Ethanol: Research on Ethanol Reported by Scientists at University of Chile

Researchers detail in ""Glucose and ethanol-dependent transcriptional regulation of the astaxanthin biosynthesis pathway in Xanthophyllomyces dendrorhous"," new data in Ethanol. According to the authors of recent research from Santiago, Chile, "The yeast Xanthophyllomyces dendrorhous is one of the most promising and economically attractive natural sources of astaxanthin. The biosynthesis of this valuable carotenoid is a complex process for which the regulatory mechanisms remain mostly unknown."

"Several studies have shown a strong correlation between the carbon source present in the medium and the amount of pigments synthesized. Carotenoid production is especially low when high glucose concentrations are used in the medium, while a significant increase is observed with non-fermentable carbon sources," wrote A. Marcoleta and colleagues, University of Chile.

The researchers concluded: "However, the molecular basis of this phenomenon has not been established."

Marcoleta and colleagues published their study in Bmc Microbiology ("Glucose and ethanol-dependent transcriptional regulation of the astaxanthin biosynthesis pathway in Xanthophyllomyces dendrorhous". Bmc Microbiology, 2011;11():190).
