Effect of application of rice straw and cellulose on methane emission and biological nitrogen fixation in a subtropical paddy field: Iii. populations of methane-oxidizing bacteria in soil and rice rhizosphere

Abstract

Methane-oxidizing bacteria (MOB, methanotrophs) limit the flux of methane to the atmosphere from sediments and soils, and consume atmospheric methane (King 1992; Oremland and Culbertson 1992). IPCC (1995) reported that an aerobic soil is equivalent to a sink of 10–20% of methane emissions. Hence MOB play an important role in regulating the atmospheric methane content (Mancinelli 1995). Over the last 20y, although a large amount of information has been supplied on the biochemistry of MOB, few ecological investigations have been devoted to them so far (Holzapfel-Pschorn et al. 1985; Oremland and Culbertson 1992). © 1997 Taylor & Francis Group, LLC.
