As experts in Bacillus, we’re dedicated to teaching our partners and potential customers about bioaugmentation and its benefits in the wastewater industry. Throughout the year, our microbiologists and technical support leads host webinars on a wide range of topics, from how to formulate quality microbial cleaning products to managing FOG in wastewater. One such webinar featured our technical support lead Josiah Menako speaking about strategies to improve TSS, COD, and BOD in wastewater. Keep reading for a recap and to find out how you can access the full webinar recording for free! Webinar Recap Menako began the webinar with a brief introduction to bioaugmentation, then dove into the specific variables of water quality: total suspended solids (TSS), chemical oxygen demand (COD), and biological oxygen demand (BOD). He explained that TSS can be either organic or inorganic depending on the wastewater application, and that the settling of TSS can cause capacity issues and add to COD/BOD in effluent water. Menako then went on to detail the relationship between COD and BOD. The remainder of the webinar was dedicated to our Proven Success demonstrated through case study data. Our wastewater technical support team often goes into the field with our distribution partners […]

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 […]

Para acceder a la versión en español, dar clic aquí. Our mission at MDG is to Feed, Clean, Save the World, and our partners are an important part of furthering that vision. 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 on the final […]

I was recently asked the WHY behind our current expansion. When I started to break it down, there were 4 key drivers that went into the new MDG facility design: Capacity expansion Reliability via redundancy Production of 50+ strains The expanding Bacillus marketCapacity expansion. This is the no-brainer for expanding. MDG was reaching 75% of our capacity, so we either had to expand or recognize there would be a future cap on what we could offer to our customers. With internal goals already in place to increase the reach of our offerings by 2020, we realized expanding was our best option. Reliability via redundancy. When you visit MDG you will see a very deliberate and intentional attempt at redundancy. To be reliable day in and day out, redundancy in equipment is vital. Let’s face it, equipment breaks down from time to time, but we don’t want our customers to have to suffer. At MDG, we have focused on setting up a model where we have multiple fermentors, centrifuges, freeze dryers, boilers, air compressors, chillers and sterilizers to back up our promise to deliver. We have a backup generator in place to guard against brown outs in electrical utility supply. We […]

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 […]
