  abstract = {{B}oth industrial effluent discharge and the resuspension of contaminated marine sediments are important sources of trace metals in seawater which potentially affect marine ecosystems. {T}he aim of this study was to evaluate the impact of the industrial wastewaters having acidic p{H} (2-3) and containing trace metals on microbial diversity in the coastal ecosystem of the {G}ulf of {G}abes ({T}unisia, southern {M}editerranean {S}ea) subjected to resuspension events of marine sediments. {F}our trace elements ({A}s, {C}d, {U}, and {V}) were monitored during 10-day sediment resuspension experiments. {T}he highest enrichment in the seawater dissolved phase was observed for {C}d followed by {U}, {V}, and {A}s. {C}d remobilization was improved by indigenous microbial community, while {U} release was mainly abiotic. {A}cidic effluent addition impacted both trace metal distribution and microbial diversity, particularly that of the abundant phylum {B}acteroidetes. {M}embers of the order {S}aprospirales were enriched from sediment in natural seawater (initial p{H} > 8), while the family {F}lavobacteriaceae was favored by acidified seawater (initial p{H} < 8). {S}ome {F}lavobacteriaceae members were identified as dominant species in both initial sediment and experiments with acidic wastewater, in which their relative abundance increased with increasing dissolved {C}d levels. {I}t could be therefore possible to consider them as bioindicators of metal pollution and/or acidification in marine ecosystems.},
