  • Title: (1-14C) acetate assimilation by obligate methylotrophs, Pseudomonas methanica and Methylosinus trichosporium.
    Author: Patel RN, Hoare SL, Hoare DS.
    Journal: Antonie Van Leeuwenhoek; 1979; 45(3):499-511. PubMed ID: 122051.
    Abstract:
    The oxidation of one carbon compounds (methane, methanol, formaldehyde, formate) and primary alcohols (ethanol, propanol, butanol) supported the assimilation of [1-14C]acetate by cell suspensions of type I obligate methylotroph, Pseudomonas methanica, Texas strain, and type II obligate methylotroph, Methylosinus trichosporium, strain PG. The amount of oxygen consumed and substrate oxidized correlated with the amount of [1-14C]acetate assimilated during oxidation of C-1 compounds and primary alcohols. Oxidation of methanol, formaldehyde, and primary alcohols in extracts of Pseudomonas methanica, Texas strain, and Methylosinus trichosporium, strain PG, was catalyzed by a phenazine methosulfate linked, ammonium ion dependent methanol dehydrogenase. The oxidation of aldehydes was catalyzed by a phenazine methosulfate linked, ammonium ion independent aldehyde dehydrogenase. Formate was oxidized by a NAD+ linked formate dehydrogenase.
