Interactions between Cyanobacteria and Methane Processing Microbes Mitigate Methane Emissions from Rice Soils.

ABSTRACT: Cyanobacteria play a relevant role in rice soils due to their contribution to soil fertility through nitrogen (N₂) fixation and as a promising strategy to mitigate methane (CH₄) emissions from these systems. However, information is still limited regarding the mechanisms of cyanobacterial modulation of CH₄ cycling in rice soils. Here, we focused on the response of methane cycling microbial communities to inoculation with cyanobacteria in rice soils. We performed a microcosm study comprising rice soil inoculated with either of two cyanobacterial isolates (Calothrix sp. and Nostoc sp.) obtained from a rice paddy. Our results demonstrate that cyanobacterial inoculation reduced CH₄ emissions by 20 times. Yet, the effect on CH₄
