  abstract = {{A}naerobic biotechnology using sulfate-reducing bacteria ({SRB}) is a promising alternative for reducing long-term stockpiling of phosphogypsum ({PG}), an acidic (p{H} similar to 3) by-product of the phosphate fertilizer industries containing high amounts of sulfate. {T}he main objective of this study was to evaluate, for the first time, the diversity and ability of anaerobic marine microorganisms to convert sulfate from {PG} into sulfide, in order to look for marine {SRB} of biotechnological interest. {A} series of sulfate-reducing enrichment cultures were performed using different electron donors (i.e., acetate, formate, or lactate) and sulfate sources (i.e., sodium sulfate or {PG}) as electron acceptors. {S}ignificant sulfide production was observed from enrichment cultures inoculated with marine sediments, collected near the effluent discharge point of a {T}unisian fertilizer industry ({S}fax, {T}unisia). {S}ulfate sources impacted sulfide production rates from marine sediments as well as the diversity of {SRB} species belonging to {D}eltaproteobacteria. {W}hen {PG} was used as sulfate source, {D}esulfovibrio species dominated microbial communities of marine sediments, while {D}esulfobacter species were mainly detected using sodium sulfate. {S}ulfide production was also affected depending on the electron donor used, with the highest production obtained using formate. {I}n contrast, low sulfide production (acetate-containing cultures) was associated with an increase in the population of {F}irmicutes. {T}hese results suggested that marine {D}esulfovibrio species, to be further isolated, are potential candidates for bioremediation of {PG} by immobilizing metals and metalloids thanks to sulfide production by these {SRB}.},
