Total flavonoid content, lipid peroxidation and total antioxidant activity of Hericium coralloides, Fomes fomentarius and Schizophyllum commune cultivated by the method of direct confrontation
The patterns of culture growth, fruiting, total flavonoid content, lipid peroxidation and antioxidant properties were established for Hericium coralloides, Fomes fomentarius and Schizophyllum commune, and cultivated on Potato Glucose Agar by the method of direct confrontation. Co-cultivation is accompanied by the inhibition of the colonies’ growth. The highest inhibitory effect was found to H. coralloides, and minimal inhibitory values were established to S. commune. In the fruiting bodies of H. coralloides, F. fomentarius and S. commune that were formed on a different co-culture composition (except H. coralloides + F. fomentarius composition), an increase of total flavonoid content and total antioxidant activity were observed. Direct confrontation conditions are a stress for cultures because an increase of lipid peroxidation level in the fruiting bodies was observed. Tendency of accumulation of total flavonoid content in the H. coralloides, F. fomentarius and S. commune fruiting bodies is an important antifungal aspect in co-cultivation of macromycetes, because the accumulation of flavonoids directly correlates to the magnitude of inhibition of the H. coralloides and F. fomentarius culture growth. This means that fungi have clear mechanisms of counteraction to competitors. However, practical application of this phenomenon is questionable.
