Quick Answer: The Reencle microbe base is a living colony of thermophilic bacteria — including species like Bacillus and Actinomycetes — that biologically decomposes your food scraps into real compost. It is the engine of the entire system. Keep it healthy by feeding it steadily, keeping antibacterial agents away from it, and adding fresh base culture whenever decomposition slows. A well-maintained microbe base produces finished compost ready for garden use in as little as 30 days.

What Is the Reencle Microbe Base?
The Reencle microbe base — sometimes called the base culture — is a proprietary blend of thermophilic (heat-loving) microorganisms that comes pre-loaded inside your Reencle composter. These are living bacteria and fungi selected specifically for their ability to biologically break down a wide range of organic food waste, including fruit and vegetable scraps, cooked foods, grains, and even meat and dairy.
Think of it as a starter culture, similar in concept to the live cultures in yogurt or sourdough bread — except this colony's job is to continuously decompose food waste rather than ferment food. The microorganisms consume organic matter, generate heat through their metabolic activity, and produce a dark, earthy output that constitutes genuine compost.
This is not a chemical process. It is a biological one, driven entirely by living microbes.
Why the Microbe Base Is the Engine of the System
Without an active, healthy microbe base, the Reencle cannot function as a composter. Full stop.
Many people assume that the Reencle works by grinding or heating food waste — and while the unit does maintain a warm internal environment to support microbial activity, the actual breakdown is performed by the microorganisms themselves. The machine creates optimal conditions (temperature, aeration, and moisture control) for the microbe colony to thrive. The microbes do the work of decomposition.
This distinction matters because it explains what "real compost" actually means. Biological decomposition by microorganisms — the same process that occurs in a healthy backyard compost pile — creates humus: a structurally complex, nutrient-rich substance that improves soil health, water retention, and plant growth. A process that simply removes moisture through heat cannot replicate this. Dried food waste is still waste. Compost is biological transformation.
The microbe base is what makes Reencle a composter rather than a food dehydrator.
The Science Behind Thermophilic Composting Microbes
The microorganisms in the Reencle base culture are classified as thermophilic — meaning they thrive at elevated temperatures, typically between 50°C and 65°C (122–149°F). Two microbial groups are particularly central to the composting process inside Reencle:
Bacillus species are spore-forming bacteria that are exceptionally hardy and heat-tolerant. They produce enzymes — including proteases, lipases, and amylases — that break down proteins, fats, and starches respectively. This is why Reencle can process meat and dairy that traditional composting methods often cannot handle. Bacillus subtilis and related species are among the most well-studied composting organisms in soil microbiology literature.
Actinomycetes are filamentous bacteria that look and behave somewhat like fungi. They are responsible for the characteristic earthy, forest-soil smell of finished compost, produced through a compound called geosmin. Actinomycetes are particularly effective at breaking down tough, complex materials including cellulose and chitin. Their presence in the output is actually a reliable indicator of mature, biologically active compost.
Together, these organisms create a self-sustaining decomposition loop: as they break down food waste, they generate metabolic heat that keeps the internal temperature in the optimal range for their own activity — a positive feedback cycle that makes the system efficient and continuous.
How to Know If Your Microbe Base Is Healthy
A thriving microbe base gives clear signals. Here is what to look and smell for:
Active decomposition: Food scraps added to the unit should noticeably reduce in volume within 24 to 48 hours. If scraps are sitting unchanged for several days, decomposition may have slowed.
Earthy, soil-like smell: A healthy microbe base smells like rich forest soil or freshly turned earth — the signature scent of Actinomycetes at work. This is a positive sign. An ammonia smell suggests too much nitrogen-dense food was added at once. A sour or rotten smell may indicate the balance has been disrupted.
Appropriate warmth: The interior of the unit should feel noticeably warm when you open it. The microbes generate heat as a byproduct of their activity. A unit that feels room-temperature inside may have an underperforming colony.
Consistent output texture: Healthy compost output is dark, crumbly, and relatively uniform in texture. Chunky, wet, or stringy output can signal that decomposition is incomplete or the culture is struggling.
How to Maintain Your Microbe Base Day to Day
The microbe base requires consistent care — not intensive care. These habits will keep your colony performing at its best:
Feed steadily, not in large batches. Adding a large quantity of food waste all at once can overwhelm the microbe colony, slowing its activity and potentially causing odor. Add scraps in moderate amounts, giving the colony time to process each addition before loading more. The Reencle is designed for continuous daily input, not periodic large dumps.
Keep antibacterial agents away from the unit. This is critical. Antibacterial hand soaps, bleach-based cleaning products, and disinfectants contain compounds specifically designed to kill bacteria — including the beneficial ones in your microbe base. Always wash your hands with plain soap before handling the unit's interior, and never use antibacterial cleaning products inside the chamber.
