The diversification and potential function of microbiome in sediment-water interface of methane seeps in South China Sea

open access: yesFrontiers in Microbiology
The sediment-water interfaces of cold seeps play important roles in nutrient transportation between seafloor and deep-water column. Microorganisms are the key actors of biogeochemical processes in this interface.

Monodeuterated Methane, an Isotopic Tool To Assess Biological Methane Metabolism Rates

open access: yesmSphere, 2017
Biological methane oxidation is a globally relevant process that mediates the flux of an important greenhouse gas through both aerobic and anaerobic metabolic pathways.

Identification of Novel Methane-, Ethane-, and Propane-Oxidizing Bacteria at Marine Hydrocarbon Seeps by Stable Isotope Probing [PDF]

open access: yes, 2010
Marine hydrocarbon seeps supply oil and gas to microorganisms in sediments and overlying water. We used stable isotope probing (SIP) to identify aerobic bacteria oxidizing gaseous hydrocarbons in surface sediment from the Coal Oil Point seep field ...

Metabolic Network Analysis of Microbial Methane Utilization for Biomass Formation and Upgrading to Bio-Fuels

open access: yesFrontiers in Energy Research, 2018
The potent greenhouse gas methane presents a widely accessible resource, being the primary component in natural gas as well as in bio-gas from anaerobic digesters.

Ecological Aerobic Ammonia and Methane Oxidation Involved Key Metal Compounds, Fe and Cu

open access: yesLife, 2022
Interactions between metals and microbes are critical in geomicrobiology and vital in microbial ecophysiological processes. Methane-oxidizing bacteria (MOB) and ammonia-oxidizing microorganisms (AOM) are key members in aerobic environments to start the C

Stratification of aerobic methane‐oxidizing organisms in Lake Mendota, Madison, Wisconsin1 [PDF]

open access: yesLimnology and Oceanography, 1980
The microflora responsible for methane oxidation are stratified in a narrow band in the thermocline of Lake Mendota where dissolved oxygen is low during summer. Oxygen sensitivity of growth of these organisms or of methane oxidation cannot account for their absence from the epilimnion because oxygen does not inhibit either process under in situ ...

ECOSSE: Estimating Carbon in Organic Soils - Sequestration and Emissions: Final Report [PDF]

open access: yes, 2007
Background Climate change, caused by greenhouse gas ( GHG) emissions, is one of the most serious threats facing our planet, and is of concern at both UK and devolved administration levels.

Nitrogen removal in marine environments: recent findings and future research challenges [PDF]

open access: yes, 2005
Respiratory reduction of nitrate (denitrification) is recognized as the most important process converting biologically available (fixed) nitrogen to N2. In current N cycle models, a major proportion of global marine denitrification (50–70%) is assumed to

Study on Oxidation Rate and Isotope Fractionation of Methane in Bohai Sea Sediments

open access: yesYankuang ceshi, 2018
BACKGROUND:The Bohai Sea contains a large amount of oil and gas, the main component of which is methane. The influence of natural or human factors will cause its leakage and migration and then have a negative impact on the environment.
