Fully Soluble Yeast Cell Wall Promotes Photosynthesis Foliar Spraying Biologically Active Fertilizer

Yeast cell walls are produced by using Saccharomyces cerevisiae as the strain, fermenting it in a liquid pure culture, followed by autolysis and hydrolysis catalyzed by exogenous enzymes, then separation and spray drying.

1. Plant Immune Activation and Disease Resistance

   • β-Glucan: Activates the plant's innate immune system (e.g., induces PR proteins and plant defensins), enhancing resistance to fungal diseases (e.g., rice blast) and bacterial diseases (e.g., bacterial wilt).
   • Application Example: Foliar spraying of yeast cell wall extract (0.1% concentration) can reduce the incidence of gray mold disease in tomatoes by 30%-50%.

2. Soil Improvement and Microbial Regulation

   • Mannan Oligosaccharides (MOS): Serve as prebiotics to promote the proliferation of beneficial soil bacteria (e.g., nitrogen-fixing bacteria, actinomycetes) and inhibit pathogenic bacteria (e.g., Fusarium).
   • Soil Remediation: Adsorbs heavy metals (e.g., cadmium, lead), reducing plant uptake and enhancing the safety of agricultural products.

3. Promotes Crop Growth
   Stimulates root development and increases nutrient absorption efficiency (nitrogen and phosphorus utilization improves by 15%-20%).
   Example: Adding 1% yeast cell wall to rice seedling substrates increases tiller number by 10%-15%.

1. Enhanced Immunity and Stress Resistance

   • β-Glucan: Activates macrophages and the complement system in fish and shrimp, improving resistance to viral (e.g., WSSV) and bacterial (e.g., vibrios) infections.
   • Experimental Data: Adding 0.2% yeast cell wall to the feed of Pacific white shrimp increases survival rates by 20% and reduces the feed conversion ratio (FCR) by 0.3.

2. Gut Health and Digestive Promotion

   • MOS: Competes to block the adhesion of pathogenic bacteria (e.g., Aeromonas) in the gut, promoting the colonization of beneficial lactic acid bacteria.
   • Enzyme Activity Enhancement: Stimulates the secretion of digestive enzymes (proteases, amylases), improving feed conversion rates.

3. Water Quality Regulation and Detoxification
   Adsorbs ammonia nitrogen and nitrites in the water, reducing the frequency of water changes.
   When used in conjunction with probiotics, it can lower the risk of blue-green algae outbreaks.

1. Natural Alternatives to Antibiotics

   • MOS: Blocks the adhesion of E. coli and Salmonella, reducing diarrhea rates in piglets by 40%-60%.
   • β-Glucan: Enhances the intestinal immune barrier, alleviating the decline in milk production due to heat stress in dairy cows.

2. Improved Growth Performance and Meat Quality

   • Broilers: Adding 0.1% yeast cell wall to feed increases daily weight gain by 5%-8% and raises the proportion of unsaturated fatty acids in the muscle.
   • Layer Hens: Increases eggshell strength, reduces breakage rates, and lowers cholesterol content in egg yolks by 10%-15%.

3. Reduced Environmental Pollution
   Regulates gut microbiota balance, decreasing ammonia (by 30%) and hydrogen sulfide emissions from manure.
   Example: Using yeast cell wall additives in pig farms reduces manure treatment costs by 20%.

1. Recommended Usage:

   • Agricultural foliar spraying: 0.05%-0.2%
   • Aquaculture feed: 0.1%-0.3%
   • Livestock feed: 0.05%-0.15% (excessive amounts may inhibit feed intake).

2. Compatibility and Synergy:

   • Use with beneficial bacteria (e.g., Bacillus subtilis) and acidifiers for better results.
   • Avoid simultaneous use with strong oxidizers (e.g., potassium permanganate) or broad-spectrum antibiotics.
