Methylorubrum extorquens is a Gram-negative bacterium. Methylorubrum species often appear pink, and are classified as pink-pigmented facultative methylotrophs, or PPFMs.[4] The wild type has been known to use both methane and multiple carbon compounds as energy sources.[4] Specifically, M. extorquens has been observed to use primarily methanol and C1 compounds as substrates in their energy cycles.[5] It has been also observed that use lanthanides as a cofactor to increase its methanol dehydrogenase activity[6][7]
