Growth performance, biochemical composition and sedimentation velocity of Tetraselmis sp. CTP4 under different salinities using low-cost lab- and pilot-scale systems.

ABSTRACT: Biomass harvesting is one of the most expensive steps of the whole microalgal production pipeline. Therefore, the present work aimed to understand the effect of salinity on the growth performance, biochemical composition and sedimentation velocity of Tetraselmis sp. CTP4, in order to establish an effective low-cost pilot-scale harvesting system for this strain. At lab scale, similar growth performance was obtained in cultures grown at salinities of 5, 10 and 20 g L^-1 NaCl. In addition, identical settling velocities (2.4-3.6 cm h^-1) were observed on all salinities under study, regardless of the growth stage. However, higher salinities (20 g L^-1) promoted a significant increase in lipid contents in this strain compared to when this microalga was cultiv
