Hyphal walls of Aspergillus phoenicis and Sclerotium rolfsii are composed of large amounts of glucose- and N-acetylhexosamine-containing polysaccharides, and the walls are extensively digested by streptomycete culture filtrates or by a mixture of purified chitinase and beta-(1 --> 3) glucanase preparations with the release of the monomeric units. A. phoenicis conidial walls also contain polymer...

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 ...

Melanins play a fundamental role in the biology and ecology of several fungal species. Unfortunately, this group amorphous macromolecules also severely (and most times irreversibly) stains cultural heritage objects. Despite efforts made throughout years, knowledge chemical composition structure melanins is still insufficient, which hampers task safely cleaning these colourants from materials ta...
