Microorganisms for Plants

Microorganisms used by Custom Biologicals


I’m often asked how we choose the microorganisms for plants that we use in our products. I’ll use this post to describe the process we use to choose our bacteria and fungi used in our biological products.

Microorganisms for Plants Criteria

Custom Biologicals uses six criteria when choosing microorganisms for our products. Microorganisms for plantsHere’s the list:

  • Safety First – ALWAYS
  • Non- Pathogenic – do not cause disease
  • Natural – Not GMO (NOT genetically modified organisms)
  • Non-Opportunistic
  • All from the ATCC (American Type Culture Collection)
  • Proven Benefits on 40+ crops

Safety is always our first concern and you’ll notice that the first four points touch on safety. We don’t use any known human pathogens. All of our products contain microorganisms that are non-opportunistic. That means that they don’t cause disease even in a compromised host.

All of our products are derived from microorganisms we have received from the American Type Culture Collection (ATCC). The ATCC is a repository for microorganisms. Many of these have been studied by universities and companies worldwide. This allows us to choose the species that are most beneficial for the task at hand. It also allows us to monitor thousands of field trials on these organisms around the globe greatly expanding our knowledge base.

Finally, we choose our organisms based on their proven benefit to crops. We then test the products both in our laboratory and in our own field tests.

Using this method, we determine which microorganisms for plants to use in our products. Currently, we use both beneficial soil bacteria and beneficial soil Trichoderma species.
