Algal biomass is a source of high value products worth over A$100 x 10 6 per annum. Red and brown seaweeds yield the phycocolloids, which are used as gelling, viscosity and clarifying agents in the food, cosmetic and pharmaceutical industries. Microalgal products in the health food market include Spirulina and Chlorella powder and tablets. The blue phycocyanin pigment extracted from Spirulina is used as a food colouring, and P-carotene extracted from Dunaliella salina, is sold as a yellow food colouring, and for its provitamin A and anti-oxidant properties in nutritional supplements. Development of new intensive culture systems is expected to widen the range of commercial algal products in the future.
