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. The microbes replicate themselves continuously as they feed — you don't replace them on a schedule. No subscription, no pods, no routine refills. Keep the colony healthy by feeding it steadily and keeping antibacterial agents away from it. If your compost ever gets fully liquified (rare, and different from the more common wet/clumpy compost, which recovers on its own — see below), a fresh ReencleMicrobe (Compost Starter) restores it. 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.

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.
You don't need to add fresh base culture on a schedule. Under normal conditions, the microbes reproduce continuously as they feed — there's no subscription, no pods, and no routine refill required to keep the system running. What is on a schedule is emptying finished compost from the unit — most households empty every 1–3 months — which is a separate task from replacing the culture itself.
When to Add Fresh Microbe Base
Under normal use, you should never need to add fresh microbe base — the colony sustains and replicates itself as long as you keep feeding it and keep antibacterial agents out of the chamber. There is exactly one situation where a fresh ReencleMicrobe (Compost Starter) becomes necessary: full liquefaction.
Wet or clumped is not the same as dead. If your compost looks slightly clumped, wet, or soggy, that's a common, recoverable condition — not a sign the colony has died. Depending on severity, it typically resolves on its own: slightly clumped recovers in about 5–7 days, wet-and-clumping-but-still-soil-like in about 1–2 weeks, and severely wet with liquid pooling in 2+ weeks with active management.
How to recover a wet colony: If material is above the MIN fill line, remove the excess. Blot surface moisture with a paper towel, repeating as needed. Stop feeding the unit until moisture improves. Run Dry Mode for 24 hours if your unit has it. Then reintroduce food gradually — starting around 300g, then 500g, working back up to your normal daily amount (700g/day for Prime, 1kg/day for Gravity/Gravity Pro).
The one exception — full liquefaction. If the culture has fully liquified rather than just clumped or pooled, it won't recover with the steps above. This is the only case where you replace the microbe base with a fresh ReencleMicrobe (Compost Starter) — a recovery step, not routine maintenance.
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, you don't add fresh microbe base on any schedule — the colony replicates itself as it feeds, so there's no subscription, no pods, and no routine refill to plan around. The only time you need a fresh ReencleMicrobe (Compost Starter) is to recover from full liquefaction, which is uncommon and different from the more usual wet or clumpy compost (which recovers on its own — see above). What is on a schedule is emptying finished compost from the unit, which most households do every 1–3 months.
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 added all at once, sustained very low ambient temperatures that cause the colony to become dormant, and bleach or strong cleaners entering the chamber. In most cases the colony recovers on its own once the stressor is removed — stop feeding, let conditions stabilize (Dry Mode helps if things got wet), then reintroduce food gradually. A fresh ReencleMicrobe (Compost Starter) is only necessary if the culture fully liquifies and doesn't respond to the recovery steps above.
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 — try the recovery steps above (reduce feeding, improve moisture with Dry Mode, then reintroduce food gradually) before assuming the colony needs replacing. A fresh ReencleMicrobe (Compost Starter) is only needed if the material has fully liquified. 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.
