Abstract: | The mycelium of Streptomyces chryzomallus var. macrotetrolidi producing the macrotetrolide antibiotic nonactin was shown to be capable of carbon dioxide fixation. Carbon was found to be incorporated into nonactin and macromolecular compounds in the biomass. Carbon was incorporated within 20 to 40 min of the mycelium incubation with NaH14CO3. Pyruvic and propionic acids stimulated carbon incorporation. |