Maintain stable ambient temperature. The thermophilic bacteria in the base culture prefer warmth. Placing the Reencle in a consistently warm location (not exposed to cold drafts or temperature extremes) helps the colony remain active and avoids the metabolic slowdown that cooler temperatures can cause.
Avoid excess high-acid foods. Citrus peels, vinegar-based foods, and highly acidic scraps can shift the pH inside the unit in ways that stress the microbe colony. These foods are fine in moderate quantities, but large amounts added all at once can temporarily inhibit microbial activity.
Periodically add fresh base culture. Even under ideal conditions, microbial populations naturally shift over time. Reencle recommends periodically replenishing the base culture — available as a refill — to maintain a robust and diverse population. This is similar to refreshing a sourdough starter to keep it at peak activity.
When to Add Fresh Microbe Base
There are specific situations where adding fresh microbe base is the right response:
Decomposition has slowed significantly. If food scraps are taking much longer than usual to break down and the other maintenance steps have not resolved it, the microbe population may have declined below its effective density. Fresh base culture reintroduces a concentrated population and restores performance.
After cleaning the interior of the unit. If you have had to clean the inside of the composting chamber — particularly if any cleaning agent (even mild soap) made contact with the substrate — the microbe population may have been reduced. Adding fresh base culture helps re-establish the colony.
After accidentally introducing antibacterial substances. If antibacterial soap, disinfectant, or similar agents entered the chamber, treat this as a reset situation. Remove as much of the substrate as possible, clean the chamber with plain water only, and restart with a full fresh application of base culture.
After extended dormancy. If the unit has been stored or unused for several weeks, the microbial colony may have declined. Restart with fresh base culture before resuming regular use.
As routine seasonal maintenance. Even when performance is normal, adding fresh base culture every few months is a sound preventive practice — particularly before periods of heavier use, such as the summer months when garden-to-kitchen cycles produce more food waste.
How the Microbe Base Differs from Heat-Only Approaches
This distinction is important for anyone comparing composting approaches.
Some food waste appliances on the market use high heat as their primary mechanism — temperatures that can reach 70°C to over 80°C for sustained periods. At these temperatures, the vast majority of microorganisms are killed. The output is a dried, reduced-mass material, but it is not compost in the biological sense. It has not been transformed by microbial activity. It is dehydrated food waste.
Reencle operates differently by design. The internal temperature supports microbial activity without killing the colony. The goal is not to remove moisture through heat — it is to maintain an environment where thermophilic bacteria can continuously perform biological decomposition. The result is a genuinely different output: real compost produced by a living, self-sustaining culture.
This is also why the Reencle system can keep functioning continuously rather than requiring full restart cycles after each batch. The living culture persists and builds over time when properly maintained, which is what makes 30-day turnaround possible for kitchen-to-garden use.
Frequently Asked Questions
How often do I need to add microbe base?
Under normal use with proper daily maintenance, most users add fresh microbe base every one to three months. The exact frequency depends on your usage intensity and how consistently you follow the maintenance guidelines above. If you add a wide variety of food scraps daily, your colony is actively working and may benefit from more frequent refreshing. If you add scraps less often, the colony may remain stable for longer. Pay attention to the performance signals described above — those are your best guide.
Can I make my own microbe base?
It is not recommended. The Reencle microbe base is a proprietary blend of specific thermophilic strains selected for their ability to work together effectively inside the unit's operating conditions. DIY alternatives — such as garden soil or backyard compost inoculants — contain different microbial communities, typically mesophilic organisms that are adapted to outdoor temperature ranges. These may not thrive or perform comparably under the Reencle's internal conditions. For consistent results, use Reencle's official base culture refill.
What kills the Reencle microbes?
The main threats to the microbe colony are: antibacterial soaps and chemical disinfectants (the most common cause of colony disruption), very high doses of high-acid foods like citrus or vinegar, sustained very low ambient temperatures that cause the colony to become dormant, and the introduction of substances like bleach or strong cleaners into the chamber. In all these cases, the solution is to assess the damage, remove any harmful substance if possible, and reintroduce fresh base culture to restore the colony.
How do I know if my microbe base is still alive?
The clearest real-world test is to add a small amount of fresh food waste and observe what happens over 24 to 48 hours. If it reduces in volume, the chamber feels warm inside, and the smell is earthy rather than sour or rotten, your colony is alive and active. If nothing changes after 48 hours — no volume reduction, no warmth, unusual odor — the colony has likely declined and it is time to add fresh base culture. You can also look for the presence of fine, white filamentous material in the substrate, which is a visible sign of Actinomycetes activity.
Is the microbe base safe for food scraps including meat?
Yes. The thermophilic bacteria in the Reencle base culture — particularly Bacillus species — produce lipase and protease enzymes specifically capable of breaking down fats and proteins. This means the Reencle can process meat, fish, and dairy that traditional backyard composting bins and many kitchen composters cannot handle safely. The high internal operating temperature also inhibits pathogen survival, making the process safe for these inputs when used as directed.
