Influences of nitrogen sources on usnic acid production in a cultured Mycobiont of the lichen Usnea hirta (L.) Wigg.
Effects of the nitrogen sources in the medium for the production of secondary metabolites in lichens were examined. The usnic acid production by a mycobiont of the lichen Usnea hirta was higher in the liquid medium containing ammonium and nitrate ions than in those containing amino acids.
