Why Bacillus? A Closer Look at this Powerful Probiotic Ingredient

Lactobacillus and Bifidobacterium are two genera of vegetative bacteria whose historic success in probiotic applications has made them a common ingredient in many final products. However, Bacillus, a spore-forming bacteria, is becoming increasingly more popular due to its stability in diverse applications and the new range of functionalities it offers. Exciting discoveries about Bacillus have opened a fast-growing area of the human health marketplace. Discover what makes this microorganism so powerful and how MDG can help you use Bacillus to achieve success.

What are the benefits of using Bacillus in probiotics?

Many of Bacillus’s advantages in probiotic products stem from its spore-forming nature. Forming spores allows Bacillus bacteria to maintain their efficacy and survive extreme environmental conditions that vegetative bacteria like Lactobacillus and Bifidobacterium may not be able to tolerate. This hardiness leads to a number of benefits, including:

  • Greater stability: Because of its ability to form spores, Bacillus is highly stable, unlike Lactobacillus or Bifidobacterium. These two alternative, vegetative bacteria are non-spore-forming, so they typically need to go through an encapsulation process to reach the same level of stability, which can be expensive for probiotic manufacturers.
  • Longer shelf life: With the stability of Bacillus, you can sell your product for longer without worrying about it losing effectiveness.1 On the other hand, vegetative, non-spore-forming bacteria like Bifidobacterium and Lactobacillus typically require a specific environment to maintain their efficacy, and it could be costly to create the right conditions for them in a storage or retail environment.
  • Better viability through the gut: When Bacillus is in spore form, it can survive the low-pH, high-heat environment of the stomach, remaining detectable and effective.2 Bacillus also germinate efficiently in the upper small intestine, allowing ample time for them to have an effect during the remaining passage through the gastrointestinal tract. Conversely, some species of Bifidobacterium have been shown to become undetectable in stomach acid after just one hour,3 while another study evaluating certain Lactobacillus species’ ability to survive in environments like the stomach found that the tested populations experienced a 73%–100% decrease in count.4
  • Wider range of applications/delivery methods: Depending on your chosen application, the Bacillus in your final formulation may need to survive harsh production processes that usually result in significant count losses for vegetative bacteria. For example, manufacturing a gummy probiotic necessitates putting the product through extreme heat and cold in quick succession. Bacillus spores are able to survive this process and maintain their effectiveness as a probiotic for a significant amount of time after production is complete.5
