13C nuclear magnetic resonance spectra of fungal melanins. 1978

F J Gonzalez-Vila, and C Saiz-Jimenez, and H Lentz, and H D Lüdemann

The 13C resonance spectra of fungal melanins from Aspergillus niger, Eurotium echinolatum, and Stachybotrys chartarum are reported. The spectra were taken in 5% W/W solution of the substances in 0.1 N NaOD in D2O using the Fourier-transform-technique. The spectra and possible assignments of the bands are discussed. The similarities of these spectra to those of soil humic acids are unexpectedly small.

UI MeSH Term Description Entries
D008543 Melanins Insoluble polymers of TYROSINE derivatives found in and causing darkness in skin (SKIN PIGMENTATION), hair, and feathers providing protection against SUNBURN induced by SUNLIGHT. CAROTENES contribute yellow and red coloration. Allomelanins,Melanin,Phaeomelanins
D009682 Magnetic Resonance Spectroscopy Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons.

D005658 Fungi A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies. Fungi, Filamentous,Molds,Filamentous Fungi,Filamentous Fungus,Fungus,Fungus, Filamentous,Mold
D001234 Aspergillus niger An imperfect fungus causing smut or black mold of several fruits and vegetables such as grapes, apricots, onions, and peanuts, and is a common contaminant of food. Aspergillus lacticoffeatus
