Anthraquinone pigments production by brown mutant Trichoderma viride M-108 under various nutrition conditions

In this work the influence of 12 carbon and 9 nitrogen sources on pigment production of brown mutant Trichoderma viride M-108 was tested. There were two concentrations of nutrient sources used and the tests were carried out in three light regimes. The pigmentation was good only on media containing sodium nitrate, sodium nitrite, sucrose, starch and glycerol and there was no pigment production on media with adenine, ammonium chloride and ammonium sulphate. In mixtures of pigments, individual compounds were determined by using thin-layer chromatography and UV spectra of colour fractions.
