TL;DR: The current understanding of antimony biochemistry and biogeochemistry is roughly equivalent to where that of arsenic was some 20 years ago, indicating the possibility of future discoveries with regard to the ability of microorganisms to conserve energy for their growth from antimony redox reactions and the isolation of new species of “antimonotrophs.”

TL;DR: Comparative proteomics and reverse transcriptase-PCR analysis of Sb(III)-oxidizing bacterium Agrobacterium tumefaciens GW4 revealed an oxidoreductase (anoA) is widely distributed in microorganisms, including at least some documented to be able to oxidize S b(III).

TL;DR: Thin-layer chromatography and gas chromatography-mass spectrometry analysis suggested the presence of arsenolipids in membranes, presumably as part of the bilayer structure of the cell membrane and replacing Pi under Pi-limiting conditions.

TL;DR: To elucidate the mechanism of HNAD in co-strains, quantitative PCR was carried out and the results showed that the napA2, narG and ppk genes in the strains were significantly upregulated under the co-cultured conditions and provided an explanation for the nitrogen and phosphate removal.

TL;DR: The data reveal a novel mechanism that bacterial Sb(III) oxidation is associated with abiotic (cellular H2O2) and biotic (AnoA and AioAB) factors and Sb’s oxidation process consumes cellular H2 O2 which contributes to microbial detoxification of both Sb (III) and cellular H 2O2.
