Abstract

The burning of fossil fuels is responsible for 73% of the emission of CO2 in the atmosphere, intensifying the greenhouse effect and global warming. The production of biofuels from lignocellulosic (LC) waste can supply the energy matrix in the near future. However, the fermentation of LC hydrolysates encompasses many scientific and technological challenges. Pretreatment processes generate a variety of molecules (furan derivatives, phenolic compounds and organic acids) that act as inhibitors of microbial metabolism, and thus reduce the efficiency of fermentation. In this context, this research proposal aims to investigate the effect of lignocellulosic inhibitors on lactic acid bacteria, normally present in industrial fermentation processes. Therefore, a quantitative and well defined physiological characterization, in the presence of lignocellulosic inhibitors, will be performed. Ultimately, we intend to understand how different strains of contaminating bacteria respond to lignocellulosic inhibitors. (AU)
