Abstract

Graphical abstract: Highlights: Amphidinium carterae is a good candidate to be exploited in larger scale. A short light-path improves the main biotic parameters in A . carterae cultures. Several high value metabolites can be extracted from A . carterae biomass. Natural flocculation and self cleaning properties were found in A . carterae cultures. Abstract: The aim of this work was to study the culture performance of a dinoflagellate in a commercial photobioreactor. The results obtained during this long-term experiment allow to confirm that Amphidinium carterae is a promising dinoflagellate that can be exploited successfully in closed systems, in semi-continuous mode in indoor and outdoor environments. The average results in an indoor 5 cm light-path 320 L photobioreactor were, in terms of specific growth rate (0.29 d −1 ), duplication time (3.1 d −1 ) and dry biomass productivity (78 mg L −1 d −1 ). Specific compounds production was found including ω 3 and ω 6 fatty acids and, pigments (Peridinin, β -carotene). These promising results, besides unique characteristics found during the exploitation period such as resistance to mechanical stress, self-control of contaminant organisms, and quick cells aggregation when the culture is not in turbulence conditions, makes A . carterae one of the new target species suitable for commercially exploitation on an industrial scale.
