Decreased susceptibility of melanized Cryptococcus neoformans to UV light

Appl Environ Microbiol. 1994 Oct;60(10):3864-6. doi: 10.1128/aem.60.10.3864-3866.1994.

Abstract

Melanized Cryptococcus neoformans cells were less susceptible than nonmelanized cells to the fungicidal effects of UV light. Phenoloxidase-catalyzed production of melanin-like pigments may serve to protect the fungus against ionizing radiation.
