Cryopreservation has been successfully used in the banking and maintenance of cultures of microorganisms, from bacteria to yeasts, since the onset of cryobiology. Biobanking of marine biological resources is crucial for development of scientific knowledge as researchers rely on guaranteed access to reliable, stable resources. Culture collections play a key role in the provision of marine biological resources as they ensure long-term ex situ storage of biological resources that are made available for public and private sector research and education. In this chapter, we provide protocols for cryopreservation of different types of algae cultures.
