ABSTRACT
Acid hydrolysis of lignocellulosic biomass results in the release of various sugars as well as inhibitory compounds such as furfural, 5-hydroxymethylfurfural (HMF), vanillin, and vanillic acid that could inhibit microbial growth and ethanol fermentation. During the process of acid hydrolysis of pinewood sawdust conducted in this study, heavy metals such as chromium (Cr) were released from the extruder of the processing reactor. The purpose of this research was to study the effect of selected by-products in an acid hydrolysate on cell growth and ethanol fermentation of Saccharomyces cerevisiae. Furfural, HMF, vanillin, vanillic acid, and Cr were added at ...
