Cultivating
Progress
VISION
Our vision is to be a leading enabler
of the biosolutions urgently needed
to restore planetary health
STATUS QUO
Too many fermentation businesses fail
Start your journey - choose a track
With FlexCell® technology, you can rapidly validate your microbial innovations, reduce development costs, and pave the way for safe, efficient deployment at industrial scale.
If you need robust strain-to-starter-culture development, or quality certified inoculum for biomanufacturing, this is for you.
DIFFRENCE
DIRINOC™
Our Direct Inoculum technology radically
improves profitability, flexibility and efficiency.
With our seed train services we enable companies to obtain a readily available concentrated
starter culture that seeds the commercial scale bioreactor and yields considerable savings.
CORPORATES AND CDMO’S
ORIP
Organism Robustness Induction Program
This is the development program, starting with the transfer of the strain,
and ending with an orderable, stable starter culture.
-
Metabolic pathway mapping using a proprietary AI model suggesting best strategies for production of a stable, storable, concentrated starter culture
-
Wet trials in the lab for optimal media formulation, propagation conditions, concentration- and packaging strategy
-
Validation run using our FlexCell® production platform.
Quality certification and packaging logistics determined. -
Order your starter culture whenever you need it!
CORPORATES AND CDMO’S
DIRINOC™
DIRINOC™ is a ready-to-use starter culture, developed from the client’s own strain after going through the ORIP program.
It’s available on demand and ready for direct use in fermentation.

CORPORATES AND CMO’S
We are agnostic to which microbe...
We can handle almost any species, wild type or genetically modified organisms, unlocking microbial biodiversity in biomanufacturing.
FlexCell® —
the breakthrough tech that makes progress possible
STARTUPS & SCALE-UPS
Our proprietary FlexCell® technology gives food and biotech companies of any size a faster and dramatically more affordable way to validate the commercial potential of their microorganism.
STARTUPS & SCALE-UPS
Step 1 / Customize your FlexVessel bioreactor
-
Works for a wide array of microorganisms, including yeast, filamentous fungi, bacteria and algae
No risk of cross-contamination
-
Unlimited and immediate configurations for ports and probes, available across bioreactors ranging from 10 L to 400 L, ensuring adaptability for any food- or biotech-grade application
-
No need for time-consuming CIP (Clean-in-Place) and SIP (Sterilize-in-Place). Run unlimited fermentations side-by-side
-
Compatible with stock or proprietary propagation media
STARTUPS & SCALE-UPS
Step 2 / Define your process parameters and data collection
-
— Substrate
— Temperature
— Oxygen availability
— Substrate feed
— pH, and more
-
— Density & pH
— Optical density
— Dissolved oxygen
— Gas mass-flow (CO2 etc.)
-
— Fingerprinting
— Titer
— Target molecule quantification
— qPCR
— Viability
— Productivity
— Biomass Yield
STARTUPS & SCALE-UPS
Step 3 / Select your quality parameters, downstream processing and product harvest
-
We collaborate with you to establish the most relevant quality parameters, customizing them to fit your process
-
We offer non-intrusive biomass concentration and harvest solutions
-
Our capabilities ensure you meet all relevant organic, food safety, GMO and ISO standards, certifications and requirements
-
If needed, strains can be cryogenically stored, ready for deployment at short notice
Your needs, Our priority
Tell us what you’re looking for — we’ll do the rest.
Fast, simple, and effective.
First there was a company that made yeast...
Swan Neck Bio™ is a spin-out from White Labs - a global leader in fermentation since 1995.
White Labs’ pioneering FlexCell technology revolutionized the brewing industry by enabling yeast to be grown and packaged in the same vessel.
At Swan Neck Bio, we’re applying this single-use bioreactor technology to produce ready-to-use seed cultures of any microbe for biomanufacturing applications around the world.
Core Team
Headquartered in Copenhagen and with supporting lab- and production capabilities in San Diego, CA, and Asheville, NC our team of microbiologists and fermentation specialists is on a mission to accelerate success for biomanufacturing companies.
