Contribution to Studies on Rare Medicinal Mushroom Sparassis crispa (Agaricomycetes) in Culture and Its Production of Phenol Compounds Under Various Cultivation Conditions

Summary

This research focused on studying how to grow the medicinal mushroom Sparassis crispa and optimize its production of beneficial compounds in laboratory conditions. The researchers discovered specific growing conditions that help the mushroom produce more valuable chemicals, particularly a compound called sparassol. Impacts on everyday life: • Improved cultivation methods could make this medicinal mushroom more accessible for medical use • Better understanding of growing conditions helps optimize production of beneficial compounds • Identification of specific strains that produce more active compounds can lead to more effective medicinal products • This research contributes to making natural medicine production more efficient and cost-effective

Background

Sparassis crispa is a rare medicinal mushroom that produces various phenol compounds. Understanding its growth patterns and compound production under different cultivation conditions is important for optimizing its medicinal potential.

Objective

To study three Sparassis crispa strains from the Komarov Botanical Institute Basidiomycetes Culture Collection (LE-BIN) on various agar and liquid media to evaluate their growth patterns and phenol compound production under different conditions.

Results

The strains produced visible crystals that were identified as sparassol (methyl 2-hydroxy-4-methoxy-6-methylbenzoate). Additional phenol compounds including methyl ester of sparassol and methyl ester of orsellinic acid were found in the mycelium. While initial pH had minimal impact, cultivation duration directly correlated with sparassol concentration. Strain LE-BIN 2902 showed particular promise as a sparassol producer.

Conclusion

The production of phenol compounds appears to be linked to constitutive processes of Sparassis metabolism, with production intensity and accumulation varying by strain, conditions, and cultivation time. The study identified strain LE-BIN 2902 as a promising candidate for sparassol production.
