2015|16 Annual Report Fraunhofer IGB - CASCADE USE OF MICROALGAE BIOMASS

109 Dr. rer. nat. Ulrike Schmid-Staiger Phone +49 711 970-4111 ulrike.schmid-staiger@ igb.fraunhofer.de Felix Derwenskus M. Eng. Phone +49 711 970-4074 felix.derwenskus@igb.fraunhofer.de Contact Outlook The aim at the end of the project is to have a matrix of methods available for the processing of algae biomass that can be transferred to biomass of various algae species, with a different material composition in each case and with different target fractions. This would contribute a big step towards using microalgae holistically for nutritional purposes as well as an important step towards a biobased economy. 1 Pressurized Liquid Extraction unit in laboratory scale (Dionex, ASE 350). 2 Utilizable algae ingredients with increasing polarity and the corresponding solvents used for extraction. 3 Extracts of microalgae biomass (from left to right): N. oceanica, P. tricornutum und C. vulgaris. The different color is caused by strain-specific carotenoids. 4 Fatty acid profile and protein content of algae biomass. Funding The project is conducted at the Institute of Interfacial Process Engineering and Plasma Technology IGVP, Fraunhofer IGB’s partner institute at the University of Stuttgart. 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 Microalgae Biomass” (Mikroalgen – Integrierte Nutzung für die Ernährung. Teilprojekt Entwicklung von Zellaufschluss- und Extraktionsver- fahren zur Kaskadennutzung von Mikroalgenbiomasse) in the Baden-Württemberg Bioeconomy research program, reference no. 7533-10-5-93.
