Microbial hauberks: composition and function of surface layer proteins in gammaproteobacterial methanotrophs

Applied and Environmental Microbiology
Many species of proteobacterial methane-consuming bacteria (methanotrophs) form a hauberk-like envelope represented by a surface (S-) layer protein (SLP) matrix.

Origin of Sedimentary BHPs Along a Mississippi River–Gulf of Mexico Export Transect: Insights From Spatial and Density Distributions

Frontiers in Marine Science, 2019
We investigated the origin of sedimentary bacteriohopanepolyols (BHPs) in low-density (<1.6 g cm–3), mesodensity (1.6–2.0 and 2.0–2.5 g cm–3) and high-density fractions (>2.5 g cm–3) as well as unfractionated bulk samples in a highly dynamic ...

State-of the-Art Constraint-Based Modeling of Microbial Metabolism: From Basics to Context-Specific Models with a Focus on Methanotrophs

Microorganisms, 2023
Methanotrophy is the ability of an organism to capture and utilize the greenhouse gas, methane, as a source of energy-rich carbon. Over the years, significant progress has been made in understanding of mechanisms for methane utilization, mostly in ...

Hydrologic History Regulates Microbial Biofilm Diversity and Ecosystem Function

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Hydrologic history regulates microbial biofilm diversity and ecosystem function. Historical flooding, but not drought, led to broad changes in composition and functional genes. ABSTRACT Aquatic biofilms are an understudied component of northern peatlands and are expected to play a more prominent role in ecosystem processes in areas where aquatic ...

Methane‐limited methanotrophy in tidal freshwater swamps [PDF]

Global Biogeochemical Cycles, 2002
We investigated the relationship between CH4 production and oxidation in two tidal freshwater wetland forests in order to determine whether CH4 oxidation efficiency was limited by O2 or CH4. Methane oxidation was measured in situ over a 16‐month period with bi‐monthly applications of the inhibitor CH3F.

Evaluating the contribution of methanotrophy kinetics to uncertainty in the soil methane sink

Environmental Research Letters
The oxidation of atmospheric methane by soil microbes is an important natural sink for a potent greenhouse gas. However, estimates of the current and future soil methane sink are highly uncertain. Here we assessed the extent to which methanotrophy enzyme

Holocene variations in peatland methane cycling associated with the Asian summer monsoon system [PDF]

, 2014
Atmospheric methane concentrations decreased during the early to middle Holocene; however, the governing mechanisms remain controversial. Although it has been suggested that the mid-Holocene minimum methane emissions are associated with hydrological ...

Keeping Pace With Intensifying Agricultural Field Inundation Events: A Framework for Testing the Mitigative Capacity of Current Best Management Practices

Global Change Biology, Volume 32, Issue 4, April 2026.
ABSTRACT According to data from the USDA's Risk Management Agency, crop insurance indemnities related to precipitation, hurricanes, excess moisture, and field inundation have totaled approximately $3.65 billion across Illinois, Indiana, and Iowa over the past decade.

Projected Methane Emissions From a Boreal Thermokarst Bog Are Sensitive to Carbon Substrate Availability, Distribution, and Transport Pathway Dominance

Global Change Biology, Volume 32, Issue 4, April 2026.
Projected radiative forcing from a thermokarst bog in Boreal Alaska depends on methane emission transport pathway dominance, with aerenchyma‐ and diffusion‐dominant causing net warming and ebullition‐dominant causing net cooling. Predicted methane shows a transient response as air temperature increases in future projections causing soil drying and ...
