Cellulose and starch have the same chemical formula Zhang said. The difference is in their chemical linkages.
Our idea is to use an enzyme cascade to break up the bonds in cellulose enabling their reconfiguration as starch.

The biocatalysts used to release the hydrogen are a group of enzymes artificially isolated from different microorganisms that thrive at extreme temperatures some
Even more appealing this reaction occurs at low temperatures generating hydrogen energy that is greater than the chemical energy stored in xylose and the polyphosphate.
That means that low-temperature waste heat can be used to produce high-quality chemical energy hydrogen for the first time. Other processes that convert sugar into biofuels such as ethanol and butanol always have energy efficiencies of less than 100 percent resulting in an energy penalty.

Hirasaki Rice's A j. Hartsook Professor of Chemical and Biomolecular engineering said employing waste heat is just one example of a number of ways that Rice's team is looking to improve upon a tried-and-true technology for CO2 capture.
That technology--a two-phase chemical process--has been used for decades to remove naturally occurring CO2 from natural gas.
To test this idea Warudkar used a software package that's commonly used to model industrial chemical processes.
One variable he tested was tailoring the chemical formulation of the liquid amine solution. Other variables included the type of steam used and the size and pressure of the reactor--the chamber where the flue gas flows past the amine solution.
Study co-authors include Michael Wong professor of chemical and biomolecular engineering and of chemistry and Ken Cox professor in the practice of chemical and biomolecular engineering.
A typical BECCS system converts woody biomass grass and other vegetation into electricity chemical products or fuels such as ethanol.
The researchers'results reported this month in the American Chemical Society journal Environmental science and Technology are the latest in a long effort to understand the environmental aspects of antibiotic resistance which threatens decades of progress in fighting disease.
