Researchers at the Scottish Association for Marine Science (SAMS) have unlocked a treasure chest of ‘super-algae’ that could provide a previously untapped source of oil. Using a newly devised technique, scientists examined micro-algae strains in the Culture Collection of Algae and Protozoa (CCAP), an internationally important algal store based at SAMS in Oban, to find out which ocean-based strains had the highest oil content.
