Franklin, WI. – Microbial Discovery Group (MDG), a R&D driven Bacillus fermentation company, announces plans for expansion to accommodate continuing growth and future developmental plans. Answering increasing demand for their microbial-based products and solutions, MDG will execute short and long term expansion efforts in alignment with their business growth priorities which will provide capacity for increased sales, production, and employees. A phased expansion approach will take place throughout 2017-2019 both within and beyond the existing 20,000 sq. ft. Franklin facility. The Franklin facility is currently gaining additional fermentation and drying capacity that is projected to be operational in August, 2018. The Franklin expansion alone will bring MDG’s revenue capacity to roughly $25M USD. With demand projections continuing to climb, MDG has set strategic plans to creating a future of $50M in revenue creation. MDG is moving its powder and liquid blending operations to a 40,000 sq. ft. building in Oak Creek, WI to create space for the new fermentation capacity and future expansion needs. In 2019, the Oak Creek facility will feature additional offices and laboratories to house an added 40 employees who will be hired over the next 3-5 years. All phases contribute to the companies’ ability and readiness to serve their customers. MDG’s […]

I am amazed by all of the studies and tests taking place in our lab to develop new and improved products. This really keeps our customers on the cutting edge of new technology. Just when I think we have found the final solution to a major problem area for one of our partners, we continue working to find something even better. It seems like everyone at Microbial Discovery Group has an obsession with solving problems, while others just seem to stop working after they find one solution that works pretty well. This year alone, we have developed so many new products, some we currently offer, and others should be available shortly. Don’t hesitate to ask if we have a product that works in a particular situation, you may be very surprised to find out that we have it currently on stability testing. I look forward to your call! – Michael Davis

According to the EPA, about 1 in 5 US homes depend on septic systems, and with the uptick in professionals working from home, septic tank maintenance and backup prevention tips are among some of the top online searches. Septic service companies are in high demand, more people are home adding materials to the systems’ limited capacity, and high amounts of disinfectants are being used; all of which, are putting home septic systems to the test. Thankfully, there are many proactive measures you can take to prevent an untimely backup. Top 5 tips to protect your septic system: Recognize your septic system is a biological system. Septic systems are functioning ecosystems filled with living microorganisms. These microorganisms work to keep your septic systems clear by breaking down human waste and toilet paper. Be mindful of the disinfectants, sanitizers, house cleaners, and chemicals. Highly concentrated bleach products, other disinfectants, and strong chemical-based drain cleaners can be harmful to septic biology. Septic system biology tends to be overexposed to harsh chemicals through the improper disposal of toxic chemistries such as engine oil and paint cleaners, as well as the overuse of strong chemical products. Only flush human waste and toilet paper. Much too often, wipes, […]

If your customer is smelling the result of decomposing organic matter, such as feces, other bodily fluids, dairy, meat, or plant-based materials, chances are they’re smelling a Volatile Fatty Acid (VFA). Figure 1. Common odors associated with VFAs. VFAs are organic acids produced by the microbial metabolism of biomass and food waste; such as dietary fiber, starch, protein, and amino acids. To beat these odors, certain strains of Bacillus have the ability to breakdown VFAs, thereby helping to reduce the problem at the source. At Microbial Discovery Group (MDG) an in-vitro study was conducted to measure the growth of our Bacillus strains in the presence of VFAs. SporActiv® Foundation was grown in media containing acetate and a combination of common VFAs found in the I&I market; acetate, butyrate, propionate, valerate, isovalerate, and isobutyrate. These VFAs were chosen because of their known connection to unpleasant odors.   RESULTS Figure 2. Increase in growth of SporActiv® Foundation grown in media containing acetate, or a combination of six VFAs. The results show that growth of SporActiv® Foundation Bacillus increased by more than 50% when acetate was present, and by more than 100% when the six VFAs were present (Figure 2). The addition of these VFAs allowed for increased Bacillus growth, indicating the […]

As consumers, we constantly search for a particular level of quality in everything we purchase. From toilet tissue, cleaning products, or microbial products, there is an expectation to deliver upon standards. Those standards are established through trust, and it’s incredibly important to uphold that trust to keep the customer coming back. MDG is passionate about delivering a product that meets that high and personal standard. A standard we achieve each time through our trusted processes and quality control (QC) testing. Compatible ingredients such as preservatives, dyes, surfactants, and fragrances are recommended from a list of stability tested ingredients guaranteeing a two-year shelf life. Once an existing or newly formulated product is created, its blended and the SPECs (specifications) are tested via our quality control lab. SPECS such as the effective amount of bacteria for the application, factors that prevent spoilage (pH and preservatives), and making sure there are no unwanted organisms such as pathogens present in the final product. The SPECS are essential to consider the level of quality when QC checks a concentrated Bacillus product, see below:   CFU: AKA, CFU/g or ‘Colony Forming Units’ per gram.  This value represents the actual number of culturable cells in a gram of material. This […]

