The metabolic profile of industrial sugarcane fermentation process

Brazil is the world’s largest producer of ethanol fuel from sugarcane fermentation. One of the main reasons ensuring this success is the selection of improved Saccharomyces cerevisiae strains, as large-scale industrial fermentation process occurs in a non-aseptic environment, resulting in the proliferation of various contaminant microorganisms, leading to relevant losses. The identification and quantification of contaminating molecules produced by microorganisms could help to minimize the stress conditions for yeast cells during the industrial fermentation. The aim of this work is to identify contaminating molecules through the characterization of the metabolic profile in the fermentation tanks, along the industrial sugarcane fermentation process.
