Effect of metal cations on the formation of antibiotic and pigment by the mycophilic fungus Hypomyces rosellus 94/77

Using the method of mathematical planning of experiment the effect of calcium, magnesium, manganese, iron, zinc and copper on synthesis of antibiotic and pigment by mycophilic fungus Hypomyces rosellus has been studied. The ions of Mg2+, Mn2+, Fe2+ have been found to be important for antibiotic and pigment formation by fungus, the ions of Mg2+ and Mn2+ are interchangeable.
