Technical Abstract: The microbial fermentation of biomass derived sugar mixtures is one of the barriers to the overall economic conversion process from lignocellulosic biomass to fuels and chemicals. Although the supply and characteristics of feedstocks vary, biomass hydrolysates usually contain mixed sugars, organic acids, sugar degradation products, and polyphenolics. Different pretreatment and fermentation processes are being developed to minimize the effect of fermentation inhibition by some of the compounds present in hydrolysates. New robust microbes need to be developed to efficiently convert the mixed sugars in hydrolysates into ethanol and value added products. In this paper, we discuss progress and challenges in exploring Gram-positive bacteria as second generation biocatalysts for ethanol and lactate production. Results will be valuable to researchers designing improved biocatalysts for converting biomass to bioenergy.
