Single cell oil PUFA production by food rest materials

Our innovative idea is to optimise fungal fermentation of Norwegian rest materials, such as potato peel, chicken rest material, eggshell rest material and fish rest material, for an environmentally friendly production of single cell oil rich in high-value PUFA, such as GLA, EPA and ARA.

In order to utilize fungal production of rest materials from food industry in Norway, there is a need of research to

1. Establish processes that transform the existing rest materials into suitable fermentation media

2. Screen fungal strains in order to identify strains that optimize PUFA production in industrial processes

3. Optimize lipid extraction and purification process on both lab and industrial scale

This requires extensive screening studies involving hundreds of fungal strains and high numbers of test fermentations, and, not least, analytical tools for monitoring the production of PUFAs. Recently, we together with several partners developed a fully automated system by which several hundred fermentations (up to 1584 fermentations) can be performed in parallel and by which PUFA production can be monitored by FTIR spectroscopy in each single fermentation. Thus, by this system large numbers of conditions can be screened allowing an effective optimization of single cell oil processes. This fully automated system for monitoring PUFA in high-throughput cultivation is unique world-wide and provides a clear advantage for the Norwegian industry in the development of such biotechnological industrial processes.
