Detection of Bacteria in Environmental Samples by Direct PCR Without DNA Extraction

BioTechniques, 2001
Cultured cells and environmental samples were used directly in PCRs without the isolation of DNA. Serial dilution was used to eliminate the inhibitory effect of materials in natural samples.

Soil Methanogen and Methanotroph Communities of Four Land Use Types in Dongting Lake Area: Linkages with Potential Methane Production

Agronomy
Methane (CH4) emissions are regulated by the balance between CH4 production and oxidation, which are mediated by methanogens and methanotrophs. Little is known about the key drivers of potential methane production (PMP) under different land use types in ...

Controlling Methane Ebullition Flux in Cascade Reservoirs of the Upper Yellow River by the Ratio of mcrA to pmoA Genes

Water
Reservoirs are an important source of methane (CH4) emissions, but the relative contribution of CH4 ebullition and diffusion fluxes to total fluxes has received little attention in the past. In this study, we systematically monitored the CH4 fluxes of nine cascade reservoirs (Dahejia, Jishixia, Huangfeng, Suzhi, Kangyang, Zhiganglaka, Lijiaxia, Nina ...

Raised Seedbed Cultivation with Annual Rice–Spring Crop Utilization Enhances Crop Yields and Reshapes Methane Functional Microbiome Assembly and Interaction Networks

Agronomy
Tillage and crop rotation alter soil environments, thereby influencing both crop yields and methane-cycling microbiomes, yet their combined effects on microbial diversity, assembly, and interaction networks remain unclear.

Copper’s dual role in aerobic methane oxidation coupled with aerobic denitrification: Boosts CH4-derived carbon for denitrification but inhibits it via methanobactin competition

Water Research X
Aerobic methane oxidation coupled with aerobic denitrification (AME-AD) has the capability to remove nitrate and reduce methane (CH4) under aerobic conditions.

The methane-oxidizing microbial communities of three maar lakes in tropical monsoon Asia

Frontiers in Microbiology
Methane-oxidizing bacteria (MOB) is a group of planktonic microorganisms that use methane as their primary source of cellular energy. For tropical lakes in monsoon Asia, there is currently a knowledge gap on MOB community diversity and the factors ...

Interactive Effect of Soil Properties and Microbial Functional Genes on Methane and Nitrous Oxide Emissions in Rice Paddies: A Global Meta-Analysis

Yüzüncü Yıl Üniversitesi Tarim Bilimleri Dergisi
Rice paddies are a major anthropogenic source of methane (CH₄) and nitrous oxide (N₂O), yet the interactive roles of soil properties and microbial functional groups in regulating both gases remain poorly quantified. While individual studies have examined
