COMPARSION OF GROWTH OF MYCELIUM OF PLEUROTUS CYSTIDIOSUS (MILLER) ON VARIOUS AGAR MEDIA

Abstract

Pleurotus cystidiosus occurs in natural areas on all continents except Antarctica and South America. Fruiting bodies of P. cystidiosus are valued as a source of nutrients and biologically active substances. P. cystidiosus has antitumor, anti-inflammatory and antioxidant, antihyperglycemic activity. This species is cultivated mainly in North America and Asia. The aim of the study was selection the best agar medium for the fastest mycelium growth and the best mycelium hyphal quality. In the experiment, two cultivars of P. cystidiosus from the collection of the Department of Vegetable Crops Poznan University of Life Sciences were used: B1 and B122. Growth of mycelium on five agar media: wheat, potato, synthetic Hansen's, maltose and sawdust was compared. Measure of this parameter was a diameter of agar medium overgrown by hyphae after 7, 10, 14 and 21 days of incubation. Experiment was conducted in Biological Laboratory of the Department of Vegetable Crops Poznan University of Life Sciences. It has been shown that growth of mycelium of tested strains on different agar media was different. Research of mutual dependence between morphological and qualitative characteristics of agar medium type allows production optimization. Development of low-cost, simple method for production of P. cystidiosus can contribute to introduction of this species into intensive cultivation in Poland.
