Characterization using X-ray photoelectron spectroscopy and X-ray power diffraction analyses confirmed that most removed Te(IV) was reduced to elemental Te(0) deposits, while ion chromatogram analysis showed that most S(0) was oxidized to sulfite and sulfate. High-throughput 16S rRNA gene sequencing indicated that the Te(IV) reduction coupled to S(0) oxidation was mediated synergistically by a microbial consortia with S(0)-oxidizing bacteria (Thiobacillus) to generate volatile fatty acids as metabolites and Te(IV)-reducing bacteria (Rhodobacter) to consume formed volatile fatty acids to yield Te(0). The synergy between these two strains presents a novel bioremediation consortium to efficiently treat Te(IV) wastewaters. ? 2021 Elsevier LtdElemental SulfurGroundwaterMicrobial reductionTe(IV)BacteriaBioremediationChromatographic analysisMetabolitesRNATellurium compoundsVolatile fatty acidsWastewater treatmentX ray photoelectron spectroscopyBioreductionsDiffraction analysisElectron donorsElemental sulphurIon chromatogramPower diffractionReactions ratesX-ray powerSulfur compoundsRNA 16Ssulfatesulfitetelluriumvolatile fatty acidsulfurbacteriumbioremediationdetection methodelectronmicrobial activityreaction ratereductionArticlecontrolled studygene sequenceion chromatographymicrobial communitymicrobial consortiummunicipal wastewaternonhumanoxidationreduction (chemistry)RhodobacterRNA sequencingThiobacilluswaste water managementX ray diffractionX ray photoemission spectroscopygeneticsoxidation reduction reactionElectronsOxidation-ReductionRNA, Ribosomal, 16SSulfatesSulfur[SDGs]SDG11journal article10.1016/j.biortech.2021.125896346490592-s2.0-85116940397
