Characteristics and metabolic patterns of soil methanogenic archaea communities in the high‐latitude natural forested wetlands of China

open access: yesEcology and Evolution, 2021
Soil methanogenic microorganisms are one of the primary methane‐producing microbes in wetlands. However, we still poorly understand the community characteristic and metabolic patterns of these microorganisms according to vegetation type and seasonal ...

Baltic Sea methanogens compete with acetogens for electrons from metallic iron

open access: yesThe ISME Journal, 2019
Microbially induced corrosion of metallic iron (Fe0)-containing structures is an environmental and economic hazard. Methanogens are abundant in low-sulfide environments and yet their specific role in Fe0 corrosion is poorly understood.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Uncovering the Diversity and Activity of Methylotrophic Methanogens in Freshwater Wetland Soils

open access: yesmSystems, 2019
Understanding the sources and controls on microbial methane production from wetland soils is critical to global methane emission predictions, particularly in light of changing climatic conditions.

Seasonal and Regional Dietary Heterogeneity Is Associated With Gut Microbiota Differentiation in Przewalski's Gazelle (Procapra przewalskii)

open access: yesIntegrative Zoology, EarlyView.
Seasonal and regional dietary variation in Przewalski's gazelle was linked to coordinated changes in gut microbiota, functional pathways, and fecal metabolites. Winter diets featured Poaceae, Cyperaceae, and Iridaceae, whereas summer diets shifted toward forb families.

Research progress on relationship between rumen anaerobic fungi and methanogens and their application

open access: yesSiliao yanjiu, 2021
Rumen of ruminants, as a natural fermentation system, is inhabited by a large number of microorganisms, which has formed a dynamic equilibrium relationship in long-term evolution.

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen

open access: yesThe FEBS Journal, EarlyView.
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Sources and dynamics of methanogens in Humans

open access: yes, 2022
Les méthanogènes sont présents dans le microbiote humain dès la naissance avec une diversification au fil des années. Cependant, le répertoire complet, les sources et la dynamique des méthanogènes restent méconnus chez l’Homme d’où mon projet de thèse ...

Diversity of methanogens in ruminants in Queensland [PDF]

open access: yes, 2008
Methane emissions from ruminant livestock represent a loss of carbon during feed conversion, which has implications for both animal productivity and the environment because this gas is considered to be one of the more potent forms of greenhouses gases ...

Delivering Sulfate to LNAPL Body for Enhanced Source Zone Depletion (ESZD)

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract This field pilot study evaluates the feasibility of applying sulfate to a light non‐aqueous phase liquid (LNAPL) body for achieving enhanced source zone depletion (ESZD) at a refinery site. Two rounds of gypsum land application (GLA) delivered sulfate to an 8000 ft2 area encompassing LNAPL‐containing monitoring wells MW‐2 and MW‐3, while MW‐1 ...
