••
TL;DR: In this article, the influence of the degree of ion exchange resin cross-linking and size on the resolution and purity of products separated by ligand exchange liquid chromatography was studied with mannitol-sorbitol and arabitol-xylitol mixtures.

TL;DR: The formation of 10 g polyols/L (glycerol, arabitol, xylitol) during L-lactic acid synthesis by Rhizopus arrhizus was observed, resulting in a subsequent rise in the lipid content of the mycelium.
Abstract: The formation of 10 g polyols/L (glycerol, arabitol, xylitol) during L-lactic acid synthesis byRhizopus arrhizus was observed. Consumption of polyols after glucose exhaustion was discovered resulting in a subsequent rise in the lipid content of the mycelium. Lactate utilization was not detected.

01 Jan 1992TL;DR: In this article, the trisaccharide raffinose was found to increase in mycorrhizal and non-mycorrhize roots of Norway spruce when the plants were kept at low temperature and a short photoperiod.
Abstract: Both mycorrhizal and non mycorrhizal roots of Norway spruce accumulated the trisaccharide raffinose when the plants were kept at low temperature and a short photoperiod. More raffinose was accumulated at low light intensities (18μE m-2s-1) than at high light intensities (300μE m-2s-1). Conversely, the level of sucrose, the main soluble carbohydrate present in the roots, increased in mycorrhizal and non mycorrhizal roots at the high light intensities whilst it decreased slightly at low light intensities during the cold treatment. The main fungal soluble carbohydrates found in the mycorrhizal roots were trehalose, arabitol and mannitol. Under low light intensities in the cold the level of arabitol decreased, whereas the levels of trehalose and mannitol remained constant and slightly increased, respectively. However, under high light intensities, the amounts of all the fungal soluble carbohydrates increased, particularly arabitol and trehalose.

TL;DR: In this paper, the aldol reaction of lithium enolates of tetronates with (R)-2,3-O-cyclohexylideneglyceraldehyde afforded the chelation controlled products stereoselectively.
Abstract: The aldol reaction of lithium enolates of tetronates with (R)-2,3-O-cyclohexylideneglyceraldehyde afforded the chelation controlled products stereoselectively The conversion of the aldol products into arabitol and ribitol was also described
