(Submitter supplied) Geobacter sulfurreducens was originally considered a strict anaerobe. However, this bacterium was later shown to not only tolerate but also to use oxygen as terminal electron acceptor. Research performed has so far only revealed the general ability of G. sulfurreducens to reduce oxygen, but the oxygen consumption rate has not been quantified, nor has evidence been provided as to how the bacterium achieves oxygen consumption. more...

(Submitter supplied) Previous analysis of gene transcript levels of Geobacter species in groundwater during in situ bioremediation of a uranium-contaminated aquifer detected expression of genes encoding superoxide dismutase (sodA) and cytochrome d ubiquinol oxidase (cydA), proteins known to be involved in the response to oxidative stress in other microorganisms. In order to further elucidate gene expression patterns that could be attributed to oxygen exposure, G. more...

(Submitter supplied) Geobacter sulfurreducens is capable of reducing Pd(II) to Pd(0) using pyruvate as an electron donor; however, the biochemical and genetic mechanisms involved in this process have not been described. In this work, we carried out transcriptome profiling analyes to identify genes involved in Pd(II) reduction in this bacteria. Our results showed that 254 genes were upregulated while 142 were downregulated during Pd(II) reduction. more...

(Submitter supplied) In this experiment two strains were compared. The control strain was the wild type strain containing the plasmid, pCD341. pCD341 is an inducible expression vector, a plasmid which can be used to make a bacterium produce a protein of interest. It is called inducible, because the protein of interest will only be produced if an inducer, in this case, IPTG, is present. In the control strain pCD341 is "empty", meaning the gene encoding the protein of interest has not been inserted into the vector, so when you add IPTG nothing will be produced. more...

(Submitter supplied) There is a wide diversity of potential applications for direct electron transfer from electrodes to microorganisms, which might be better optimized if the mechanisms for this novel electrode-biofilm interaction were better understood. Geobacter sulfurreducens is one of the few microorganisms available in pure culture that is known to be capable of directly accepting electrons from a negatively poised electrode. more...
