title: [Photochromogeneity of actinomycetes producing heliomycin].
abstract: Irradiation with solar rays of actinomycetes producing heliomycin changed the colour and UV-induced luminescence of the growth medium. This was caused by formation of a luminescent pigment, hydroxyquinone. The aerial mycelium reduced in spore formation acquired a pink colour.
