Compare and contrast methanogens and methane oxidizers, including their roles in the environment
What will be an ideal response?
Methanogens are archaea (in the phylum Euryarchaeota), and methane oxidizers are bacteria of the phylum Proteobacteria, so they are fundamentally different in all the ways these two domains differ. The methanogens produce methane gas from organic materials, and the bacterial methane oxidizers metabolize methane gas to produce organic compounds and cellular energy. Both types of prokaryotes live in anaerobic environments and often grow in proximity to each other. Thus, their metabolic activities with respect to methane are complementary and contribute to recycling of biomolecules.
