Our Mission

REAL SCIENCE

REAL SCIENCE MATTERS; IT IS OUR FOUNDATION

Microbial Discovery Group is a Bacillus manufacturer. Others might look and act like they are the grower, but at MDG we are a grower. At Microbial Discovery Group, we stand behind the products we produce. Our products are born from rigorous research and development, testing, and validation before we ever go to market. When we say our products work for your application, we have the science to back it up.

Our entire operation, including our in-house research and development production facilities, has been designed around these core beliefs and principles, resulting in an accountable and advantageous environment that empowers us to:

  • Leverage novel technologies
  • Experiment with new ideas
  • Apply sound science, informed practices, and quality-tested protocols to our work
  • Better-serve the unique needs of our customers

This is our driving force behind all that we have done and will do as we continuously learn, adapt, and grow alongside our valued partners.

Real Science matters; it is our foundation.
