| Research Abstract |
In a wetland rice field, methane oxidation is active at the oxic-anoxic boundary layer, which plays a crucial role controlling methane emission to the atmosphere. The present study using stable isotope probing approach demonstrated that methanotrophic biomass is immediately grazed by soil protozoa. Soil protozoa including novel amoeba isolated from a rice field soil grazed on methanotrophic bacteria with preferential selection on a certain group. Our results suggested that protozoa is one of the most important biological factors controlling methanotrophic biomass.
