Science Daily November 5, 2019 Bacteria don’t have mouths, so they need another way to bring their fuel into their bodies. Researchers at Washington University have shown how a naturally occurring bacteria (a strain of Rhodopseudomonas palustris TIE-1) builds a conduit to accept electrons across its outer membrane. The bacteria rely on an iron-containing helper molecule called a deca-heme cytochrome c. By processing this protein, TIE-1 can form an essential bridge to its electron source. According to the researchers the study will aid in designing a bacterial platform where bacteria can feed on electricity and carbon dioxide to produce value-added […]
