Production characteristics of Phaeodactylum tricornutum Bohlin grown on medium with artificial sea water

Abstract

The growth of marine diatoms Phaeodactylum tricornutum was investigated on a medium with artificial sea water under artificial and natural light. The maximum specific growth rate was 0.7 day^–1, the productivity was 0.8 g/L day, and the maximum biomass was 3.86 g/L under artificial light in laboratory conditions. In the conditions of Crimea, the maximum productivity of P. tricornutum amounted to 6 g/m² day under natural light in an outdoor photobioreactor (pool). The results of cultivation of P. tricornutum in a pool with artificial seawater under natural light may serve as a basis for developing technologies for the industrial cultivation of algae.
