Biotechnology: developing high-yield algae

High-yielding microalgae

The Culture Collection of Algae and Protozoa (CCAP) at the Scottish Association for Marine Science (SAMS) holds the largest algal culture collection in Europe, some 2700 strains, from which all suitable candidate strains will be screened.

Lead scientist in CCAPInitially these will be grown on a small scale at SAMS in enclosed systems. Additional work will focus both on industrial sites and on artificial blooms with fixed conditions.


There are THREE KEY REQUIREMENTS for biodiesel production:

  • sustainable production of high-oil-yielding microalgae strains: this is the critical requirement
  • extraction of the oil from the algae 
  • conversion of microalgal oil into biodiesel

BioMara will investigate these key requirements.

Cultivating seaweeds

Here the spores germinate to form tiny plants 2mm long, which are transferred to sea after two months then harvested six to eight months later, when they will have attained a length of over two metres.
