Angewandte Chemie International Edition 52:4587-4590 (PDF) (Editor’s choice paper). Abstract: Let enzymes work! Dihydrogen was produced from xylose and water in a single reactor containing 13 enzymes. By using a novel polyphosphate xylulokinase (XK), xylose was converted to H2 and CO2 with approaching 100% of the theoretical yield. These findings suggest that cell-free biosystems could produce H2 from biomass xylose at low cost.

Abstract: Dockerin-containing triosephosphate isomerase, aldolase, and fructose 1,6-bisphosphatase were self-assembled into a static trifunctional enzyme complex through a mini-scaffoldin containing three different cohesins. The synthetic enzyme complex exhibited reaction rate enhancement compared to non-complexed three enzyme mixture at the same enzyme concentration by a factor from 10.3 to 21.1 when substrate concentration decreased from 5.0 to 0.5 mM.

90. Zhang Y-HP*, Huang WD. 2012. Constructing the electricity-carbohydrate-hydrogen cycle for sustainability revolution. Trends in Biotechnology 30: 301-306. (PDF) (Opinion). Abstract: To enhance energy utilization efficiency, we wish to suggest the electricity-carbohydrate-hydrogen (ECHo) cycle bridging among primary energies and secondary energies. Carbohydrates are sources of food, feed, liquid biofuels, and renewable materials and would be a high-density hydrogen carrier and electricity storage compound (e.g., more than 3,000 Wh/kg). One element of this ECHo cycle can be converted to another reversibly and efficiently depending on resource availability, needs, and costs. This cycle would not only supplement current and future primary energy utilization systems for facilitating electricity and hydrogen storage and enhancing secondary energy conversion efficiencies, but also address such sustainability challenges as transportation fuel production, CO2 utilization, fresh water conservation, and maintenance of a small closed ecosystem in emergency situations. Key implication : Carbohydrate could be the best solar fuel, the best long-term electricity storage compound, and sources for food, feed and renewable materials.
