Uncovering Key Metabolic Determinants of the Drug Interactions Between Trimethoprim and Erythromycin in Escherichia coli

open access: yesFrontiers in Microbiology, 2021
Understanding interactions between antibiotics used in combination is an important theme in microbiology. Using the interactions between the antifolate drug trimethoprim and the ribosome-targeting antibiotic erythromycin in Escherichia coli as a model ...

Carbon Monoxide as an Electron Donor for the Biological Reduction of Sulphate [PDF]

open access: yes, 2010
Several strains of Gram-negative and Gram-positive sulphate-reducing bacteria (SRB) are able to use carbon monoxide (CO) as a carbon source and electron donor for biological sulphate reduction.

Saltwater Intrusion and Submarine Groundwater Discharge: Acceleration of Biogeochemical Reactions in Changing Coastal Aquifers

open access: yesFrontiers in Earth Science, 2021
Intrusion of saltwater into freshwater coastal aquifers poisons an essential resource. Such intrusions are occurring along coastlines worldwide due largely to the over-pumping of freshwater and sea level rise.

Coupled anoxic nitrification/manganese reduction in marine sediments [PDF]

open access: yes, 1999
Pore water and solid phase distributions of oxygen, manganese, and nitrogen from hemipelagic and shelf sediments sometimes indicate a close coupling between the manganese and nitrogen redox cycles.

Sulfate and dissolved sulfide variation under low COD/Sulfate ratio in Up-flow Anaerobic Sludge Blanket (UASB) treating domestic wastewater

open access: yesRevista Ambiente & Água, 2012
In this study, the dynamics of sulfate reduction and dissolved sulfide generation (S2-, HS-, H2Saq) in liquid phase was evaluated in an UASB reactor treating domestic wastewater with low COD/Sulfate content.

Proteomic and Isotopic Response of Desulfovibrio vulgaris to DsrC Perturbation

open access: yesFrontiers in Microbiology, 2019
Dissimilatory sulfate reduction is a microbial energy metabolism that can produce sulfur isotopic fractionations over a large range in magnitude. Calibrating sulfur isotopic fractionation in laboratory experiments allows for better interpretations of ...

Biotechnological aspects of sulfate reduction with methane as electron donor

open access: yes, 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.

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

open access: yesБіологічні 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 ...
