		<description><![CDATA[Researchers studying a hydrogen-producing, single-celled green algae, Chlamydomonas reinhardtii, have unmasked a previously unknown fermentation pathway that may open up possibilities for increasing hydrogen production. Normally, only a small fraction of the electrons go into generating hydrogen during fermentation. However, a major research goal has been to develop ways to increase this fraction, which would raise the potential yield of hydrogen. In the new study, researchers at the Carnegie Institution&#8217;s Department of Plant Biology, the National Renewable Energy Laboratory (NREL), and the Colorado School of Mines (CSM), examined metabolic processes in a mutant strain that was unable to assemble an active hydrogenase enzyme. The researchers expected the cell&#8217;s metabolism to compensate by increasing metabolite flow along other known fermentation pathways, such as those producing formate and ethanol as end products. Instead, the algae activated a pathway leading to the production of succinate, which was previously not associated with fermentation metabolism in C. reinhardtii. Notably, succinate, a widely used industrial chemical normally synthesized from petroleum, is included in the Department of Energy&#8217;s list of the top 12 value added chemicals from biomass.]]></description>
