carbohydrates storage products α-(1-4)-glucane, β-(1-3)-glucane fructane glycerol up to 50% of dry weight proteins proteins with all amino acids partly soluble and partly bounded as particulate up to 50% of dry weight 4 valuable compounds carotenoids, i.e. astaxanthin, fucoxanthin, lutein phytosterols (C28, C29), all vitamins and antioxidants anti-fungal, -viral and -microbial from 1 – 5% each of dry weight Analysis of the nutritional and technological Contact characteristics of the resulting fractions In collaboration with the joint project partners, an analysis of the nutritional and technological characteristics of the extracts obtained is simultaneously being carried out; for example, the health-promoting antioxidative and antiproliferative properties and the bioavailability of the ingredients are being investi- gated. The data obtained will serve as a basis for statutory ap- proval of different microalgae species as well as their extracts for use in human food products. Outlook Upon completion of the project, the goal is to have a method matrix for processing algal biomass that can be transferred to the biomass of different algae species that differ in terms of material composition and target fractions. This would be a huge step closer to achieving the objective of using microal- gae holistically for nutrition as an important component in the bioeconomy. triacylglycerides storage lipids triacylglycerides with mainly C16 to C18 fatty acids up to 70% of dry weight membrane lipids glyco- and phospholipids up to 40% of fatty acids are poly- unsaturated, i.e. eicosapentaenoic acid (EPA) up to 7% EPA of dry weight Dr. rer. nat.

We would like to thank the Baden-Württemberg Stiftung and the Ministry of Sci- ence, Research and the Arts of the State of Baden-Württemberg for funding the project “Microalgae – Integrated Use for Food and Feed. Partial Project: Development of Cell Disruption and Extraction Processes for the Cascade Utilization of Microalgal Biomass” (Mikroalgen – Integrierte Nutzung für die Ernährung.
