Fermenting change

The obstacles to success in the biotechnology business are high. Kerry is the collaborator you need to clear the path.

Six of the world’s top 10 blockbuster biotech drugs, and around a quarter of all biotech drugs on the market, use Kerry’s Sheffield brand components in their media.

We are the only manufacturers of both peptones and yeast extracts. We collaborate with our customers from the initial feasibility studies through to the final testing and implementation stage.

Plus, our global network of laboratories, and regulatory compliance experts enable us to meet Pharma requirements globally.

Kerry’s product portfolio has grown to encompass plant based hydrolysates to chemically defined medium.

This diversity ensures that there is a medium to suit your application, whether your goal is disease treatment, disease prevention, novel fermentation derivatives, or media innovation.
