Yeast extracts are concentrated sources of the water-soluble fraction of autolyzed Saccharomyces cerevisiae cells, derived from high-quality primary-grown baker’s yeast. These animal-free supplements provide essential vitamins, amino acids, peptides, and carbohydrates, making them ideal for fungal culture, microbial fermentation, and mycelium growth. Lab-grade purity ensures consistency and efficiency in scientific and industrial applications.

Recommended Yeast Extract Usage in Mushroom Cultivation

The optimal yeast extract concentration varies based on the mushroom species and culture medium, typically ranging from 0.1% to 1% of the total volume:

🔹 Liquid media (e.g., shake flask cultures): 0.5 to 1 g/L
🔹 Solid media (e.g., agar for mycelium growth): 0.1 to 0.5%

For enhanced mycelium development, combine yeast extract with malt extract or agar-agar for a nutrient-rich and supportive growth environment. Or, try our pre-mixed Malt Extract Agar (MEA) for a convenient, ready-to-use solution!
