Effectiveness of Probiotics International's formulated probiotic blend against pathogens

Auburn University study of the effects of Probiotics International's bacillus strains blend.
Evaluation conducted by Dr. Mark Liles, Department of Biological Sciences, Auburn University

Probiotics International engaged the internationally esteemed researchers at Auburn University to study the effects of using our probiotic blend. They were specifically looking for the benefits of:

  • improved feed conversion rate

  • reduced mortality

  • resistance to disease

  • faster growth to harvest size

  • improved water quality


The bacillus strains used in pureBacteria™ were tested and evaluated for their ability to inhibit the growth of various pathogens under laboratory conditions. Our pureBacteria™ contain a proprietary blend of four bacillus strains:

  • Bacillus subtilis produces amylase and proteases enzymes for clean water.

  • Bacillus pumilus produces anti-microbial compounds for disease control.

  • Bacillus Licheniformis is a bacterium that is widespread in nature and thought to contribute substantially to nutrient cycling due to the diversity of enzymes produced.

  • Bacillus Amyloliquefaciens is broadly used industrially to produce amylase and protease. Recent scientific studies have shown that this strain produces strong disease resistance and increased immune response within fish and shrimp.

Each of the four bacillus strains were observed to produce metabolites that inhibit the growth of pathogenic bacterial or oomycete pathogens. The antibiosis pattern observed was different for each of the four bacillus strains. This is attributable to each strain producing metabolites that defend against various aquaculture pathogens.
