Production of ethanol from Jerusalem artichoke flour by simultaneous saccharification and fermentation
摘要
Abstract
Mycelial pellets formed by Aspergillus niger A⁃15 were used to immobilize the alcohol producing yeast Saccharomyces cerevisiae C⁃15. The operated factors, such as agitation speed, temperature and mixed proportion of strains were studied. The optimal adsorption 66�9% was obtained when speed was 80 r/min, temperature was 40℃ and mixed proportion was 1∶10. With Jerusalem artichoke flour as substrate,12�8%( V/V) of ethanol was produced within 48 h of fermentation by simultaneous saccharification and fermentation using mycelial pellets at 30℃. And mycelial pellets could tolerate 19%(volume fraction) alcohol.关键词
