Edible fungus cultures made from starters have four advantages

The advantages of edible fungi culture materials produced using a starter are evident in four main aspects: First, the material temperature changes significantly. When using a fermentation agent, the temperature of the culture medium rises rapidly to above 60°C. For example, with the Kinpo fermentation agent, the temperature can reach 60–70°C within two or three days. This high temperature not only kills harmful bacteria but also eliminates most of the eggs that may be present, ensuring a cleaner and safer growing environment for the mushrooms. Second, there is a noticeable change in the microbial population. The fermentation agent promotes the rapid multiplication of beneficial microorganisms such as bacteria, fungi, actinomycetes, and nitrogen-fixing bacteria. These microbes increase in number dramatically—especially actinomycetes, which can be over 100 times more than in secondary fermentation. With such a large population, these beneficial microbes "preempt" space and resources, effectively limiting the growth of harmful or contaminating bacteria. Their activity also generates significant heat, causing the material temperature to rise quickly and remain elevated for a longer period. In addition, the antibiotics produced by these beneficial microbes act as a natural barrier, preventing the return of unwanted bacteria. Third, the nutrient composition of the culture material undergoes favorable changes during fermentation. As the starter's microbial population works, cellulose-decomposing fungi and actinomycetes multiply, gradually breaking down cellulose and increasing the level of soluble sugars. This improves the carbon-to-nitrogen ratio, making the material more suitable for mushroom mycelium growth. Additionally, free proteins are converted into mycelial protein, which is more easily absorbed by the mushrooms. Using a product like Golden Baby Ferment can boost the yield of edible fungi by 20–30%. Fourth, the use of a starter expands the range of raw materials and allows for more efficient use of manure. Traditionally, cotton husk is the primary material used in mushroom cultivation, while crop stalks are often burned, causing environmental pollution. This happens because conventional fermentation methods are incomplete, leaving cellulose undegraded and difficult for mushroom mycelium to absorb. With a starter, this issue is resolved. Different types of manure, such as chicken and duck dung (hot manure rich in nutrients), cow dung (cold fertilizer with lower nutrients), and pig or silkworm dung (rich in nutrients but cold), can all be used effectively. Conventional methods often lead to pests or "burnt bacteria" problems, but the starter helps prevent this. With the rising cost of bran and cake fertilizers, using a fermentation agent to replace them with manure is a cost-effective way to enrich the nitrogen source of the culture medium. Fermentation also allows for greater use of manure, reducing waste. Even failed buckwheat or raw material bags, contaminated materials, or unused mushroom sticks from other species can be mixed with fresh material and still be used after treatment with the starter. This approach turns waste into valuable resources, allowing for the reuse of materials. Furthermore, the starter enables the transformation of clinker into usable fermented material, which is particularly beneficial for growing mushrooms like oyster, white, shiitake, and apricot mushrooms. This method reduces costs, minimizes environmental impact, simplifies operations, and increases overall production.
