A new water-soluble photochromogenic fluorescent violet pigment with the indicator properties was isolated from the culture fluid of Nocardia fructiferi var. ristomycini, strain 76. By its solubility and mobility in various solvent systems and by the absorption spectrum the new pigment is close but not identical to such a pigment as rubrocyanin. The presence of microelements, i.e. iron and magnesium in the medium was shown to be necessary for production of violet pigment.
