Effect of Copper on Methylomonas albus BG8.
Addition of copper to the medium for Methylomonas albus BG8 increased cell yield and methane monooxygenase activity. Intracytoplasmic membrane was formed only in cells grown with copper supplementation. Additionally, the abundances of two major membrane proteins were affected by copper in the growth medium. These findings indicate that effects of copper on the physiology of methanotrophic bacteria are not limited to those on types II and X.
