Abstract
Sugar cane bagasse hemicellulose hydrolyzate was prepared by dilute su lfuric acid (3% w/v) hydrolysis with a high-solid, low-liquid ratio fo llowed by leaching. The hydrolyzate contains 11% (w/v) of fermentable sugars with xylose as the major component, which comprises up to 75% o f the total reducing sugars. The neutralized hydrolyzate exhibited str ong inhibition toward cell growth and ethanol production by yeasts. Th e inhibitory effect of hydrolyzate can be alleviated by treating hydro lyzate either with ion-exchange resins or with acidified activated cha rcoal.
