Abstract:

Based on the fundamental principle of no effect on the present agricultural structure of planting grain crops for food security and cash crops when developing bio-energy industry in China, the authors calculated the ethanol potential yield from sugar beet by using marginal land in North, Northeast and Northwest China, and the ways to increase energy beet adverse resistance and fermentable sugars was also analyzed. The paper summarized the progress of research and development on alcohol fermentation of sugar beet, which including methods of pretreatment for raw material, breeding of efficient yeasts, optimizing of fermentation condition and multipurpose utilization of industrial waste of alcohol fermentation. Sugar beet is regarded as a energy crop having strong and comprehensive ability of coping with salt and alkaline，which has important values for alcohol production. This article indicated the main factors for industrialization of alcohol fermentation of sugar beet are raw material stable supplying, efficient yeasts breeding, and by-product processing based on eco-environmental protection.
