Shewanella oneidensis and Extracellular Electron Transfer to Metal Oxides

Rapid construction of a whole-genome transposon insertion collection for Shewanella oneidensis by Knockout Sudoku

“…6d). Consistent with reports that disruption of the mtrDEF operon, paralogous to the mtrCAB operon, has no role in Fe(III) reduction18, disruptions here had no discernible impact on AQDS reduction (Fig. 6a).…”

“…However, despite intense research, the functions of over half of its genes remain unknown13 and fundamental discoveries about its nature continue to be made1214. Although the centrality of the MtrABC complex in EET is well established15, debate continues about the full complement of proteins used in this process, particularly in electron transfer from the inner membrane, across the periplasm, to the outer membrane16171819. There remains an ongoing need for the development of new, highly accessible tools for the genetic manipulation and characterization of S. oneidensis 1820 and the menagerie of esoteric microorganisms found in nature that offer unique capabilities to biological engineering and medicine.…”

Rapid production of Pd nanoparticle by a marine electrochemically active bacterium Shewanella sp. CNZ-1 and its catalytic performance on 4-nitrophenol reduction

“…Among them, members of genus Shewanella are famous members of electrochemically active bacteria (EAB) that capable of using various metals/metalloids as terminal electron acceptors for their anaerobic respiration. 23 It's reported that members of genus Shewanella are widely used to synthesize various metal NPs with great potentials for practical applications. [22][23][24] Therefore, studies on production process and mechanism of Pd-NPs through genus Shewanella are attracting more and more attentions.…”

“…However, despite intense research, the functions of over half of the genes in the S. oneidensis genome remain unknown 12 and fundamental discoveries about the nature of the organism continue to be made 11,13 . Although the centrality of the MtrA, MtrB and MtrC cytochromes in EET is well established 14 , debate about the full complement of proteins used in EET, particularly in the transfer of electrons from the inner membrane across the periplasmic gap to the outer membrane continues [15][16][17] . There remains an ongoing need for the continued development of new tools for the genetic manipulation and characterization of S. oneidensis, as well as other electroactive microbes and esoteric microorganisms 1,7,18 .…”
