Source of Strain

Derived from a high-yield Bacillus subtilis natto strain exclusively screened and genetically improved by UC Davis. This advanced strain results in:

• Higher content of γ-PGA.
• Enrichment in beneficial metabolic products, enhancing agricultural applications.

Additionally, the precision fermentation process ensures:

• Lower molecular weight, making it more suitable for agricultural production.
• Enhanced absorption by crops, leading to faster effects and better outcomes.

Production Process

Bacillus subtilis natto → Glutamic Acid → Fermentation Control → Metabolic Products

Key Agricultural Benefits of γ-Polyglutamic Acid

1. Outstanding Water and Fertilizer Retention

• Forms a protective layer on root hairs, serving as an optimal platform for nutrient and moisture transport.
• Enhances the dissolution, storage, transport, and absorption of fertilizers.
• Prevents the precipitation of sulfates, phosphates, and oxalates with metal elements, ensuring better absorption of phosphorus, calcium, magnesium, and trace elements.
• Promotes root development and improves fertilizer efficiency.

2. Soil pH Regulation

• Exhibits excellent buffering capacity, balancing soil pH.
• Prevents soil acidification caused by prolonged use of chemical fertilizers.

3. Chelation of Toxic Heavy Metals

• Effectively binds and reduces the toxicity of heavy metals in the soil, improving soil health.

4. Enhanced Plant Disease Resistance & Stress Tolerance

• Boosts resistance against drought, flooding, cold, and diseases.
• Reduces soil-borne diseases, improving overall crop health.

5. Promotes Crop Growth & Increases Yield

• Enhances crop growth vigor and overall productivity.
• Increases yield by 15-30% in crops like tea, fruits, and vegetables
