Xylose utilization remains the primary bottleneck in fully using the renewable plant biomass. In a Nature Scientific Reports paper entitled, “Evolved hexose transporter enhances xylose uptake and glucose/xylose co-utilization in Saccharomyces cerevisiae,” Biological Systems & Engineering Division researchers at Joint BioEnergy Institute (JBEI) Amanda Reider Apel and Aindrila Mukhopadhyay report the discovery and characterization of a yeast sugar transporter variant with superior Vmax (uptake rates) for xylose. This discovery will be valuable in developing biomanufacturing strains that can use the full set of sugars generated from plant biomass. Read more on the JBEI website.
