Advanced Biofuels are high-energy liquid transportation fuels derived from: low nutrient input/high per acre yield crops; agricultural or forestry waste; or other sustainable biomass feedstocks including algae.  The key word is “sustainable.”
A technical definition that …

Cellodextrin Transport in Yeast for Improved Biofuel Production

Submitted by on October 18, 2010 – 3:51 pmNo Comment

by Jonathan M. Galazka,  Chaoguang Tian,  William T. Beeson, Bruno Martinez, N. Louise Glass, Jamie H. D. Cate    (Science) Fungal degradation of plant biomass may provide insights for improving cellulosic biofuel production. We show that the model cellulolytic fungus Neurospora crassa relies on a high-affinity cellodextrin transport system for rapid growth on cellulose. Reconstitution of the N. crassa cellodextrin transport system in Saccharomyces cerevisiae promotes efficient growth of this yeast on cellodextrins. In simultaneous saccharification and fermentation experiments, the engineered yeast strains more rapidly convert cellulose to ethanol when compared with yeast lacking this system. READ MORE
