Diversity of Methanotrophic Bacteria Community between Different Development Stages in Chinese Temperate Forest

Abstract:

The method of terminal restriction fragment length polymorphism (T-RFLP) was used to study the community structures and diversities of aerobic methanotrophs by the key functional genes pmoA in the forest land soils of Changbai Mountains in China. And the effects of soil factors on them were also evaluated, and then the mechanism of microbiological communities in forest land soils response to the forest succession were discussed. The results showed that the diversity indices of aerobic methanotrophs were higher, and community structures appeared more complicated at the later plots. Their similarity coefficients gradually declined from the middle of the forest succession to the adjacent forest, indicating communities dynamic succession. During succession process, soil moisture and organic matter content had significant influence on it. The microbial communities were under the stress of succession process, which led to more emission of other greenhouse-gas from forest soils.
