WebJun 1, 2014 · The Crabtree effect is the aerobic production of ethanol in the presence of repressing levels of glucose. This effect is stronger in strains growing on glucose and is reduced when the same strain is grown in a carbon … 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.

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… WebMar 1, 2010 · The Crabtree effect is still little known and relates as well to prokaryotic cells (bacteria) as to eukaryotes (fungi and mammals).
