TL;DR: In this paper, a strong base anion exchange resin resin is conditioned with a low concentration of hydroxyl (for example, an NaOH solution with a concentration between 0.1 and 1000 nM), most preferably between 1 and 10 mM, and the conditioned resin separates a number of sugar and sugar alcohols from one another, while still allowing ready desorption from the resin.
Abstract: Improved separations of xylose, mannose, galactose, arabinose, glucose, xylitol, arabitol, sorbitol, galactitol, or mannitol (and other monosaccharides and sugar alcohols) from other sugars and sugar alcohols may be achieved by chromatography over hydroxyl-form anion exchange surfaces prepared from anion exchange resins at relatively low hydroxyl concentrations. When a strong base anion exchange resin, such as a chloride-form strong base anion exchange resin, is conditioned with a low concentration of hydroxyl (for example, an NaOH solution with a concentration between 0.1 and 1000 nM, most preferably between 1 and 10 mM), the conditioned resin separates a number of sugars and sugar alcohols from one another, while still allowing ready desorption from the resin.

TL;DR: Depending on the fermentation conditions used, the yeast Zygosaccharomyces rouxii ATCC 12572 will give either ethanol or various polyols as main fermentation product(s).
Abstract: The yeastZygosaccharomyces rouxii ATCC 12572 was selected for its ability to produce appreciable levels of ethanol and of various polyols from concentrated glucose media (20 %, w/v).Z. rouxii was shown to yield large quantities of glycerol and of the mixture arabitol + mannitol. Good agitation combined with appropriate aeration (1 vvm) allowedZ. rouxii to utilize glucose readily leading to high polyol production. Depending on the fermentation conditions used,Z. rouxii ATCC 12572 will give either ethanol or various polyols as main fermentation product(s).

TL;DR: An endophytic yeast, Rhodotorula mucilaginosa strain PTD3, demonstrated an exceptional ability to ferment the hydrolysate, overcome hexose repression of xylose utilization with a short lag period of 10 h, and tolerate sugar degradation products.
Abstract: An endophytic yeast, Rhodotorula mucilaginosa strain PTD3, that was isolated from stems of hybrid poplar was found to be capable of production of xylitol from xylose, of ethanol from glucose, galactose, and mannose, and of arabitol from arabinose. The utilization of 30 g/L of each of the five sugars during fermentation by PTD3 was studied in liquid batch cultures. Glucose-acclimated PTD3 produced enhanced yields of xylitol (67% of theoretical yield) from xylose and of ethanol (84, 86, and 94% of theoretical yield, respectively) from glucose, galactose, and mannose. Additionally, this yeast was capable of metabolizing high concentrations of mixed sugars (150 g/L), with high yields of xylitol (61% of theoretical yield) and ethanol (83% of theoretical yield). A 1:1 glucose:xylose ratio with 30 g/L of each during double sugar fermentation did not affect PTD3’s ability to produce high yields of xylitol (65% of theoretical yield) and ethanol (92% of theoretical yield). Surprisingly, the highest yields of xylitol (76% of theoretical yield) and ethanol (100% of theoretical yield) were observed during fermentation of sugars present in the lignocellulosic hydrolysate obtained after steam pretreatment of a mixture of hybrid poplar and Douglas fir. PTD3 demonstrated an exceptional ability to ferment the hydrolysate, overcome hexose repression of xylose utilization with a short lag period of 10 h, and tolerate sugar degradation products. In direct comparison, PTD3 had higher xylitol yields from the mixed sugar hydrolysate compared with the widely studied and used xylitol producer Candida guilliermondii.

TL;DR: To evaluate the effect of modifications of water activity of a molasses medium with different solutes on growth, intracellular water potentials and endogenous accumulation of polyols/sugars in the biocontrol yeast Candida sake.
Abstract: Aim: To evaluate the effect of modifications of water activity (a(w) 0.996-0.92) of a molasses medium with different solutes (glycerol, glucose, NaCl, proline or sorbitol) on growth, intracellular water potentials (psi(c)) and endogenous accumulation of polyols/sugars in the biocontrol yeast Candida sake. Methods and Results: Modification of solute stress significantly influenced growth, psi(c) and accumulation of sugars (glucose/trehalose) and polyols (glycerol, erythritol, arabitol and mannitol) in the yeast cells. Regardless of the solute used to modify a(w), growth was always decreased as water stress increased. Candida sake cells grew better in glycerol- and proline-amended media, but were sensitive to NaCl. The psi(c) measured using psychrometry showed a significant effect of solutes, a(w) and time. Cells from the 0.96 a(w) NaCl treatment presented the lowest psi(c) value (-5.20 MPa) while cells from unmodified media (a(w) = 0.996) had the highest value (-0.30 MPa). In unmodified medium, glycerol was the predominant reserve accumulated. Glycerol and arabitol were the major compounds accumulated in media modified with glucose or NaCl. In proline media, the concentration of arabitol increased. In glycerol- and sorbitol-amended media, the concentration of glycerol rose. Some correlations were obtained between compatible solutes and psi(c). Conclusions and Significance: This study demonstrates that subtle changes in physiological parameters significantly affect the endogenous contents of C. sake cells. It may be possible to utilize such physiological information to develop biocontrol inocula with improved quality.
