Magenta pigment produced by fungus

抄録

A fungus producing magenta was isolated from cellulosic material by visual observation on Czapek's agar media and the product was conventionally analyzed. The fungal strain that produced magenta pigment was closely related to Phoma herbarum. The type of fibers added to Czapek's medium influenced which pigments were produced. Mycelia attached to the surface of nylon-6 and excreted magenta pigment into the fibers. The pigment structure was partially determined. This is the first report of the production of magenta pigment by a microorganism specifically in the presence of nylon-6 fibers, via an unknown mechanism. This phenomenon raises the question of why and how the fungus disperses the pigment inside the fiber and suggests that fabrics can be dyed using microorganisms.
