MDG has the resources and production capacity to meet your custom fermentation needs, helping you create a high-quality microbial product for your formulations. With decades of experience in microbial manufacturing, our microbiologists, fermentation team, and production specialists are here to answer your questions and provide guidance to scale your strains with us. One important element of scale-up production is choosing which method to use for drying your product. At MDG, we offer two different drying methods: spray drying and freeze drying. Each drying process has its unique steps and merits, but either way, if you choose to dry, we can help you succeed. Read on to learn more about spray drying and freeze drying, so when you partner with us, you’re ready to begin the process! Different Custom Fermentation Drying Methods Method One: Spray Drying Spray drying is a method that uses heat and airflow to produce the final powdered culture from spore slurry. Before beginning the large-scale process, our production specialists will conduct testing with our pilot spray dryer. These trials typically include seeing how different flow and bulking agents will affect the outcome of the final powder product. During this period, we also determine the capture rate and […]

Whether you’re a manufacturer just entering the microbial cleaning world, or you’ve been using bacterial ingredients in your industrial and institutional cleaning products for a while, it’s always important to go over the fundamentals of how these ingredients work. Let’s explore a few common questions about Bacillus and discover how MDG can be your trusted partner in the world of microbial ingredients. What is Bacillus? Bacillus is a bacteria species that excels at reducing excess organic buildup and unwanted odors in a multitude of applications. At MDG, we specialize in Bacillus, and our R&D teams are continuously innovating new ways to harness the power of bioaugmentation with Bacillus for waste treatment and odor mitigation.  How are Bacillus strains able to reduce odors? Bacillus use certain odor-causing compounds as a food source. When Bacillus strains are added to a system with excess odor or sludge buildup, they consume the unwanted material, therefore reducing the problem. For example, when Bacillus-based products are applied in a septic tank, the bacterial activity in the native environment is increased, leading to more digestion of built-up solids and fewer odors. Additionally, Bacillus can assimilate and incorporate substances like nitrogen, preventing them from being released as odorous […]

We partner with distributors around the globe to help their customers achieve cleaner wastewater. Based in the United States, our skilled technical service and sales teams are knowledgeable about wastewater treatment markets throughout the world, including the Latin American region. Learn about the wastewater treatment solutions we offer in light of Latin America’s increasing regulations and find out how you can become our partner! Market concerns… Water quality can be a significant problem for wastewater treatment facilities in Latin America. Government regulations surrounding COD, BOD, and nitrogen have increased across the region for facilities like lagoons and activated sludge systems. This is because, to combat the current scarcity, many places in Latin America are recycling water and depending on treatment facilities to clean it. Some facilities are struggling to keep up with the changes, particularly in situations with old equipment and a lack of proper infrastructure. Latin American wastewater treatment facilities need an affordable and effective solution that cleans well and gets their wastewater up to standard. With […]

When you partner with MDG for your custom fermentation needs, you can be confident that our microbiologists and production experts are committed to delivering a final culture that fits your specifications. We follow our Trusted Process closely, fostering success for our customers. But what does that process look like? Read on to discover what our custom microbial fermentation process entails, from pilot scale to commercialization.   Part One: Rapid Scale-Up When you begin the custom fermentation process with MDG, your Bacillus strain will go through a process development program. This stage typically takes about twelve weeks to complete. The process development steps are as follows:   MDG receives your strain in our in-house labs. Our microbiologists streak your strain to ensure purity. An initial growth screen begins, during which our specialists test your Bacillus strain’s growth ability on a multitude of different media. Growth media is narrowed down to a few top choices, and additional testing is performed to find the optimal media for your strain. Once we’ve found the right growth media, we will grow your strain on a pilot scale, harvest and dry the culture, and send it to you for evaluation.   After you give your approval […]

At MDG, we are Bacillus experts with over 20 years of experience growing pure cultures for our customers. We are continually honing our methods to find the most effective, efficient way to create quality microbial ingredients, and one contributing factor is purity testing. From performing testing through strain typing methods to producing and selling only single-strain tanks, let’s explore the process of purity testing to find out why creating effective microbial products happens one strain at a time. What is strain purity testing, and how is it done? Strain purity testing is the process of checking a growing Bacillus culture to ensure it is a match for the target strain. Testing can also confirm that there are no non-target organisms present in the culture. Purity testing can be done in a multitude of ways. We have a variety of genomic methods at our disposal that allow for thorough, efficient testing of each Bacillus culture. Testing is conducted at several steps of the process, including: Seed bank Inoculation flask Fermentation tank Dried culture (finished product) Monitoring the purity of the culture at multiple points allows us to catch and correct any potential errors as soon as possible and keep the process […]

As summer begins, outdoor events, construction projects, and gatherings become much more frequent, and portable toilets usually found at these locations can present a significant odor challenge. Managing those odors is essential for maintaining both public and environmental health. At MDG, we have extensive experience in microbial technologies, and our advanced biological solutions provide an innovative approach to tackling these odors effectively. Odors Have an Impact Odor control affects not only user comfort but also the overall acceptance and viability of portable toilets at public and commercial venues. When not properly addressed, the odors that portable toilets cause can cast the event—and potentially the portable sanitation suppliers—in a negative light. Effective odor management, on the other hand, can enhance customer satisfaction and bolster the reputation of distributors and event organizers alike. The Impact of Our Products Microbial solutions are a great way to combat odors, particularly in the application of portable sanitation. Unlike traditional chemical options, our biologically based treatments utilize Bacillus to digest waste materials, effectively reducing odors. A solution like this not only minimizes unpleasant smells but also contributes to a healthier environment by reducing the reliance on harsh chemical agents. MDG’s microbial products are also created with […]
