Biotechnological aspects of sulfate reduction with methane as electron donor [PDF]

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.

Cooccurrence of Aerobic and Anaerobic Methane Oxidation in the Water Column of Lake Plußsee [PDF]

open access: yesApplied and Environmental Microbiology, 2005
ABSTRACT Dissolved methane was investigated in the water column of eutrophic Lake Plußsee and compared to temperature, oxygen, and sulfide profiles. Methane concentrations and δ- 13 C signatures indicated a zone of aerobic methane oxidation and additionally a zone of anaerobic methane oxidation in the ...

Microbial catabolic activities are naturally selected by metabolic energy harvest rate [PDF]

open access: yes, 2015
The fundamental trade-off between yield and rate of energy harvest per unit of substrate has been largely discussed as a main characteristic for microbial established cooperation or competition.

In Vivo Evidence of Single 13C and 15N Isotope–Labeled Methanotrophic Nitrogen-Fixing Bacterial Cells in Rice Roots

open access: yesmBio, 2022
Methane-oxidizing bacteria (methanotrophs) play an ecological role in methane and nitrogen fluxes because they are capable of nitrogen fixation and methane oxidation, as indicated by genomic and cultivation-dependent studies.

Novel Methanotrophs of the Family Methylococcaceae from Different Geographical Regions and Habitats [PDF]

open access: yes, 2015
Terrestrial methane seeps and rice paddy fields are important ecosystems in the methane cycle. Methanotrophic bacteria in these ecosystems play a key role in reducing methane emission into the atmosphere.

Insights into the Ecological Roles and Evolution of Methyl-Coenzyme M Reductase-Containing Hot Spring Archaea [PDF]

open access: yes, 2019
Several recent studies have shown the presence of genes for the key enzyme associated with archaeal methane/alkane metabolism, methyl-coenzyme M reductase (Mcr), in metagenome-assembled genomes (MAGs) divergent to existing archaeal lineages.

Aerobic methanotrophy within the pelagic redox-zone of the Gotland Deep (central Baltic Sea) [PDF]

open access: yesBiogeosciences, 2012
Water column samples taken in summer 2008 from the stratified Gotland Deep (central Baltic Sea) showed a strong gradient in dissolved methane concentrations from high values in the saline deep water (max.

Aerobic methanotrophic communities at the Red Sea brine-seawater interface

open access: yesFrontiers in Microbiology, 2014
The central rift of the Red Sea contains 25 brine pools with different physicochemical conditions, dictating the diversity and abundance of the microbial community.

Advance in Numerical Simulation Research of Marine Methane Processes

open access: yesFrontiers in Earth Science, 2022
Understanding the modern marine methane processes, which can profoundly affect global climate and have far-reaching impacts on human living environments, is critical for research on the global carbon cycle.

Methane emission from hypersaline microbial mats: Lack of aerobic methane oxidation activity [PDF]

open access: yesFEMS Microbiology Ecology, 1995
Methane emission was measured in intact cores of microbial mats taken from hypersaline Solar Lake (Sinai) and from salterns of the city of Eilat at salinities of 9% and 13%, respectively. The CH4 emission rates were 0.4–2.2 nmol cm−2 h−1 irrespectively of the incubation conditions, i.e.
