Abstract
Gram-negative, methylotrophic bacteria convert methanol into formaldehyde via NAD(P)-independent methanol dehydrogenase (MDH) with pyrroloquinoline quinone (PQQ) as the cofactor. The activity of MDH can be measured in vitro at pH 9 in the presence of ammonium salts as activator and with artificial dyes as electron acceptor (Anthony, 1982). In the Gram-positive bacterium Nocardia sp. 239 such an enzyme is absent, although it excretes substantial amounts of PQQ into the medium during growth on methanol (Hazeu et al., 1983).
