NOVEL CAROTENOID-PRODUCING BACTERIAL SPECIES AND PROCESS FOR PRODUCTION OF CAROTENOIDS USING SAME

摘要

A novel Paracoccus species type strain DSM 11574 which produces and secretes carotenoids such as beta -carotene, echinenone, beta -cryptoxanthin, canthaxanthin, adonirubin, cis-adonixanthin, adonixanthin, astaxanthin and zeaxanthin in vesicles; carotenoid containing vesicles; and a process for production of carotenoids including the steps of (a) culturing a bacterial species in a nutrient medium including sources of carbon, nitrogen and inorganic substances; and (b) recovering an individual carotenoid pigment or a mixture of carotenoid pigments from cells, vesicles secreted therefrom and/or medium.
