Fermentation technology for sustainable chemicals and food ingredients
Fermentation has been used for centuries to make food products more tasteful and longer-lasting. Today it is also used as a sustainable alternative for the production of specific chemicals and food ingredients which are still being made with synthetic, fossil-based processes. Wageningen Food & Biobased Research has a strong track record on fermentation technology for food products and chemicals. With our unique lab-to-pilot approach we offer companies novel opportunities to find the most cost-effective route to a given fermentation process.
In the dedicated fermenter labs of Wageningen University & Research, we can scale up fermentation processes to 2, 100 and even 1000 litres. We use CRISPR/CAS and mathematical modelling to improve our fermentation processes, and work with a variety of micro-organisms which range from yeasts and fungi to anaerobic bacteria and algae.
Our strong track record in anaerobic fermentation routes and the use of cost-effective side streams is key to increasing product yields and volumetric productivity, reducing the costs of raw materials and energy input. As such, we are able to design fermentation processes that can compete with petrochemical processes even when oil prices are modest, as well as processes that are uniquely suited to developing new, functional and healthy food ingredients.

Industrial interest
“We see a strong industrial interest in fermentation for the production of chemical building blocks and food ingredients,” says Jeroen Hugenholtz, senior fermentation expert at Wageningen Food & Biobased Research. “To begin with, fermentation is affordable because we reuse waste streams, for example from the sugar beet industry. In addition, it is energy efficient as the microorganisms do their work at low temperatures. And because we are understanding the microorganisms better each day, fermentation is becoming an attractive and affordable solution for more and more applications.”
An example is the work we have done for Total and Corbion on optimising the production of polylactic acid. PLA is a fully bio-based plastic with excellent functional properties. Thanks to our contribution, PLA can now be produced in an affordable way, making it possible for the PLA market to expand.
