Two-stage acidic-alkaline pretreatment of Miscanthus for bioethanol production
Pretreatment is the rate-limiting step for bioethanol production from lignocellulosic biomass, and subsequently intensive studies have been undertaken to improve the pretreatment efficiency. However, so far most pretreatment methods failed to achieve desirable sugar recovery from both cellulose and …

Enhancing Bioethanol Fermentation through Removal of Acetic Acid Using Liquid-Liquid Extraction
… the most ubiquitous fermentation inhibitors in a bioethanol production facility which slows down the bioethanol production and reduces its yield through inhibition of the ethanol producing microorganisms. The use of liquid-liquid extraction has shown to be a viable tool to remove the acetic acid …

Improved xylose fermentation by expression of a putative xylose transporter encoding gene HXT2.4 in Saccharomyces cerevisiae
… the promising microorganisms in lignocellulosic bioethanol production. Unfortunately S. cerevisiae cannot consume xylose, a pentose sugar which comprises almost 30% of lignocellulosic biomass. Metabolic and genetic engineering methods were used to develop S. cerevisiae that could consume xylose. …
