"WebThe Crabtree Effect turns this traditional line of thinking on its end. Essentially what it says is when there is an abundance of sugar in a solution, even in the presence of oxygen, yeast may utilize sugar less efficiently (anaerobic) than they could. In other words, yeast will begin to produce CO2 and ethanol even before the oxygen is depleted. " - Crabtree effekt

WebThe results are interpreted in relation with the Crabtree effect. In Crabtree-positive yeasts, an increase in the external glucose concentration may lead to unrestricted glucose uptake by facilitated diffusion and hence, to aerobic fermentation. In contrast, Crabtree-negative yeasts may restrict the entry of glucose by their regulated H+ ... The Crabtree effect, named after the English biochemist Herbert Grace Crabtree, describes the phenomenon whereby the yeast, Saccharomyces cerevisiae, produces ethanol (alcohol) in aerobic conditions at high external glucose concentrations rather than producing biomass via the tricarboxylic acid (TCA) cycle, the usual process occurring aerobically in most yeasts e.g. Kluyveromyces spp. This phenomenon is observed in most species of the Saccharomyces, Schi…
