ABSTRACT:
Method of preconditioning acid hydrolyzates derived from lignocellulosic materials such as sawdust or newspaper and preconditioned acid hydrolyzates are provided. The preconditioning negates the effect of substances which tend to inhibit fermentation and comprises a series of steps including steam-stripping, calcium oxide treatment at a pH of 10 to 10.5, adjusting the pH to about 6 to 7 with a mineral acid and especially phosphoric acid and concentrating the hydrolyzate solution to a glucose concentration of less than 150 grams per liter. Glucose contained in such preconditioned hydrolyzates is readily fermentable to ethyl alcohol, in theoretical yield, after fermentation for as short a period as 1 to 2 hours.
