Bacillus Subtilis Probiotics Powder


Are the probiotics you are using really heat-resistant and acid-resistant?
The core advantage of our agricultural-grade Bacillus subtilis strain (100 billion CFU/g) lies in its exceptional heat resistance and gastric acid tolerance. This strain possesses a unique spore structure that readily withstands the high temperatures of feed pelleting and the acidic conditions of the animal digestive tract, ensuring high viability rates reach the intestines and successful colonization. When applied in aquaculture production, it effectively enhances gut health and improves feed conversion efficiency, serving as an ideal solution for achieving both antibiotic-free farming and growth benefits.

Q: In aquaculture, what role does Bacillus Subtilis play?
A: In aquaculture systems, Bacillus subtilis functions as an efficient bioremediator and probiotic. Its primary role involves secreting a variety of extracellular enzymes to break down organic pollutants (e.g., residual feed and feces), thereby reducing the concentration of toxic ammonia nitrogen and nitrite in the water. Furthermore, by colonizing the water column and outcompeting harmful microorganisms for resources, it helps suppress the proliferation of pathogenic bacteria and algae, contributing to a healthier aquatic environment.
Q: What are the effects of mixing Bacillus Subtilis with other probiotic bacteria?
A: The combination of Bacillus subtilis with other probiotics can create synergistic effects, enhancing overall efficacy. For example, when used with lactic acid bacteria, they work synergistically to regulate the microenvironmental pH, promoting a balanced microbial community. In agricultural applications, its combination with photosynthetic bacteria is common; the latter provides organic acids, vitamins, and other growth factors for Bacillus subtilis, while the bacillus mobilizes soil nutrients. Together, they improve soil aggregate structure, enhance fertility, and support plant growth.
Q: How does Bacillus Subtilis play a role in agricultural planting?
A: In agricultural production, Bacillus subtilis serves dual functions as both a biofertilizer and a biocontrol agent. As a fertilizer, it mineralizes organic matter in the soil, converting complex nutrients (like organic nitrogen) into plant-available forms (such as ammonium nitrogen). As a biocontrol agent, it produces a spectrum of antimicrobial compounds (e.g., lipopeptides) that inhibit the growth of various soil-borne plant pathogens. This dual action not only helps control crop diseases but also improves soil health, leading to enhanced crop yield and quality.
