title: [Melanin pigments of the fungi Paecilomyces variotii and Aspergillus carbonarius].
abstract: Pigments synthesized by micromycetes Paecilomyces variotii and Aspergillus carbonarius are true melanins. Copper ions and bicyclic phenolic compounds stimulated melaninogenesis, whereas benzotriazole inhibited this process. Precursors of melanin pigments were obtained and identified. p-Hydroxybenzoic acid was shown to be the main product of melanin degradation. Melanins of these fungi are concluded to belong to the dihydronaphthalene group.
