Scaling-Up and Semi-Continuous Cultivation of Locally Isolated Marine Microalgae Tetraselmis striata in the Subtropical Island of Gran Canaria (Canary Islands, Spain)

The goal of this study was to determine the feasibility large-scale cultivation locally isolated Tetraselmis striata in different open ponds Gran Canaria. biomass productivities were 24.66 ± 0.53 kgDW 32 days (28.9 t/ha/year) for 8000 L indoors, 42.32 0.81 43 (38.8 an pond outdoors, and 54.9 0.58 28 (19.6 a 45,000 outdoors. photosynthetic efficiencies 1.45 0.03% 1.95 0.04% 1.10 0.01% selected strain fast-growing (µ = 0.21 day?1) could be rapidly scaled up L; it formed healthy cultures that maintained high activity during long-term provided stable productivities, able grow on urea, which acted as cheap effective grazer control. obtained is good source proteins has FA profile with content some nutritionally important fatty acids: oleic, ?-linolenic (ALA) EPA. ash (>35%) can reduced by implementation additional washing steps after centrifugation culture.
