13C Nuclear Magnetic Resonance Spectra of Fungal Melanins

Abstract

The 13C resonance spectra of fungal melanins from A spergillus 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. © 1978, Walter de Gruyter. All rights reserved.
