Tolerance and adaptation of ethanologenic yeasts to lignocellulosic inhibitory compounds
TL;DR: A net loss of performance was evident from both strains, indicating the absence of adaptation to the substrates, regardless of the sequence in which the SSL types were employed, and surprisingly, acetic acid had the least impact on sugar consumption rate and ethanol productivity, and stimulated ethanol yield at moderate concentrations.

An ethanologenic yeast exhibiting unusual metabolism in the fermentation of lignocellulosic hexose sugars
TL;DR: Three lignocellulosic substrate mixtures were separately fermented by the industrially employed SSL-adapted strain Tembec T1 and a natural galactose-assimilating isolate (Y-1528) of Saccharomyces cerevisiae to compare fermentative efficacy, and both strains were confirmed as S. Cerevisiae via molecular genotyping.

The fermentability of concentrated softwood-derived hemicellulose fractions with and without supplemental cellulose hydrolysates
TL;DR: In this paper, the water-soluble fractions derived from steam exploded Douglas-fir whitewood and wood chips were subjected to a concentration step (rotary evaporation or freeze-drying) prior to fermentation.

Characterization of a unique ethanologenic yeast capable of fermenting galactose
TL;DR: Screening experiments performed with wild-type Saccharomyces cerevisiae strains have identified a strain that exhibits exceptional fermentative performance on galactose, completely exhausting the sugar in significantly less time (6 h) than that typically required by other S. cerevisia strains tested.

The nature of chromophores in high-extractives mechanical pulps: Western red cedar (Thuja plicata Donn) chemithermomechanical pulp (CTMP)
TL;DR: In this paper, the authors identify three carbonyl-containing chromophores and provide a possible mechanism for their formation during the mechanical pulping process of western red cedar mechanical pulp.
