Summary
This research explored how adding selenium-enriched yeast to mushroom cultivation can create nutritionally enhanced mushroom supplements. The medicinal mushroom Coriolus versicolor was successfully grown with high levels of selenium and other beneficial minerals, potentially creating a more nutritious food supplement.
Impacts on everyday life:
• Provides a new way to create selenium-enriched natural supplements
• Offers potential for more nutritious functional food products
• Demonstrates a natural method for mineral enrichment of food
• Could help address selenium deficiency through dietary supplements
• Shows promise for developing new antimicrobial products
Background
Coriolus versicolor is a medicinal mushroom with potential applications in functional food and supplements. Understanding its ability to accumulate selenium and other minerals during cultivation is important for developing enhanced nutritional products.
Objective
To examine the ability of Coriolus versicolor to grow and accumulate selenium during submerged cultivation in selenium-fortified medium using commercial selenium yeast as a supplement.
Results
The mushroom demonstrated high selenium accumulation capacity, reaching 970 and 1,300 µg/g of dry mycelium weight for samples enriched with 10 and 20 mg Se/L respectively. Selenium addition significantly increased biomass yield. Strong positive correlations were found between selenium content and other minerals (Fe, Cu, Mn, Sr). Methanol extracts showed enhanced inhibitory effects against Gram-positive bacteria with MICs between <0.3125 and 40 mg/ml.
Conclusion
Selenium yeast supplementation successfully produced mushroom biomass with high selenium content and enhanced mineral composition, suggesting potential applications as a novel food supplement with improved selenium bioavailability.
