polyalkoholfördernde

Polyalkoholfördernde is a German adjective used in scientific texts to describe substances, organisms, or processes that promote the formation, accumulation, or presence of polyols (polyhydric alcohols) in a system.

Polyols are compounds with multiple hydroxyl groups, including glycerol, sorbitol, mannitol, and xylitol. They are widely used as sugar substitutes, humectants, stabilizers, and in chemical synthesis. In biology, factors described as polyalkoholfördernde can influence polyol levels and thereby affect osmotic balance and redox state within cells or tissues.

Biological context: In microorganisms, polyol production often serves osmoregulation and redox balancing. For example, Saccharomyces cerevisiae accumulates glycerol under high osmotic conditions. Enzymes such as glycerol-3-phosphate dehydrogenase and aldose reductases participate in polyol biosynthesis, and metabolic engineering aims to enhance flux toward specific polyols for industrial production.

Industrial relevance: Understanding polyalkoholfördernde mechanisms aids in designing fermentation and bioprocess strategies to increase yields of polyols such as sorbitol, xylitol, or glycerol. The term appears mainly in German-language literature, where it is used in discussions of metabolic pathways, osmoregulation, and process optimization related to polyol production.
