The heat conductance across the interface between a phase change material (PCM) and metal shell is important for thermal design of latent storage systems. Non-equilibrium molecular dynamics simulations were carried out in this work to unravel, at atomistic level, interfacial mechanisms erythritol (the most promising medium-temperature polyol PCM) two different metals (i.e., copper aluminum). co...

BACKGROUND Erythritol, a four-carbon polyol synthesized by microorganisms as an osmoprotectant, is a natural sweetener produced on an industrial scale for decades. Despite the fact that the yeast Yarrowia lipolytica has been reported since the 1970s as an erythritol producer, the metabolic pathway of this polyol has never been characterized. It was shown that erythritol synthesis in yeast occur...

Erythritol is the preferential carbon source for most brucellae, a group of facultative intracellular bacteria that cause a worldwide zoonosis. Since this polyol is abundant in genital organs of ruminants and swine, it is widely accepted that erythritol accounts at least in part for the characteristic genital tropism of brucellae. Nevertheless, proof of erythritol availability and essentiality ...

Gingivitis is one of the most common oral infections in humans. While sugar alcohols such as erythritol are suggested to have caries-preventive properties, it may also have beneficial effects in prevention of gingivitis by preventing maturation of oral biofilms. The aim of this study was to assess the effect of erythritol on the microbial ecology and the gingivitis phenotype of oral microcosms....

Erythritol utilization is a characteristic of pathogenic Brucella abortus strains. The attenuated vaccine strain B19 is the only Brucella strain that is inhibited by erythritol, so a role for erythritol metabolism in virulence is suspected. A chromosomal fragment from the pathogenic strain B. abortus 2308 containing genes for the utilization of erythritol was cloned taking advantage of an eryth...

A yeastlike fungus, probably belonging to the genus Torula, was isolated from fresh pollen and was shown to produce erythritol in yields of 35 to 40% of the sugar utilized. The ability to produce erythritol is an inherent characteristic of the isolate, but unfavorable fermentation conditions can lead to the production of glycerol at the expense of erythritol. By the use of a synthetic medium, i...

OBJECTIVE Hyperglycemia, oxidative stress, and the onset and progression of diabetic complications are strongly linked. Reduction of oxidative stress could be of utmost importance in the long-term treatment of diabetic patients. The chronic nature of the disease calls for a mode of antioxidant intake that can be sustained easily, e.g., by the diet. Erythritol, a simple polyol, could be such a c...

Bacteria of the genus Brucella have the unusual capability to catabolize erythritol and this property has been associated with their virulence mainly because of the presence of erythritol in bovine foetal tissues and because the attenuated S19 vaccine strain is the only Brucella strain unable to oxydize erythritol. In this work we have analyzed the transcriptional changes produced in Brucella b...

Citric acid and erythritol biosynthesis from pure and crude glycerol by three acetate-negative mutants of Yarrowia lipolytica yeast was investigated in batch cultures in a wide pH range (3.0-6.5). Citric acid biosynthesis was the most effective at pH 5.0-5.5 in the case of Wratislavia 1.31 and Wratislavia AWG7. With a decreasing pH value, the direction of biosynthesis changed into erythritol sy...

TO THE EDITOR: We have read with interest the recently published work by Wölnerhanssen et al. (7) entitled “Gut hormone secretion, gastric emptying, and glycemic responses to erythritol and xylitol in lean and obese subjects”. The authors demonstrated the ability of erythritol and xylitol to induce gut hormone secretion and gastric emptying retardation with no impact on glycemic and insulinemic...
