Abstract: | The feasibility of utilizing the rapidly growing tropical woods for ethanol production by Neurospora crassa has been studied. Hydrolysis of cold alkali pretreated wood gave a saccharification of 68% based on the available carbohydrate. The direct fermentation of pretreated wood (20 g l?1) by Neurospora crassa gave quantitative conversion of available hemicellulose/cellulose to ethanol in 5 days. Increasing the substrate concentration to 50 g l?1lowered the conversion to 40–60% yielding 12 g l?1of ethanol. Fermentation of wood (50 g l?1) pretreated with hot 1 m NaOH followed by neutralization with HCl gave only 6 g l?1of ethanol. |
