Methylocella silvestris

Methylocella silvestris is a bacterium from the genus Methylocella spp which are found in many acidic soils and wetlands.^[1] Historically, Methylocella silvestris was originally isolated from acidic forest soils in Germany, and it is described as Gram-negative, aerobic, non-pigmented, non-motile, rod-shaped and methane-oxidizing facultative methanotroph.^[2] As an aerobic methanotrophic bacteria, Methylocella spp use methane (CH₄), and methanol as their main carbon and energy source, as well as multi compounds acetate, pyruvate, succinate, malate, and ethanol.^[3] They were known to survive in the cold temperature from 4° to 30° degree of Celsius with the optimum at around 15° to 25 °C, but no more than 36 °C. They grow better in the pH scale between 4.5 to 7.0.^[1] It lacks intracytoplasmic membranes common to all methane-oxidizing bacteria except Methylocella, but contain a vesicular membrane system connected to the cytoplasmic membrane. BL2^T (=DSM 15510^T=NCIMB 13906^T) is the type strain.
