A current challenge of the cellulosic ethanol industry is the effect of inhibitors present in biomass hydrolysates. Acetic acid is an example of one such inhibitor that is released during the pretreatment of hemicellulose. This study examined the eff

The inhibitory effects of furfural and acetic acid on the fermentation of xylose and glucose to ethanol in YEPDX medium by a recombinant Saccharomyces cerevisiae strain (LNH-ST 424A) were investigated. Initial furfural concentrations below 5 g/L caus

Comprehensive analysis of intracellular metabolites is a critical component of elucidating cellular processes. Although the resolution and flexibility of reversed-phase liquid chromatography-mass spectrometry (RPLC-MS) makes it one of the most powerf

We have developed recombinant Saccharomyces yeasts that can effectively co-ferment glucose and xylose to ethanol. However, these yeasts still ferment glucose more efficiently than xylose. The transport of xylose could be one of the steps limiting the

Recent studies have proven ethanol to be the idael liquid fuel for transportation, and renewable ligno cellulosic materials to be the attractive feed stocks for ethanol fuel production by fermentation. The major fermentable sugars from hydrolysis of

Lignocellulosic biomass, which contains large amounts of glucose and xylose, is the new ideal feedstock for ethanol production used as renewable liquid fuel for transportation. The naturally occurring Saccharomyces yeasts traditionally used for indus

The Escherichia coli araBAD operon consists of three genes encoding three enzymes that convert L-arabinose to D-xylulose-5 phosphate. In this paper we report that the genes of the E. coli araBAD operon have been expressed in Saccharomyces cerevisiae

A new and effective pretreatment process for biomass conversion involves the steeping of biomass in 2.9 M NH4OH. This resulted in the removing about 80–90% of the lignin along with almost all the acetate from cellulosic residues. Based on dry cellu

China is suffering from a sustained shortage of crude oil supply, making fuel ethanol and other biofuels alternative solutions for this issue. However, taking into account the country's large population and dwindling arable land due to rapid urbaniza
