Pretreatment effects on orange processing waste for making ethanol by simultaneous saccharification and fermentation.

Abstract

Citrus processing waste (CPW) pretreated under different times, pH and temperatures was investigated. Pretreatments at 160 degrees C for longer than 4 min with steam purging were needed to remove limonene, an inhibitor for fermentation, to below 0.1%. While hemicelluloses were solubilized well following all pretreatments at 160 degrees C, just 70% of the… (More)
