Environmental Factors Affecting the Community of Methane-oxidizing Bacteria.

ABSTRACT: Methane-oxidizing bacteria (MOB) are ubiquitous and play an important role in the mitigation of global warming by reducing methane. MOB are commonly classified into Type I and Type II, belonging to Gammaproteobacteria and Alphaproteobacteria, respectively, and the diversity of MOB has been examined. However, limited information is currently available on favorable environments for the respective MOB. To investigate the environmental factors affecting the dominant type in the MOB community, we performed MOB enrichment using down-flow hanging sponge reactors under 38 different environmental conditions with a wide range of methane (0.01-80%) and ammonium concentrations (0.001-2,000‍ ‍mg N L^-1) and pH 4-7. Enrichment results revealed that pH was a crucial factor influencing the MOB t
