Methylocella silvestris is an acidophilic, Gram-negative, non-pigmented, non-motile, rod-shaped, aerobic methane-oxidizing bacteria isolated from an acidic forest cambisol (soil characterized by an absence of a layer of accumulated clay, humus, soluble salts, or iron and aluminum oxides) near Marburg, Germany. Unlike other methanotrophs, Methylocella is a catabolically flexible "facultative methanotroph", able to grow on some multicarbon substrates such as acetate, ethanol, pyruvate, succinate, malate and propane. It is able to fix atmospheric nitrogen via an oxygen-sensitive nitrogenase. The cells possess a highly specific bipolar appearance. They lack the intracytoplasmic membranes common to all methane-oxidizing bacteria except Methylocella, but contain a vesicular membrane system connected to the cytoplasmic membrane. A soluble methane monooxygenase was present, but no particulate methane monooxygenase could be detected. These bacteria utilize the serine pathway for carbon assimilation. It is capable of growth at pH values between 4.5 and 7 (with an optimum at pH 5.5) and at temperatures between 4 and 30 degrees C. Compared with Methylocella palustris KT, these strains have greater tolerance of cold temperatures, dissolved salts and methanol. This is the type strain (adapted from and PubMed 13130000).
