Due to an increasing focus on heathy diets and low-fat products, huge amounts of animal fat by-products are processed annually by fat processors and renderers. Most of the produced fat products are used for energy consumption. To add value to these products, the LipoFungi project will develop innovative technology for upgrading Norwegian animal slaughter fat by-products by fungal fermentation processes. It will develop technology for conversion of animal fat materials into high-value lipids and carotenoids-rich fungal biomass for animal feed.
In a pilot study, we have shown that oleaginous fungi from the phylum Zygomycetes can convert saturated fatty acids from animal fat by-products containing triacylglycerols (SAT-TAGs), into polyunsaturated fatty acids containing triacylglycerols (PUFA-TAGs). Large parts of the produced fat by-products produced in Norway and Europe today are either edible fat, which fits for human consumption or so-called Category 3 fat, which is suitable for animal feed. Therefore, depending on the type of fat by-product, high-value fatty acids produced from Category 3 or edible fat rest materials can be used for either feed or for human consumption. The project addresses the most central biological and technological research challenges for developing a sustainable process for lipid upgrading from animal rest fat. It suggests research for developing fermentation technology for submerged and solid-state fermentation, process optimization and upscaling. The project will evaluate the final product and perform a preliminary economic evaluation of the process. The project will make use of the NordBioLab infrastructure facilities at NMBU and constitutes a multi-disciplinary and cross-institutional collaboration involving all competencies required for such a complex goal.
