Inhibition of microbial sulfate reduction in a flow-through column system by (per)chlorate treatment. [PDF]

, 2014
Microbial sulfate reduction is a primary cause of oil reservoir souring. Here we show that amendment with chlorate or perchlorate [collectively (per)chlorate] potentially resolves this issue. Triplicate packed columns inoculated with marine sediment were

Effect of free phosphine on sulfate reduction

浙江大学学报. 农业与生命科学版, 2008
The effects of free phosphine on growth and metabolism of sulfate-reducing bacteria were investigated using batch experiment. The results show that when COD/SO42- ratio was 1.0, high phosphine level had an adverse effect on sulfate reduction.

Usage of metals as the terminal electron acceptors by the sulfate-reducing bacteria

Біологічні студії, 2009
The review briefly describes the toxic effects of heavy metals towards microorganisms and the resistance mechanisms to heavy metals. The processes of fermentative and non-fermentative reduction of oxidized metals forms by the sulfate-reducing bacteria ...

Influence of Phosphorus and Cell Geometry on the Fractionation of Sulfur Isotopes by Several Species of Desulfovibrio during Microbial Sulfate Reduction

Frontiers in Microbiology, 2017
We investigated the influence of organic substrates and phosphate concentration on the rates of dissimilatory microbial sulfate reduction and the 34S/32S isotopic fractionation produced by several Desulfovibrio species.

Thermophilic Sulfate Reduction in Hydrothermal Sediment of Lake Tanganyika, East Africa [PDF]

, 1994
In environments with temperatures above 60 degrees C, thermophilic prokaryotes are the only metabolically active life-forms. By using the (SO42-)-S-35 tracer technique, we studied the activity of sulfate-reducing microorganisms (SRM) in hot sediment from

Geoengineering: Whiter skies? [PDF]

, 2012
One proposed side effect of geoengineering with stratospheric sulfate aerosols is sky whitening during the day and afterglows near sunset, as is seen after large volcanic eruptions.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Contrasting kinetics of arsenic release from As-bearing ferrihydrite coprecipitates by distinct sulfate-reducing bacteria

Ecotoxicology and Environmental Safety
Microbial sulfate reduction plays key roles in arsenic (As) biotransformation and release in groundwater aquifers; however, influences by distinct sulfate-reducing strains on the transformation of As-bearing iron (oxyhydr)oxide under different sulfate ...

Electron acceptors for sulphate-reducing bacteria Desulfomicrobium sp. in the process of oxidation of organic compounds

Біологічні студії, 2013
In the presence of sulfate in the medium? sulfate-reducing bacteria Desulfomicro­bium sp. use it as a final electron acceptor with it’s reduction to hydrogen sulfide. Except sulfate, bacteria Desulfomicrobium sp.
