Enzyme Catalysis Process Development
Scalable Photoenzymatic Process Development
We develop light-driven enzymatic processes that hold stereoselectivity from screening scale toward pilot-ready, transferable manufacturing.
What Photoenzymatic Process Development Is
Photoenzymatic process development couples light-driven energy input to enzymatic catalysis. Photons activate or regenerate the cofactor or reagent that feeds the reaction, while the enzyme supplies the stereoselectivity and substrate specificity that small-molecule chemistry often struggles to match. The result is a route to chiral molecules under mild, light-driven conditions rather than the demanding conditions of traditional asymmetric synthesis.
The engineering problem is not the chemistry alone. Light-driven biocatalytic processes are notoriously hampered by poor penetration of light into turbid reaction media, so the practical challenge is delivering uniform, sufficient photons to every catalytic site while keeping the enzyme stable and active. Scalable designs commonly use internally or wirelessly powered light sources, such as LEDs, and intensified reactor formats to overcome those penetration limits.
This service is built for process chemistry groups in pharma and CDMO organizations who have a photoenzymatic route at bench scale and need it defined, characterized, and made reproducible before it moves toward pilot or manufacturing scale. Development then optimizes parameters such as light intensity and wavelength, catalyst loading, cofactor supply, temperature, and residence time so that the process behaves the same way when it is transferred.
Light In, Selectivity Out
The enzyme sets the stereochemical outcome; light supplies the energy that drives or regenerates the reactive species. Development work has to serve both halves of that system at once.
- Enzyme selection and engineering for photo-driven or light-coupled reactivity
- Cofactor and regeneration system design, including NAD(P)H recycling
- Reaction medium and substrate loading tuned for light penetration
Photon Delivery at Scale
Light penetration into turbid or absorbing media is the constraint that most often blocks scale-up. Reactor and illumination design is therefore treated as a core development activity, not an accessory.
- Light source selection and photon delivery design, including LED-based formats
- Internally or wirelessly powered illumination options for intensified reactors
- Mixing and format choices that keep illumination uniform across the vessel
A Transferable Process
The deliverable is a defined process with a characterized design space, an analytical control package, and documentation that a receiving team can execute reproducibly.
- Process parameter screening and design space definition
- Analytical method development and impurity profiling
- Scale-up, technology transfer, and full documentation

How an Engagement Runs
Projects move from feasibility through definition to transfer. Each stage produces something the next stage depends on, so the sequence is deliberate rather than a menu of independent experiments.
Feasibility and Enzyme Selection
We review the target transformation and the available enzyme or photobiocatalyst system, assess whether photo-driven or light-coupled reactivity is achievable, and define the analytical methods needed to measure progress.
Cofactor and Light System Design
The cofactor or regeneration strategy is fixed, and the illumination concept is chosen: light source type, wavelength, and whether internal or wirelessly powered LEDs suit the reaction medium and vessel format.
Parameter Screening and Design Space
Light intensity, wavelength, catalyst loading, cofactor supply, temperature, pH, substrate loading, and residence time are screened to map the operating window and identify the parameters that most influence selectivity and conversion.
Stability and Safety Characterization
Photostability and enzyme stability data are generated under representative conditions, and scale-up risk is mapped for the light-driven step so that safety and process boundaries are understood before larger runs.
What We Customize
Every photoenzymatic system has its own balance between enzyme behavior, cofactor economics, and light delivery. Scope is set case by case after consultation, and the parameters below describe what can be adjusted rather than a fixed bundle.
Enzyme and Cofactor Strategy
Enzyme selection or engineering for light-coupled reactivity is paired with a cofactor supply and regeneration design suited to the reaction, such as NAD(P)H recycling where the system requires it.
- Enzyme sourcing and engineering options scoped to the target transformation
- Cofactor regeneration design matched to reaction stoichiometry
- Activity and stability benchmarking under light-driven conditions
Light Delivery and Reactor Format
Illumination is engineered for the medium rather than assumed. Options include externally mounted sources, internally illuminated formats, and wirelessly powered LEDs for intensified reactors where light penetration limits performance.
- Wavelength and intensity selection for the enzyme and cofactor system
- Reactor geometry and mixing chosen to keep illumination uniform
- Intensified formats considered where turbidity limits photon delivery
Analytical and Impurity Control
Analytical methods are developed alongside the process so that stereochemical purity, conversion, and impurity formation can be tracked reproducibly from screening through scale-up.
- Method development for chiral purity and conversion
- Impurity identification and profiling across the light-driven step
- Documentation of methods for the receiving team

