Custom Fermentation
As a Bacillus manufacturer, we specialize in growing pure single-strain Bacillus cultures. Currently, we have 55,000 liters of fermentation capacity and production capabilities.
Grow Your Strain with Us!
At MDG, we take pride in the microbial strains we manufacture and grow for our customers. With our dedication to Real Science and a Trusted Process developed over our 20+ years of experience, we deliver Proven Success to our partners. When you choose MDG, you can expect your organism to undergo:
- Isolation: We test for strain purity and ensure that the sample we’ve grown and streaked out in the lab matches your intended strain.
- Optimization: To maximize efficiency throughout the process, we identify optimal growth media and conditions for your organism using our pilot-scale equipment.
- Growth: Our experts create single-strain tanks to ensure only the target organism is present in the final product.
- Commercialization: We specialize in scaling up strains for commercial success, partnering with you along the way to help improve processes and increase yields.
While we’re experts in Bacillus, we can also work with non-Bacillus organisms. No matter what your needs are, we are dedicated to helping you go from strain to sales efficiently, effectively, and economically.
