Growth of sulfate-reducing bacteria with sulfur as electron acceptor
Archives of Microbiology, 1977In addition to three new isolates, six strains of representative species of sulfate-reducing bacteria were tested for their capacity to use elemental sulfur as an electron acceptor for growth. There was good growth and sulfide production by strain Norway 4 and the three isolates, two of which had been enriched with sulfur flower and one isolated from a

Polysulfide as a possible substrate for sulfur-reducing bacteria
Archives of Microbiology, 1993Because of its low solubility it is unlikely that elemental sulfur serves as the direct substrate for sulfur-reducing bacteria. To test the hypothesis that polysulfide may represent a soluble intermediate of sulfur reduction, the maximal polysulfide concentrations formed from elemental sulfur in aqueous sulfide solutions were measured at near neutral ...

The marine green sulfur bacterium Chlorobium vibrioforme strain 1930 produced H2 and elemental sulfur from sulfide or thiosulfate under N limitation in the light. H2 production depended on nitrogenase and occurred only in the absence of ammonia. Methionine sulfoximine, an inhibitor of glutamine synthetase, prevented the switch-off by ammonia.

A survey of EPR-detectable components in sulfur-reducing bacteria
Biochimica Et Biophysica Acta - Bioenergetics, 1983Abstract A survey was made of components of sulfur-reducing bacteria that can be detected by EPR spectroscopy. To this purpose, whole cells were examined and a membrane and cytoplasm fraction obtained by centrifugation at 120 000 × g after cell lysis by suitable procedures.

Sulfur-oxidizing bacteria (SOB) and sulfate-reducing bacteria (SRB) inhabit oilfield production systems. Sulfur oxidation driven by SOB and dissimilatory sulfate reduction driven by SRB play important roles in sulfur cycle of oil reservoirs. More importantly, hydrogen sulfide produced by SRB is an acidic, flammable, and smelly toxic gas associated with

Sulfur isotope fractionation by sulfate‐reducing bacteria in corrosion products
Biofouling, 1993Sulfur isotope fractionation was demonstrated in preliminary studies of corrosion products resulting from the activities of sulfate‐reducing bacteria within biofilms on copper surfaces. 32S accumulated in corrosion products, 34S was concentrated in the culture medium.

Growth yields of green sulfur bacteria in mixed cultures with sulfur and sulfate reducing bacteria
Archives of Microbiology, 19781. Dry weight yields from mixed cultures ofProsthecochloris aestuarii orChlorobium limicola with the sulfur reducingDesulfuromonas acetoxidans were determined on different growth limiting amounts of acetate, ethanol or propanol. The obtained yields agreed well with values predicted from stoichiometric calculations. 2.

[Sulfate-reducing bacteria in reservoirs of the Yavoriv sulfur field].
Mikrobiolohichnyi zhurnal (Kiev, Ukraine : 1993), 2007Fifteen cultures of bacteria which perform dissimilation sulfate reduction have been isolated from the reservoirs of the Yavoriv sulfur deposit. Electron-microscopic investigations have shown that the cells of all cultures are of vibroid, spiral and bacillary form. They form no spores.

The spent caustic wastewater from the oxidation of sulfide present in offshore natural gas production mainly comprises thiosulfate and sulfate. A biocatalytic process, employing phototrophic green sulfur bacteria in symbiosis with sulfate-reducing bacteria, is described in this paper for the production of sulfur from the spent caustic wastewater, with ...

Role of sulfur-reducing bacteria in a wetland system treating acid mine drainage
Science of The Total Environment, 2008This report describes a twenty month case study of a successive alkalinity producing system (SAPS) treating a strong acid mine drainage (AMD) source in Coshocton County, Ohio. Prior to the commencement of the project, a large volume of black amorphous sludge had accumulated in several of the constructed wetlands. The sludge was found to be 43% organic,
