Optimizing pentose sugar utilization in Escherichia coli for the production of biofuels
The hydrolysis of biomass yields a sugar mixture consisting mainly of glucose, arabinose and xylose. Effective metabolism of all sugars in biomass by a microorganism is regarded as essential for commercial biofuel production. However, two of the major challenges that we are currently faced with are …

Discovery and characterization of pentose-specific transporters in Saccharomyces cerevisiae
… from lignocellulosic feedstock. Unfortunately, pentose sugars, which make up to 30% of lignocellulose, cannot be utilized by S. cerevisiae. Pentoses can only enter yeast cells through hexose transporters, which have two orders of magnitude lower affinities for pentose sugars. Additionally, …

Pathway optimization and engineering for biofuel production
… One such significant pathway is the cellobiose utilization pathway, identified as a promising route for efficient biomass utilization. Here we describe the simultaneous optimization of the β-glucosidase (gh1-1) and the cellodextrin transporter (cdt-1) through directed evolution of the pathway. …
