Dynamics of the methanogenic archaeal community during plant residue decomposition in an anoxic rice field soil.

ABSTRACT: Incorporation of plant residues strongly enhances the methane production and emission from flooded rice fields. Temperature and residue type are important factors that regulate residue decomposition and CH(4) production. However, the response of the methanogenic archaeal community to these factors in rice field soil is not well understood. In the present experiment, the structure of the archaeal community was determined during the decomposition of rice root and straw residues in anoxic rice field soil incubated at three temperatures (15 degrees C, 30 degrees C, and 45 degrees C). More CH(4) was produced in the straw treatment than root treatment. Increasing the temperature from 15 degrees C to 45 degrees C enhanced CH(4) production.
