influence of glucose and ethanol on enzymic hydrolysis of steam-exploded bagasse

The rate of enzymic hydrolysis of steam-exploded bagasse was found to decrease linearly with increasing concentration of glucose and ethanol, with complete cessation of reaction predicted in the presence of glucose at 11% and in the presence of ethanol at 29%. The combined effects of glucose and eth...

Beschreibung
Zusammenfassung:	The rate of enzymic hydrolysis of steam-exploded bagasse was found to decrease linearly with increasing concentration of glucose and ethanol, with complete cessation of reaction predicted in the presence of glucose at 11% and in the presence of ethanol at 29%. The combined effects of glucose and ethanol were found to be additive. The significantly greater tolerance of the enzyme to ethanol can be utilised in the simultaneous hydrolysis and fermentation of bagasse cellulose to improve hydrolysis rate. Cellulase from Trichoderma reesei was used in these experiments.
