17.12. Different Types of Algae Cultures for Biodiesel Production
Microalgae can be cultivated in different cultures according to the algae species and the purpose of cultivation. Microalgae cultures include cultivation in open ponds, closed ponds, photobioreactors, desert-based algae cultivation, waste water, marine algae cultivation, and cultivation next to power plants.
