Purple phototrophic bacteria could use certain kinds of wastewater, along with electric current, to produce valuable products like hydrogen without much waste!
Thanks to Dr. Ioanna Vasiliadou for her contribution!
Microbe of the episode
This versatility makes them very interesting candidates for industrial biotechnology applications. These bacteria can take in various combinations of nutrients and produce a number of different valuable products, including protein-rich feed, bioplastics, and biofuels such as hydrogen gas.
Today's study shows they can also take up electrons directly to help make their biofuel production process even more environmentally sustainable.
