Sino-Dan international joint research team discovered a new mechanism for cable bacteria-driven biogeochemical cycling in sediments
Recently, the Institute of Microbiology, Guangdong Academy of Science, in collaboration with the School of Environmental Science and Engineering, Sun Yat-sen University, and the Center for Electromicrobiology of Aarhus University (Denmark), have made a new discovery in the study of electroactive microorganism-driven element cycling in sediments namely Electric Oxygen Extension (EOE). The EOE model proposes that overlaying water oxygen fluctuation affects distant anoxic sediment biogeochemistry mediated by cable bacteria, a recently discovered centimeter-long electro-conductive microbe. This study was published on the ISME journal entitled “Cable bacteria extend the impacts of elevated dissolved oxygen into anoxic sediments” on Jan. 21st, 2021 (https://doi.org/10.1038/s41396-020-00869-8).

ES&T: Extracellular Electron Shuttling Mediated by Soluble?c-Type Cytochromes Produced by?Shewanella oneidensis?MR-1
Dissimilatory metal-reducing bacteria can oxidize intracellular organic compounds coupled with transferring electrons to terminal electron acceptors through extracellular electron transfer. These processes play a key role in degradation of organic pollutants and migration/transformation of heavy metals. Three pathways of extracellular electron transfer by dissimilatory metal reducing bacteria have been well recognized, including direct contact between the outer membrane and electron acceptors, electron shuttling, and nanowire-mediated electron transfer. While it is well known that Shewanella species interacts with electron acceptors primarily via flavins as soluble electron shuttles, it is unclear whether there are other processes of transferring electrons to the terminal electron acceptors.
