What Microbial Discovery Group (MDG) Sells
Microbial Discovery Group (MDG) is a Bacillus fermentation manufacturer, and for wastewater it sells the Biotifx product line: Biotifx 40B, a water-soluble packet; Biotifx AN, formulated for anaerobic digesters; Biotifx BLOCK, a mesh-bag hanging block for collection systems; Biotifx Liquid Max and Liquid Max FRZ; Biotifx ULTRA; Biotifx SR 10X; and, per MDG’s own product catalog, Biotifx NITRIFY and Biotifx AMMO for ammonia control. As MDG’s website describes it, September 2026, the Bacillus strains in Biotifx were selected from a large internal strain library for their “enhanced ability to degrade an extensive range of organic substrates,” including FOG and odor-causing compounds, and are combined with a proprietary blend of micronutrients and biostimulants. For ammonia, MDG describes Bacillus that use the nitrogen in ammonia for bacterial growth, and separately describes Biotifx NITRIFY as containing a blend of classical nitrifiers. No enzymes, fungi or inert carrier are named as active ingredients; the products themselves are bacterial and nutrient blends sold in liquid, powder or solid form.
MDG reaches most of the market through a distributor and dealer network rather than selling directly, and for septic and residential use it positions itself as a supplier to the businesses that sell to homeowners, not a direct-to-homeowner brand. Alongside the products, MDG runs a service approach it calls C.A.T.E.R.: Consult, Analyze, Treat, Evaluate, Report.
Where Microbial Discovery Group Is the Better Fit
Microbial Discovery Group would honestly be the better fit for a facility that wants one distributor-sourced product line spanning odor, FOG, sludge and ammonia, including a nitrifying-strain product built for a specific ammonia problem, or a mesh-bag block and dissolving packet for simple, no-equipment dosing in a lift station or small tank. It also fits a business that wants to become a bioaugmentation reseller, working with MDG’s training and technical support rather than buying a recurring service directly.
How DRP Accelerator Differs
DRP Accelerator starts from a different point of intervention. Where Biotifx adds Bacillus strains and a nutrient blend meant to help those strains establish, DRP Accelerator adds nothing biological: it is an inorganic compound that carries usable oxygen to the bacteria already living in the wastewater. We add no bacteria, no enzymes and no carrier material.
That difference changes what happens to hydrogen sulfide. MDG describes Bacillus that digest ammonia and odor-causing compounds once they are present and active in the system. DRP Accelerator works earlier: with usable oxygen available, the native bacteria stop drawing it from sulfate in the first place, so hydrogen sulfide is not formed rather than digested or masked after it already exists. The same oxygen supports the aerobic bacteria that digest fats, oils, grease and organic sludge, work an oxygen-starved system leaves undone.
Delivery differs too. Biotifx ships as a packet, a hanging block or a liquid concentrate, dosed by hand or through a distributor’s recommended schedule. DRP Accelerator arrives dry, is mixed and activated in a tank on site, and drips continuously into the flow, dosed as far upstream as water and power allow. Nothing of the accelerator is left behind: it is consumed as the bacteria use its oxygen, with no chemical additives remaining downstream. The program runs as a monthly, measured service built around a baseline and follow-up readings rather than a packaged product bought and re-ordered on a label schedule.
Microbial Discovery Group and DRP Accelerator, Side by Side
| Factor | Microbial Discovery Group (Biotifx) | DRP Accelerator |
|---|---|---|
| What it adds | Bacillus bacteria strains and a nutrient blend | Usable oxygen for bacteria already present |
| When it acts | After: added organisms establish, then digest ammonia and odor-causing compounds | Before: bacteria have oxygen before they would strip it from sulfate |
| What stays downstream | Added Bacillus culture and nutrient residue, re-dosed on a schedule | Nothing; the compound is consumed as bacteria use it |
| Delivery | Packet, hanging block or liquid concentrate, mostly through a distributor network | Dry product mixed and activated on site, dosed continuously upstream |
| Measurement | Qualitative results reported through MDG’s own C.A.T.E.R. service process | Baseline and follow-up readings as part of the service |
| Best fit | A facility wanting one distributor-sourced line across odor, FOG, sludge and ammonia, or simple no-equipment dosing | A lift station, force main or lagoon needing an upstream, continuous, measured program |
Which Question to Ask About Your System
The honest answer depends on the system in front of you, not on which product is being sold. The question worth asking is where the intervention happens: does the fix need to add something to the water and hope it establishes, or change the conditions the bacteria already there are working under? A small tank or a contained ammonia problem with easy hand access is often served well by a packaged Bacillus product like Biotifx. A lift station, force main or lagoon where hydrogen sulfide keeps coming back, where FOG and sludge both need attention, and where someone has to show a measured trend rather than an impression, is where DRP Accelerator’s upstream, continuous, oxygen-based approach earns its place.
Summary
- Microbial Discovery Group sells Biotifx, a Bacillus and nutrient blend line reaching most of the market through distributors, sold as packets, hanging blocks and liquid concentrates for odor, FOG, sludge and ammonia. DRP Accelerator supplies usable oxygen to the bacteria already present, dosed continuously and measured as a monthly service.
- A distributor-sourced product line across several problems, or simple no-equipment dosing in a small tank or lift station, usually favors Biotifx. A system where hydrogen sulfide keeps returning and someone needs a measured, upstream, continuous program usually favors DRP Accelerator.
- The two approaches differ in what they add: Biotifx adds organisms and nutrients meant to establish in the water; DRP Accelerator adds no organisms at all, only usable oxygen, consumed as the bacteria use it, with nothing left downstream.
