title: Influences of nitrogen sources on usnic acid production in a cultured Mycobiont of the lichen Usnea hirta (L.) Wigg.
abstract: 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.
