Salinity as an Abiotic Stressor for Eliciting Bioactive Compounds in Marine Microalgae.

This study investigated the impact of culture medium salinity (5-50 PSU) on the growth and maximum photochemical yield of photosystem II (/) and the composition of carotenoids, fatty acids, and bioactive substances in three marine microalgae (, , and ). The microalgae were photoautotrophically cultured in discontinuous mode in a single stage (S1) and a two-stage culture with salt shock (S2). A growth model was developed to link biomass productivity with salinity for each species.

Bioactives Overproduction through Operational Strategies in the Ichthyotoxic Microalga Culture.

The red tide-forming microalga has been associated with massive events of fish deaths, both wild and cultured. Culture conditions are responsible for the synthesis or accumulation of some metabolites with different interesting bioactivities. LC269919 strain was grown in a 10 L bubble column photobioreactor artificially illuminated with multi-coloured LED lights.
