Pichia stipitis Adaptation and Xylose Fermentation in Hydrolysate Solution
摘要
Abstract
Through adapting in steam-exploded corn stalk hyrlrolysate, Pichia stipitis was capable of fermenting xylose to ethanol in presence of inhibitory components. The xylose consumption rate and the elhanol yield were 94, 1 % and 82. 1 % , respectively. Fermentation started al initial xylose concentrations of 30, 45 and 60 g/L. It was found that 45 g/L had a higher average ethanol productivity and a lower average biomaas productivity. According to carbon balance and carbon metabolic effluence analysis, the carbon recovery was 89. 7% , and 48. 5% of carbon was converted to ethanol in the hydrolysate of 51.6 g/L xylose for 36 h.关键词
