BECAUSE the bacteria in the BACILLO STOPER PRODUCT directly and indirectly affect plant growth.
Direct promotion of plant growth includes:
- Production of plant hormones (auxins, gibberellins, cytokinins), ACC deaminase
- Improving the availability of nutrients (nitrogen fixation and phosphate solubilization), synthesizing organic acids and phosphatases that will convert inaccessible phosphorus into a form accessible to plants. Potassium, which is trapped in the soil in the form of aluminosilicates, becomes available to plants thanks to the activity of bacteria from the Bacillus genus.
Indirect promotion of plant growth includes:
- Biological control of plant pathogens through root surface colonization,
- Production of extracellular lytic enzymes, siderophores, antibiotics, hydrogen cyanide, or activation of plant defense mechanisms. Lipopeptides form a biofilm on the plant surface, preventing pathogen development, while the enzyme subtilin interferes with pathogen growth through its strong antibiotic action. By synthesizing antibiotics, bacteriocins, fengycin, surfactin, and iturin, they destructively affect fungal hyphae. Fengycin is a cyclic lipopeptide that forms phosphatidylcholine—a stable oligomer—on the outer side of the fungal hyphae cell wall, affecting the function of the cell wall itself, resulting in wall destruction.
