WebDec 21, 2024 · Aerobic fermentation, also referred to as the Crabtree effect in yeast, is a well-studied phenomenon that allows many eukaryal cells to attain higher growth rates at high glucose availability. Not all yeasts exhibit the Crabtree effect, and it is not known why Crabtree-negative yeasts can grow at rates comparable to Crabtree-positive yeasts. WebIn the case of K. lactis, a Crabtree-negative yeast, the growth rate of a PDC-null mutant was comparable to that of a wild-type strain,16) but the yield of a strain expressing L-LDH and lacking KlPDC1, which was reported by Porro et al.,10) was still far from the maximum theoretical yield: 0.58 lactic acid produced/ g-glucose consumed rather ...
