TL;DR: The various hemicelluloses structures present in lignocellulose, the range of pre-treatment and hydrolysis options including the enzymatic ones, and the role of different microbial strains on process integration aiming to reach a meaningful consolidated bioprocessing are reviewed.

TL;DR: This review summarizes recent research aiming at developing industrial strains of Saccharomyces cerevisiae with the ability to ferment all lignocellulose-derived sugars with the potential of pentose fermentation in improving lignOcellulosic ethanol production.

TL;DR: This is the first report that characterizes the molecular mechanisms for improved mixed-pentose utilization obtained by evolutionary engineering of a recombinant S. cerevisiae strain and indicated that the selection pressure during prolonged continuous culture resulted in the improved transport of xylose and arabinose as well as increased levels of the enzymes from the introduced fungal Xylose pathway.

TL;DR: This review aims to briefly summarize current knowledge on the biochemical and molecular features of the transporters of hexoses and pentoses in yeasts, when possible establishing links between previous kinetic studies and genomic data currently available.

TL;DR: The glucose/xylose facilitator Gxf1 from Candida intermedia was expressed in the recombinant xylose-fermenting Saccharomyces cerevisiae strain TMB 3057 and the new strain, TMB 3411, displayed approximately two times lower Km for xylOSE transport compared to a control strain not expressing Gxf 1.
