摘要：

HPLC testing of the carotenoid content of the halobacteria Halobacterium salinarium, Haloarcula hispanica and Haloferax mediterranei showed that all contained high amounts of ketocarotenoids, Halobacterium salinarium produced 2400 mu g of total carotenoids per gram of dried bacteria, including 265 mu g of trans-astaxtanthin (11%), and 588 mu g of 3-hydroxy-echinenone (24%). The biotechnological properties of Halobacterium salinarium as a natural pigment source are also presented. The results are compared with those from the yeast Phaffia rhodozyma,ma currently used in the industry as a source of trans-astaxanthin.
