The aim of this project is to refine and scale up production of the NOVALGAE feed product, which is based on a marine microalgae, Tetraselmis sp., grown using a new heterotrophic fermentation process.

Marine microalgae are rich in proteins, lipids, omega fatty acids, vitamins and antioxidants. They form the basis of the marine food chain and are valuable feed to a range of aquaculture species. Traditionally microalgae are cultivated in photobioreactors. Its production is limited by light penetration and climate variation.
In this feasibility study, we have demonstrated that several marine microalgae could be cultivated heterotrophically in the lab. After medium screening and process optimisation, a marine microalgae strain was selected to grow in 5L stirred tank fermenters. Produced biomass was harvested and dried. Production of a high-value compound, Eicosapentaenoic Acid (EPA), was also detected. In conclusion, a novel and effective production method of an important aquaculture feed was demonstrated at the lab scale, paving its way to scale up, and eventually, commercialisation.
