Abstract

A combined enzymatic hydrolysis and fermentation (CHF) process was used to convert steamtreated wheat and barley straw to ethanol. Maximum conversion efficiencies were obtained when the substrates were steamed for 90 s. These substrates could yield over 0.4g ethanol/g cellulose following a CHF procedure using culture filtrates derived from Trichoderma harzianum E58. When culture filtrates from T. reesei C30 and T. reesei QM9414 were used, the ethanol yields obtained were 0.32 and 0.12 g ethanol/g cellulose utilized, respectively. The lower ethanol yields obtained with these strains were attributed to the lower amounts of ß-glusocidase detected in the T. reesei culture filtrates. Keywords: cellulases, combined hydrolysis and fermentation: Tricholderma: agricultural residues.
