Characteristics of Methanol Production Derived from Methane Oxidation by Inhibiting Methanol Dehydrogenase

Microbial oxidation of methane and methanol: crystallization of methanol dehydrogenase and properties of holo- and apomethanol dehydrogenase from Methylomonas methanica.

Procedures are described for the purification and crystallization of methanol dehydrogenase from the soluble fraction of the type I obligate methylotroph Methylomonas methanica strain S1. The crystallized enzyme is homogeneous as judged by acrylamide gel electrophoresis and ultracentrifugation. The enzyme had a high pH optimum (9.5) and required ammonium salt as an activator. In the presence of...

Methane oxidation by aqueous osmium tetroxide and sodium periodate: inhibition of methanol oxidation by methane.

In silico studies of the mechanism of methanol oxidation by quinoprotein methanol dehydrogenase.

The mechanism of bacterial methanol dehydrogenase involves hydride equivalent transfer from substrate to the ortho-quinone PQQ to provide a C5-reduced intermediate that subsequently rearranges to the hydroquinone PQQH(2). We have studied the PQQ reduction by molecular dynamic (MD) simulations in aqueous solution. Among the five simulated structures, either Asp297 or Glu171 or both are ionized. ...

Methanol promotes atmospheric methane oxidation by methanotrophic cultures and soils.

Two methanotrophic bacteria, Methylobacter albus BG8 and Methylosinus trichosporium OB3b, oxidized atmospheric methane during batch growth on methanol. Methane consumption was rapidly and substantially diminished (95% over 9 days) when washed cell suspensions were incubated without methanol in the presence of atmospheric methane (1.7 ppm). Methanotrophic activity was stimulated after methanol (...
