Optimal yeast strains for the production of fuels and chemicals from lignocellulosic biomass
… the bioprocess must use non-food plants, called cellulosic biomass. Such renewable biomass, however, contains both hexose and pentose sugars, mainly glucose and xylose, which are not efficiently fermented by microbes. Despite numerous efforts for improving xylose fermentation during the last two …
