Abstract :
Marine organisms can be used to produce several novel products that have applications in new medical technologies, in food and feed ingredients and as biofuels. In this paper two examples are described: the development of marine drugs from sponges and the use of microalgae to produce bulk chemicals and biofuels. Many sponges produce bioactive compounds with important potential applications as medical drugs. Recent developments in metagenomics, in the culturing of associated microorganisms from sponges and in the development of sponge cell-lines have the potential to solve the issue of supply, which is the main limitation for sponge exploitation. For the production of microalgal products at larger scales and the production of biofuels, major technological breakthroughs need to be realized to increase the product yield.
