[The effect of glucose on the fatty acid level in Saccharomyces cerevisiae and Schwanniomyces occidentalis cells].
The influence of glucose on fatty acid contents in the cells of yeast Saccharomyces cerevisiae and Schwanniomyces occidentalis has been studied. It was shown that fatty acid contents in Schw. occidentalis was enhanced with the increase of glucose concentration in the medium. The increase of glucose concentration in the medium during respiro-fermentative growth phase reduces the level of C18 in unsaturated fatty acids of S. cerevisiae; the increase of fatty acids content in total lipids and nonetherified fatty acids was observed under the same conditions in the respiratory phase. It was established that during the growth of S. cerevisiae in the medium with 0.1% glucose the level of nonetherified fatty acids was higher and with 4% glucose--lower in comparison with Schw. occidentalis. The correlation of nonetherified and etherified fatty acid levels in S. cerevisiae is higher in comparison with Schw. occidentalis grown under the same conditions.
