Lead removal through biological sulfate reduction process
Bioresource Technology, 2007The feasibility of lead removal through biological sulfate reduction process with ethanol as electron donor was investigated. Sulfide-rich effluent from biological process was used to remove lead as lead sulfide precipitate. The experiments were divided into two stages; Stage I startup and operation of sulfidogenic process in a UASB reactor and Stage ...

Dissimilatory Sulfate Reduction, Energetic Aspects
1981Several strict anaerobic prokaryotes are capable of using sulfate as electron acceptor for catabolic oxidation processes. In doing so sulfate is reduced to H2S (Fig. 1). Respiration with sulfate as acceptor is termed dissimilatory sulfate reduction, bacteria capable of sulfate respiration are classifled as sulfate-reducing bacteria.

A kinetic study on bacterial sulfate reduction
Bioprocess and Biosystems Engineering, 2013The activity of anaerobic sulfate reduction was studied using sulfate-reducing bacteria isolated from the water produced from a Brazilian oil reservoir. The effects of the initial sulfate concentration on the anaerobic sulfate reduction and sulfide generation kinetics were investigated. The redox potential, the biomass solution content, and the sulfate

Sulfate reduction below the sulfate–methane transition in Black Sea sediments
Deep Sea Research Part I: Oceanographic Research Papers, 2011Abstract A sudden increase in salinity about 7000 years ago caused a shift in the deposited sediments of the Black Sea from limnic to brackish-marine. Due to the development of an anoxic deep water basin and a relatively high sulfate concentration, organic matter is mineralized primarily through sulfate reduction in modern Black Sea sediments ...

Sulfate reduction via a trisulfide
Science, 2015Microbial Metabolism Microorganisms can respire sulfur compounds in the absence of oxygen, eventually leading to the production of hydrogen sulfide. This ancient metabolism is common in modern anoxic environments, but the enzymatic pathways aren't yet fully resolved. Through in vivo and in vitro experiments, Santos et al.

Dissimilatory Sulfate Reduction, Mechanistic Aspects
1981Dissimilatory sulfate-reducing bacteria, belonging to the genera Desulfovibrio and Desulfotomaculum can carry out the process of anaerobic respiration by utilizing inorganic sulfate as a terminal electron acceptor. The overall process of dissimilatory sulfate reduction may be considered to occur in two phases.

Soil auto-epuration in Guadeloupe: sulfate reduction
Agronomie, 2002Ce papier se propose d'evaluer le pouvoir auto-epurateur des 2 grands types de sols guadeloupeens (vertisols calcaires et sols acides ferralitiques) soumis ou non au prealable a des apports repetes d'effluents de distilleries agricoles ou industrielle. Les effluents se caracterisent par de fortes charges organiques et par la presence de sulfates.
