[Activities of gluconeogenetic enzymes in the yeast Candida maltosa during growth on glucose or ethanol].
The activities of fructose-1,6-bisphosphatase, malate dehydrogenase and PEP carboxykinase were tested during discontinuous growth of the n-alkane-assimilating yeast Candida maltosa on glucose or ethanol. As expected, the highest activities of the enzymes were measured in the early log phase of growth on ethanol and the lowest in the early log phase of growth on glucose. However, the differences in the activities are much smaller than in Saccharomyces cerevisiae and other yeasts under similar conditions. Therefore, we conclude that catabolite repression does not play an essential role in the control of gluconeogenesis in Candida maltosa.
