Reducing equivalents from each oxidation step could be utilized, in vivo, to stimulate methane mono-oxygenase activity. As neither oxidation step produces NADH directly, these observations are presented as evidence for reverse electron transport in methanotrophs. In type II methanotrophs, 5 mm-acetate, propionate and butyrate also stimulate methane mono-oxygenase activity apparently by inducing the breakdown of poly-β-hydroxybutyrate. subsequent metabolism of β-hydroxybutyrate giving rise to NADH. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-129-11-3487