MDG has completed its obligation to notify under the New Substance Notification Regulations (Organisms) for Environment and Climate Change Canada (ECCC) on strains of Bacillus. Once imported into Canada the strains will be added to the Domestic Substance List (DSL) increasing MDG’s product offering into Canada. Adding these additional strains to the DSL will allow for more products from MDG to be available, focusing on core brands, Biotifx® for Wastewater Treatment and SporActiv® for the Industrial and Institutional market, to be sold in Canada. What is the Domestic Substance List: The Domestic Substance List (DSL) is an inventory of all chemical (and microorganism) substances manufactured in, or imported into, Canada on a commercial scale. 1 The DSL does not cover microorganisms that are regulated by other agencies such as those in food, feed, and fertilizer. The list was originally published in May 1994 with 23,000 substances included. 1 Today the list is at 28,000 substances, including microorganisms, and growing. 3 MDG Bacillus Strain on the DSL: Microorganisms, like MDG’s Bacillus, already exist on the DSL. Each microorganism strain is a unique substance, and each must be reviewed on its own merits for safety. The New Substance Notification (NSN) risk assessment includes general information on the strain, its ecological and biological characteristics, […]

Outdoor activities like RV camping are an ideal way for travelers to escape indoor isolation. It’s all about packing up the necessities and hitting the open road. Living out of an RV camper for any amount of time will likely include eating, sleeping, and using the bathroom. These are some of the essentials that are all part of the experience. Imagine being a traveler; Sitting around the campfire, cooking outdoors, and hiking are just a few of the fun activities to enjoy. However, smelling sewage while sitting in your RV, drinking that morning cup of hot coffee looking over a beautiful scenic view is not ideal. Luckily, MDG is here to ensure these odors don’t ruin the RV experience! As a cleaning solutions manufacturer and/or distributor, you may know that there are three main types of RV septic tank treatments on the market: Chemical-based Biological-based Combination of chemical and biological-based These all have their time and place for when they’re best used and are discussed in detail below, but treatments that contain Bacillus are superior for long-term effectiveness and are something to consider if you aren’t already offering. Chemical-Based Treatments Chemical-based products have been used for years and often include strong compounds […]

It’s been a tough few years for the pulp and paper (P&P) industry. With an increase in foreign competition and a lowered demand for paper, many facilities have had to tighten their belt. One of the most probable victims of these cuts are the wastewater treatment systems. Wastewater needs to be cleaned while sludge continues to build up. What was once full capacity-lagoons ready to handle a lot of wastewater are now full of sludge. With limitations on a budget, land to build more lagoons and time allotted for dredging, the sludge and holding capacity concerns have fallen to the wayside to be dealt with another time. Maybe that time is now.  Those full lagoons are rearing their ugly heads and maybe you’re realizing that you shouldn’t have ignored that sludge after all. You have no time to build an extra lagoon or dredging may not be a quick enough or a financially viable option. Enter a third possibility: Bioaugmentation. With the help of hardy Bacillus bacteria, you can treat the incoming sludge as you go, while also reducing your current sludge blanket. With bioaugmentation, you can experience results over time and restore treatment capacity. This buys you time and improves water treatment simultaneously. Pulp […]

In the large-scale liquid bacterial fermentation world, there are two primary ways to grow bacteria: as individual strains or in combination with others. At Microbial Discovery Group, we grow one strain at a time as it has served us well over the past decade. Truth be told, if I could find a way to grow multiple strains in one batch that was produced through a consistent process, resulting in high yield and uniformity in strain ratio, was guaranteed for purity, and ensured maximum sporulation – I would use it for our wastewater treatment products. Over the years we have experimented in finding different ways to accomplish this large task, but sadly none of the results measured up against our 5 criteria for success. Therefore, we are leveraging our expertise in growing one strain at a time to consistently meet our customers’ needs. Growing one strain at a time ensures: Highest strain yield Guaranteed purity Process consistency Uniformity of strain ratio Maximum % sporulation Highest Strain Yield Throughout the years we have found ways to get extremely high yields when growing one strain at a time. I believe our record is just under 3 x 1010 CFU/mL in the fermentation broth. I […]
