A common strategy for many microorganisms mediating biogeochemical cycles in anoxic environments is syntrophy, frequently necessitating close spatial proximity between microbial partners.
In seep sediments, N2 fixation was dependent on CH4 and coincident with sulfate reduction, consistent with previous work showing diazotrophy by microorganisms mediating sulfate-coupled methane oxidation.
We examined the response of ammonia-oxidizing bacteria (AOB), microorganisms that mediate the transformation of ammonium into nitrite, to simultaneous increases in atmospheric CO2, precipitation, temperature, and nitrogen deposition, manipulated on the ecosystem level in a California grassland.
Immune responses against intracellular microorganisms are mediated by T helper type 1 (Th1) cells, which produce interferon (IFN -γ as theIFN -γlmask cytheire [ 1].
The discovery, that dense cell wall containing microorganisms can undertake mediated EET, adds to the body of knowledge towards building a comprehensive understanding of biogeochemical and bioelectrical processes.
Microbial Enzymes and Biotransformation provides practical experimental laboratory procedures for a wide range of enzymes and biotransformations mediated by microorganisms.
These transfers could yield insights into the nature of modern-day genetic exchange mediated by microorganisms associated with the human body.
Biochemical weathering, often concurring with its mechanical counterpart, is mediated by microorganisms through mechanisms that include: the release of compounds that promote weathering, such as organic acids, chelators, and reactive species (e.g., H+).
