Ecological study of methane-oxidizing bacteria in low-oxygen environments was performed. In water of a subtropical reservoir, one of the dominant microbes was close relative of a methane-oxidizing bacterium which has ability to oxidize methane under anoxic conditions. Possible interaction between methane-oxidizing and iron-reducing bacteria was suggested by microscopic observation of snow sample which contained both of those organisms.

对低氧环境下的甲烷氧化菌进行了生态学研究。在亚热带水库的水中，一种优势微生物与甲烷氧化细菌是近亲，能够在缺氧条件下氧化甲烷。通过对含有甲烷氧化细菌和铁还原细菌的雪样进行显微镜观察，发现这两种细菌之间可能存在相互作用。
