Galvanic interpretation of self‐potential signals associated with microbial sulfate‐reduction [PDF]

open access: yesJournal of Geophysical Research: Biogeosciences, 2007
We have evaluated the usefulness of the self‐potential (SP) geophysical method to track the onset and location of microbial sulfate‐reduction in saturated sediments during organic carbon amendment. Following stimulation of sulfate‐reducing bacteria (SRB) by addition of lactate, anomalous voltages exceeding 600 mV correlated in space and time with the ...

A microbial method for improving salt swelling behavior of sulfate saline soil by an experimental study

open access: yesAlexandria Engineering Journal, 2019
Services of soil environment system and safety production of pavements and railways are seriously affected and threatened by salt swelling behavior of sulfate saline soil.

Biogeochemical dynamics and microbial community development under sulfate- and iron-reducing conditions based on electron shuttle amendment.

open access: yesPLoS ONE, 2021
Iron reduction and sulfate reduction are two of the major biogeochemical processes that occur in anoxic sediments. Microbes that catalyze these reactions are therefore some of the most abundant organisms in the subsurface, and some of the most important.

Microbial processes and bacterial populations associated to anaerobic treatment of sulfate-rich wastewater [PDF]

open access: yes, 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.

Microbial Response to Experimentally Controlled Redox Transitions at the Sediment Water Interface. [PDF]

open access: yesPLoS ONE, 2015
The sediment-water interface of freshwater lakes is characterized by sharp chemical gradients, shaped by the interplay between physical, chemical and microbial processes.

Microbial metal resistance and metabolism across dynamic landscapes: high-throughput environmental microbiology. [PDF]

open access: yes, 2017
Multidimensional gradients of inorganic compounds influence microbial activity in diverse pristine and anthropogenically perturbed environments. Here, we suggest that high-throughput cultivation and genetics can be systematically applied to generate ...

Effects of Sulfate Reduction on Trichloroethene Dechlorination by Dehalococcoides-Containing Microbial Communities [PDF]

open access: yesApplied and Environmental Microbiology, 2017
ABSTRACT In order to elucidate interactions between sulfate reduction and dechlorination, we systematically evaluated the effects of different concentrations of sulfate and sulfide on reductive dechlorination by isolates, constructed consortia, and enrichments containing Dehalococcoides sp.

Geochemistry and Microbiology Predict Environmental Niches With Conditions Favoring Potential Microbial Activity in the Bakken Shale

open access: yesFrontiers in Microbiology, 2020
The Bakken Shale and underlying Three Forks Formation is an important oil and gas reservoir in the United States. The hydrocarbon resources in this region are accessible using unconventional oil and gas extraction methods, including horizontal drilling ...

Selection for novel, acid-tolerant Desulfovibrio spp. from a closed Transbaikal mine site in a temporal pH- gradient bioreactor [PDF]

open access: yes, 2017
Almost all the known isolates of acidophilic or acid-tolerant sulphate-reducing bacteria (SRB) belong to the spore-forming genus Desulfosporosinus in the Firmicutes.

Microbiologically influenced corrosion of steel in coastal surface seawater contaminated by crude oil

open access: yesnpj Materials Degradation, 2022
Petroleum-hydrocarbons spilt in surface seawater may pose potential threats to the corrosion of steel infrastructures. We show that crude oil accelerated steel corrosion mainly by accelerating microbiologically influenced corrosion (MIC).
