Protinext is a contract development and manufacturing organisation (CDMO) for microbial fermentation. We take your process from lab flask to commercial scale, and produce it for you once it gets there.

We work with bacteria, yeasts, fungi and microalgae, including heterotrophic algae such as Chlorella. Whatever your organism, we adapt media, process conditions and downstream steps to fit it, rather than forcing it into a standard recipe.

Our services cover the full route: process development, tech transfer, scale-up and contract manufacturing, followed by downstream processing into a ready-to-use ingredient. Our facilities in the Netherlands include a fully equipped laboratory, pilot reactors and 50,000L of production fermenter capacity.

Our customers develop ingredients for food, feed, cosmetics, pharma and specialty chemicals. They come to us because building a fermentation plant takes years and millions; working with Protinext takes one conversation.

• Process development: strain screening, media optimisation and process design at lab scale.
• Tech transfer: we review your process data, close the gaps and translate it to our equipment.
• Scale-up: stepwise from bench to pilot to production, with clear go/no-go criteria at every step.
• Contract manufacturing: reliable commercial batches, with full batch records and release testing.
• Downstream processing: harvest, washing, concentration and drying into a ready-to-use ingredient.

We are excited to partner with you to create innovative and sustainable solutions using microalgae. Contact us today to learn more about our products, services and how we can help you stay ahead in your competitive environment.

• Fully equipped laboratory.
• Lab, pilot and production scale fermenters: from 2L to 6000L.
• Downstream equipment: separation, washing, drying.

• Building your own fermentation plant takes years and millions. Working with Protinext starts with one conversation.
