Quantitative proteomic analysis of the Saccharomyces cerevisiae industrial strains CAT-1 and PE-2

The importance of the present works emerges from the necessity to better understand the peculiar biological features from two important bioethanol industrial strains of Saccharomyces cerevisiae during batch fermentation. We applied an iTRAQ-based quantitative proteomics analysis to compare these two important strains during batch fermentation and identified possible features involved in the fermentation performance. The results provided by this work will serve as an initial framework for future investigations on the biology of both strains.
