Domsjö Fabriker invests in two multi-bioreactor systems

Salmonaid is a new Swedish project initiated by RISE Bioscience and Materials, Processum, SLU and Domsjö Fabriker and financed by Vinnova.

With microorganisms cultivated on side streams from the forest industry, the project aims to optimize the process for production of microbe-based protein with higher protein content, as well as try out oil production, to use as salmon feed. The raw material will then be evaluated as substitute for primarily soy-based but also fish-based feedstock used in today's fish feed.

"Processum has recently invested in two multi bioreactor systems in which we with Spent sulphite liquor from Domsjö Fabriker as raw material and with the aid of microorganisms in this project will produce protein and oil for fish feed", says Björn Alriksson, Biotechnology Manager, Processum.

"The cultivation trials will be performed under different conditions in order to optimize the process for production of a high-quality protein product. When we have found the prerequisites for a high quality product we will successively produce increasing amounts in our bioreactors. At the end of the project period our aim is to be able to produce high quality single cell protein that works well in fish feed and which in turn gives good results in feeding of fish."

Salmonaid is mainly financed by Vinnova, Sweden's innovation agency, as well as by Domsjö Fabriker.
