Sulfate Reduction in Sediments Produces High Levels of Chromophoric Dissolved Organic Matter. [PDF]
Sci Rep, 2017 Sulfate reduction plays an important role in altering dissolved organic matter (DOM) in estuarine and coastal sediments, although its role in the production of optically active chromophoric DOM (CDOM) and a subset of fluorescent DOM (FDOM) has not been ...

Thermodynamic modelling of synthetic communities predicts minimum free energy requirements for sulfate reduction and methanogenesis. [PDF]
J R Soc Interface, 2020 Microbial communities are complex dynamical systems harbouring many species interacting together to implement higher-level functions. Among these higher-level functions, conversion of organic matter into simpler building blocks by microbial communities ...

Sulfate reduction in methanogenic bioreactors [PDF]
FEMS Microbiology Reviews, 1994 In the anaerobic treatment of sulfate-containing wastewater, sulfate reduction interferes with methanogenesis. Both mutualistic and competitive interactions between sulfate-reducing bacteria and methanogenic bacteria have been observed. Sulfate reducers will compete with methanogens for the common substrates hydrogen, formate and acetate.

Enhanced sulfate reduction with acidogenic sulfate-reducing bacteria [PDF]
Journal of Hazardous Materials, 2008 Sulfate reduction in a continuous flow, acidogenic reactor using molasses wastewater as the carbon source was studied at varying chemical oxygen demand/sulfate (COD/SO4(2-)) ratios. At a critical COD/SO4(2-) ratio of 2.7, neither COD nor sulfate were in excess for extra production of ethanol or acetate in the reactor.

Biotechnological aspects of sulfate reduction with methane as electron donor [PDF]
, 2010 Biological sulfate reduction can be used for the removal and recovery of oxidized sulfur compounds and metals from waste streams. However, the costs of conventional electron donors, like hydrogen and ethanol, limit the application possibilities.

User-friendly mathematical model for the design of sulfate reducing H2/CO2 fed bioreactors [PDF]
, 2009 The paper presents three steady-state mathematical models for the design of H2/CO2 fed gas-lift reactors aimed at biological sulfate reduction to remove sulfate from wastewater. Models 1A and 1B are based on heterotrophic sulfate reducing bacteria (HSRB),

Nitrate reduction in sulfate-reducing bacteria [PDF]
FEMS Microbiology Letters, 2016 Sulfate-reducing bacteria (SRBs) gain their energy by coupling the oxidation of organic substrate to the reduction of sulfate to sulfide. Several SRBs are able to use alternative terminal electron acceptors to sulfate such as nitrate. Nitrate-reducing SRBs have been isolated from a diverse range of environments.

Microbial processes and bacterial populations associated to anaerobic treatment of sulfate-rich wastewater [PDF]
, 2010 A pilot-scale (1.2 m3) anaerobic sequencing batch biofilm reactor (ASBBR) containing mineral coal for biomass attachment was fed with sulfate-rich wastewater at increasing sulfate concentrations. Ethanol was used as the main organic source.

Transformation of 1,1,1-trichloroethane in an anaerobic packed-bed reactor at various concentrations of 1,1,1-trichloroethane, acetate and sulfate [PDF]
, 1997 Biotransformation of 1,1,1-trichloroethane (CH3CCl3) was observed in an anaerobic packed-bed reactor under conditions of both sulfate reduction and methanogenesis. Acetate (1 mM) served as an electron donor.

Benzene oxidation coupled to sulfate reduction [PDF]
Applied and Environmental Microbiology, 1995 Highly reduced sediments from San Diego Bay, Calif., that were incubated under strictly anaerobic conditions metabolized benzene within 55 days when they were exposed initially to 1 (mu)M benzene. The rate of benzene metabolism increased as benzene was added back to the benzene-adapted sediments.
