Characterization and Biotechnology of Three New Strains of Basidial Fungi as Promising Sources of Biologically Active Substances

Summary

This research focused on studying three new strains of medicinal mushrooms to determine the best ways to grow them in laboratory conditions. The findings show these fungi can be efficiently cultivated to produce beneficial compounds for use in medicines, supplements, and cosmetics. Impacts on everyday life: • Could lead to new natural supplements and medicines derived from these mushrooms • May provide more sustainable sources of beneficial compounds for cosmetic products • Helps advance our understanding of how to efficiently grow medicinal mushrooms • Could make mushroom-based health products more accessible and affordable • Demonstrates potential for developing new natural alternatives to synthetic compounds

Background

Basidiomycetes cultivation in artificial conditions to study their synthesized substances is an urgent task, as their fruiting bodies contain biologically active components promising for supplements and medicines. While some species like Ganoderma lucidum and Lentinus edodes are well-known, expanding the spectrum of higher fungi that efficiently produce active components remains of practical interest.

Objective

The aim was to isolate new cultures of the fungi Daedaleopsis tricolor, Pycnoporellus fulgens and Trichaptum abietinum from natural fruiting bodies and improve their growth conditions on solid nutrient media. The study sought to identify optimal cultivation conditions for intensive growth and biomass accumulation.

Results

The optimal cultivation temperature was 27°C for all studied strains. The highest radial growth was observed on synthetic medium for D. tricolor (5.26 mm/day) and T. abietinum (7.5 mm/day), and on synthetic medium with lignin for P. fulgens (2.98 mm/day). The biomass amount of D. tricolor KS11 was 133.25 mg at 9 days, P. fulgens KS12 was 86.73 mg at 16 days, and T. abietinum KS10 was 227.33 mg at 6 days.

Conclusion

New strains of D. tricolor KS11, P. fulgens KS12 and T. abietinum KS10 were successfully isolated and characterized. T. abietinum KS10 proved to be the most productive strain with fastest growth and highest biomass accumulation. These new fungal strains show promise for obtaining biologically active substances for food, pharmaceutical and cosmetic industries.
