13C nuclear magnetic resonance spectra of fungal melanins

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