Algae are bioresources of antioxidants, PUFAs, food, and biofuels. Currently, commercial microalgal production is limited to model mesophilic organisms with optimal growth temperatures around 25 ºC. Their production at higher latitudes will have to be restricted to summer periods or require large amounts of energy to warm up the culture media. Ther...

Project
The main objectives of the ALGAESOLUTIONS project are: a) to provide innovative solutions to common problems of algal producers by increasing the productivity, quality and market value of the biomass produced and b) develop five products with high commercial value: i) AllPhaeo+, a microalgal product enriched in fucoxanthin and polyunsaturated fatty acids (PUFA) and ii) AllNanno+, a microalgal product enriched in the PUFA eicosapentaenoic acid (EPA) aiming for the aquaculture feed sector; iii) AtlanticNori+, a macroalgal product enriched in phycobiliproteins and PUFA and iv) ConchoNori+, a macroalgal product enriched in mycosporine-like amino acids and phycobiliproteins, using the Porphyra microscopic stage with strong potential for the food market as well as application in the cosmetic industry; and v) CleanCulture, a kit for early detection of algal contaminants for algal producing companies. To attain these two objectives, ALGAESOLUTIONS will develop and provide the entrepreneurial partners of the project with two innovative technological tools: i) LEDsScale, a high-throughput algal scale-up system, which will decrease time and labor by 25% compared to traditional approaches; and ii) LEDsInduce, a high-value target metabolite induction system to be used as a finishing step during algal cultivation to increase pigment, PUFA or protein content in algal biomass by up to three-fold. These innovative products and solutions will have a high economic value, as they will increase revenue and decrease costs and risks inherent in industrial algal production. ALGAESOLUTIONS is the result of a pre-existing consortium composed of the collaborative laboratory GreenCoLab, University of Algarve, and two algal producers, ALGAplus and Allmicroalgae. In sum, ALGAESOLUTIONS will provide innovative solutions to current production constraints, as well as novel premium products with significantly higher market value.
Project
Valorisation of greenhouse effluents with microalgae: Sustainable aquafeeds and biostimulants from drain water. Every drop counts in soilless crop production as the intensive use of fresh water and the release of nutrient-rich effluents (drainage water) negatively impacts the environment. AlgaCycle will re-use these drain waters to produce microalgae. The resulting microalgal biomass will be fractionated into water extracts and residual debris. These fractions will be used for biostimulants for plants or feeds in aquaculture.
Project
1.) Improvement of cultivation strategies of microalgae in cold climates. 2.) Identification of biotechnological promising cold-adapted strains. 3.) Improvement of artificial lighting for microalgal cultivation.
