Summary
This study compared growing the medicinal mushroom Ganoderma tsugae on sterilized versus non-sterilized larch wood in a forest setting. Researchers found that non-sterilized wood actually produced mushrooms with higher levels of beneficial compounds like triterpenoids and polysaccharides, while requiring less processing and cost. These findings suggest that farmers can use a simpler, less expensive cultivation method while still producing high-quality medicinal mushrooms.
Background
Ganoderma tsugae (hemlock reishi) is a medicinal mushroom used traditionally in East Asia for over 2000 years. Due to limited natural availability and increasing global demand, commercial cultivation methods have been developed. This study addresses the need to optimize substrate treatments for improved yield and bioactive compound content.
Objective
To evaluate the differential impacts of sterilized versus non-sterilized larch wood substrates on the growth, yield, and bioactive constituent content of Ganoderma tsugae cultivated in a forest-like environment.
Results
No significant differences were found between sterilized and non-sterilized substrates regarding agronomic traits. Non-sterilized substrates (Y2) showed optimal mineral content and bioactive compounds, particularly higher triterpenes and polysaccharides in mature fruiting bodies. Wild strains were markedly less effective than cultivated strains in bioactive component accumulation.
Conclusion
Non-sterilized larch logs (Y2) represent an excellent substrate for commercial G. tsugae cultivation, providing equal yields with higher bioactive content and cost savings. The findings provide practical guidance for mushroom growers seeking to enhance production quality and profitability.
