  abstract = {{T}his study evaluated the anaerobic degradation of landfill leachate and sulfate reduction as a function of {COD}/({SO}42-) ratio in an upflow anaerobic fixed-bed reactor. {T}he reactor, which was inoculated with a mixed consortium, was operated under a constant hydraulic retention time ({HRT}) of 5 days. {W}e investigated the effect of {COD}/({SO}42-) ratio variation on the sulfate reduction efficiency, hydrogen sulfide production, chemical oxygen demand ({COD}) removal, conductivity, and p{H} variation. {T}he best reactor performance, with significant sulfate reduction efficiency and {COD} removal efficiency of 91% and 87%. respectively, was reached under a {COD}/({SO}42-) ratio of 1.17. {U}nder these conditions, microscopic analysis showed the abundance of vibrios and rod-shaped bacterial cells. {T}wo anaerobic bacteria were isolated from the reactor sludge. {P}hylogenetic studies performed on these strains identified strain {A}1 as affiliated to {C}lostridium genus and strain {H}1 as a new species of sulfate-reducing bacteria affiliated to the {D}esulfovibrio genus. {T}he closest phylogenetic relative of strain {H}1 was {D}esulfovibrio desulfuricans, at 96% similarity for partial 16{S} {RNA} gene sequence data. {P}hysiological and metabolic characterization was performed for this strain.},
