Cultural Characteristics and Log-Mediated Cultivation of the Medicinal Mushroom, Phellinus linteus

Summary

This research focused on developing methods to grow the medicinal mushroom Phellinus linteus, which has important anti-cancer properties but is rare in nature. The researchers determined the optimal conditions for growing this mushroom on mulberry logs, including temperature, humidity, and other environmental factors. Impacts on everyday life: • Enables commercial production of a valuable medicinal mushroom • Makes an important traditional medicine more widely available • Provides foundation for sustainable production of natural anti-cancer compounds • Helps preserve natural resources by reducing wild harvesting • Creates potential economic opportunities for mushroom growers

Background

Phellinus linteus is a medicinal mushroom that has been used in traditional Chinese medicine for centuries as ‘Sanghuang’. It exhibits antitumor and immunomodulating activities, with remarkable host-mediatory antitumor activity first described 40 years ago. Despite its high medicinal value and rare natural occurrence, artificial cultivation methods have remained largely unstudied.

Objective

To investigate the physiological characteristics required for mycelial growth and explore artificial production methods of P. linteus using Mulberry (Morus alba) logs.

Results

Optimal growth conditions were determined to be: mushroom complete medium (MCM), temperature of 30°C, pH 6.0, with sucrose as the best carbon source and potassium nitrate as the best nitrogen source. Sterilized short log inoculation was most effective, with 20cm logs at 42% moisture content providing best results. Logs required 12+ hours of sterilization and 5-6 months incubation. Fruiting body formation was optimal at 31-35°C with >96% relative humidity.

Conclusion

The study established optimal parameters for artificial cultivation of P. linteus on Mulberry logs, including specific growth conditions, inoculation methods, and environmental requirements for fruiting body development. This provides a foundation for commercial cultivation of this valuable medicinal mushroom.
