Biochemical pathway of melanin production
WebSep 9, 2024 · Melanin is a natural pigment that is produced by filamentous fungi. In this study, the endophytic species, Spissiomyces endophytica (strain SDBR-CMU319), produced a brown-black pigment in the mycelia. Consequently, the pigment was extracted from the dried fungal biomass. This was followed by pigment purification, characterization and … WebMelanin refers to a family of biologic molecules that cause pigmentation of different structures and tissues. Melanin pigment consists of aggregates of monomers that form a …
