Ethanol stimulation of oxidative metabolism in Euglena gracilis

Research output: Contribution to journalArticle


Euglena gracilis, a flagellate protozoan, utilizes acetate and ethanol as energy and carbon sources. The acetate metabolism of Euglena grown on ethanol differs from that grown on acetate. Ethanol-grown cells have a rate of acetate oxidation at pH 7.0 lower than that of acetate-grown cells1. However, ethanol-grown cells incubated in the presence of acetate for about 80 min. often adapt to acetate, taking on characteristics similar to those of acetate-grown cells1,2. Thus, it was considered of interest to determine the respiration of Euglena in the presence of both acetate and ethanol.
