Longevity Active Ingredients: How a New Process Is Transforming Active Ingredient Production

Under the banner of “longevity,” a market with double-digit growth has emerged for active ingredients that target healthy aging and cellular function. One of the most prominent examples is NMN (nicotinamide mononucleotide), a precursor to the coenzyme NAD⁺, which drives energy production in every cell.

NMN illustrates why the choice of process determines purity, cost, and marketability. Yet perhaps the most elegant approach still utilizes nature’s tools: enzymatic cascade biocatalysis. The process does not require living cells, yet it still harnesses the elegance of biological processes. For process engineering, this is more than just a laboratory curiosity—it is a reaction concept with tangible advantages in terms of purity, process control, and scalability.

The principle: one reactor, multiple enzymes

Traditional chemical syntheses build up a complex molecule step by step—each step with its own reaction, its own purification, and its own solvent. Fermentation takes the opposite approach: it lets microorganisms do all the work, but in return accepts that the cell also produces countless byproducts that must later be laboriously separated.

Cascade biocatalysis lies somewhere in between. It uses isolated enzymes—that is, the biological catalysts that control every single metabolic reaction in nature—but deploys them specifically outside the cell. Multiple enzymes work sequentially in a single reaction vessel, like on a molecular assembly line: the product of the first enzyme serves as the starting material for the second, and so on, until the target molecule is formed. In technical jargon, this is called “one-pot synthesis” because the intermediate products do not need to be isolated.

For NMN, this allows the finished molecule to be synthesized from relatively inexpensive starting materials in just a few coupled steps—without aggressive reagents and without the endotoxin issues that complicate subsequent purification in bacterial fermentations.

The advantages speak for themselves: The reactions proceed under mild conditions—moderate temperatures, an aqueous environment—which reduces the need for strict humidity control, as is required in many chemical synthesis routes for nucleotide derivatives. Enzymes act with high specificity, meaning they produce virtually no unwanted byproducts. The result is high product purity with a comparatively simple purification process.

Recent research findings demonstrate how far this approach has come. Using an optimized enzyme derived from a yeast species and a system for regenerating the expensive cofactor ATP, 100 g/L of nicotinamide riboside as a starting material can be almost completely converted into NMN within a few hours—with yields in the range of around 80 % and above.

The Toolkit: Enzyme Engineering

The key to these advances is what is known as enzyme engineering—the targeted modification of enzymes so that they work faster, are more stable, and perform more reliably under industrial conditions. Enzymes are essentially complexly folded protein molecules. By replacing individual building blocks at the right locations, their activity can be dramatically increased. 
In one documented case, a single, targeted change increased the activity of a key enzyme by several hundred percent.

Three levers are particularly relevant here. First, the optimization of rate-limiting enzymes—that is, those steps that, like a bottleneck, dictate the pace of the entire cascade. Second, cofactor regeneration: Many enzymes require expensive cofactors such as ATP, which cannot be supplied in stoichiometric quantities. An integrated regeneration system recycles these cofactors, thereby significantly reducing costs. Third, immobilization—that is, attaching the enzymes to carrier materials so that they can be recovered after the reaction and reused multiple times.

The Areas Still Under Development

As compelling as the concept is—the challenges lie in areas where process engineering has traditionally been strong. Providing the enzymes in sufficient quantities and consistent quality is a production step in its own right, which in turn requires fermentation and purification. The long-term stability of the enzymes under real process conditions is critical to economic viability. And even though purification is simpler than fermentation, downstream processing—separation, concentration, and drying into a storable powder—remains a key cost factor.

This is where biocatalysis intersects with traditional plant engineering. Reactor design for optimal mixing and temperature control of the enzyme cascade; membrane and filtration technology for separating the biocatalysts; continuous rather than batch-based process control to increase efficiency; and finally, drying and formulation into the finished active ingredient powder—these are the tasks on which success at the production scale depends.

A Reaction Concept with a Future

Cascade biocatalysis is not an exotic special case, but rather part of a broader trend toward biotechnological production processes that are increasingly supported by data analysis and machine learning in enzyme selection and process optimization. It is attractive to manufacturers of longevity active ingredients because it delivers high purity without the drawbacks of traditional chemistry or whole-cell fermentation. It is of interest to the machinery and plant engineering sector because, at critical points, it requires precisely the process engineering expertise that forms the backbone of the industry.
