Effects of nickel and cobalt on methane production and methanogen abundance and diversity in paddy soil.

ABSTRACT:

Background

Paddies are an important anthropogenic source of methane emissions to the atmosphere, and they are impacted by heavy metal pollution. Nickel (Ni) and cobalt (Co) pollution might either enhance or mitigate CH₄ emission from paddy soils due to the total amounts of metals, bioavailability and functional microbial activity and composition.

Methods

An incubation experiment was conducted, and different Ni and Co concentrations were added to test the effects of trace metals on methane production in paddy soil. The archaea community structure and the abundance of methanogen functional groups in the paddy soil with added Ni and Co were detected using high-throughput sequencing and quantitative PCR based on the 16S rRNA and mcrA (methyl coenzyme M reductase) gene
