【Abstract】 The abilities of four Neurospora crassa and four Fusarium oxysporum strains in cellulase production and direct conversion of cellulose to ethanol were investigated, and the high ethanol producer, N. crassa As 3.1602, was selected for further study. The cell growth, cellulase production and direct conversion of cellulose to ethanol of N. crassa AS 3.1602 was studied. After optimization, the ethanol production and the yield reached 6.7 g/L and 33.5 %, respectively.更多还原
