Melanin, melanin "ghosts," and melanin composition in Cryptococcus neoformans [PDF]
Infection and Immunity, 1996 Melanin synthesis is associated with virulence for the pathogenic fungus Cryptococcus neoformans. Exposure of nonmelanized C. neoformans 4067 cells to 4 M guanidinium isothiocyanate followed by 6 M HCl at 100 degrees C resulted in complete solubilization of cellular structures. However, exposure of melanized C.
