cassava varieties represented by bread tree and SC9 were selected, and their starch content was measured separately. The 11 kinds of cassava materials were compared from two aspects of raw materials and clinker into ethanol. The results showed that there was a certain difference in the starch content among the varieties, of which SC9 was the highest and starch content was 82.33%. The ethanol production from clinker fermentation was significantly higher than that from raw meal fermentation, and the yield of different varieties of ethanol was different. The highest raw material fermentation was H680, the yield of ethanol was 9.7%, the highest fermentation of clinker was H609, the yield of ethanol reached 13.8%.