Why Teams Choose This Approach
Photoenzymatic scale-up fails for predictable reasons: light that does not reach the catalyst, enzymes that lose activity under illumination, and parameters that were never mapped into a design space. Development work is organized around those failure modes.
The service also keeps the scientific and the practical in the same conversation. Process chemistry groups get a defined operating window and a documentation set, while the underlying enzyme and cofactor behavior is characterized well enough to support decisions about scale.
Light Penetration Treated as the Core Problem
Because poor light penetration into turbid media is the recognized constraint on light-driven biocatalysis, illumination and reactor design are developed as primary process variables rather than fixed equipment assumptions.
- LED-based and internally illuminated formats evaluated for the medium
- Wirelessly powered illumination considered for intensified reactors
- Mixing and geometry assessed for uniform photon delivery
Enzyme and Cofactor Behavior Characterized
Enzyme stability under light-driven conditions and cofactor regeneration are studied together, since selectivity depends on the enzyme while sustained conversion depends on the regeneration system.
- Photostability and activity data generated under representative conditions
- Regeneration strategy matched to reaction demand
- Selectivity tracked alongside conversion throughout development
Documentation Built for Transfer
Process description, analytical methods, parameter ranges, and scale-up findings are compiled so a receiving team can execute the process reproducibly.
- Process description and operating parameter documentation
- Analytical and impurity methods documented for handover
- Technology transfer support for the receiving site

Working With Process Chemistry Teams
Engagements are usually initiated by process chemistry or chemical development groups that already have a photoenzymatic route at bench scale and need it defined before committing to larger equipment or a transfer.
The work is structured to fit alongside internal programs: findings are shared at milestones, and the documentation is written so it can be used directly in internal reviews and transfer planning.

Starting a Project
A project typically begins with a technical discussion covering the target transformation, the current route, available enzyme or photobiocatalyst systems, and the scale the process needs to reach. From there, scope, deliverables, and analytical requirements are agreed in the statement of work.
If the route is still at an early stage, a feasibility assessment is often the practical first step, since it establishes whether the photoenzymatic approach can deliver the selectivity and conversion the program requires before larger development commitments are made.
FAQ
How is photoenzymatic process development different from classical chemical process development?
Classical chemical process development focuses on synthetic route selection, thermal safety, and isolation of small molecules. A photoenzymatic process adds two coupled systems: an enzyme that sets stereoselectivity and a light-driven energy input that activates or regenerates the cofactor or reagent. Development therefore centers on illumination, cofactor supply, enzyme stability under light, and the parameters that govern both, rather than on route scouting or crystallization behavior.
Why is light delivery such a central issue in scale-up?
Light-driven biocatalytic processes are widely reported to be hampered by poor penetration of light into turbid reaction media. As vessels get larger and media become more absorbing, photons may not reach the catalytic sites uniformly, which affects conversion and reproducibility. Scalable designs commonly address this with internally or wirelessly powered light sources such as LEDs and with intensified reactor formats, and illumination design is treated as a core development activity in our projects.
Do you work with isolated enzymes or whole cells?
The focus of this service is photoenzymatic process development using enzyme or photobiocatalyst systems in reaction media, where light input is the primary energy driver and the enzyme provides selectivity. If your program involves a whole-cell format, that is discussed during the technical consultation so the scope reflects the actual system rather than a standard template.
What stability information will we receive?
Photostability and enzyme stability are assessed under conditions representative of the intended process, and the results are reported as part of the data package. Enzyme stability is a recognized challenge for photo- and electro-enzymatic routes, so these data are generated to inform operating ranges and to support decisions about scale, rather than presented as a guarantee of performance at any particular scale.
How is the analytical and impurity control package defined?
Analytical methods for chiral purity, conversion, and impurity profiling are developed alongside the process and documented for handover. The depth of the package, including which impurities are tracked and how methods are validated, is agreed in the statement of work based on your program's requirements and the stage of development.
What does technology transfer include?
The transfer package typically includes a process description, analytical methods, operating parameters and ranges, and the findings from demonstration runs at increasing scale. Contents and depth are scoped per project so the receiving team has the documentation needed to execute the process reproducibly at the agreed scale.
