| Abstract | The feasibility of producing natural beta-carotene from open-air pond cultures of the microalga Dunaliella salina has been investigated for the past 6 years at Hutt Lagoon, Western Australia. A production plant with over 25ha of ponds was opened in late 1986 and is now in full production. No reduction in productivity has been observed in the scale-up from pilot-scale ponds to the current 50 000m² production ponds. The algae are grown in high salinity brine in shallow ponds formed by building earthen walls on the floor of a pristine salt lake. Methods have been developed for harvesting the algae from the brine, and extracting the beta-carotene from the algae. Several beta-carotene containing products are available, these include beta-carotene in oil for the food and pharmaceutical industries, and dried algal powder for prawn feed. |
