WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

Researchers at Washington University in St. Louis have discovered a new way to train microbes to make n -butanol. Here we have harnessed the power of microbes to convert carbon dioxide into value-added multi-carbon compounds in a usable biofuel. We hope that it can be a steppingstone for future sustainable solar fuel production.
