The present invention relates to the isolation of carotenoids and in particular the xanthophyll zeaxanthin (zeaxanthin-&bgr;,&bgr;-Carotene-3,3′-diol) and optionally other carotenoids such as lycopene, &bgr;,&bgr;-carotene, 3′-hydroxyechinenone &bgr;-cryptoxanthin and the colourless carotenoids, phytoene and phytofluene from a marine bacterium belonging to the genus Algibacter which is capable of producing the aforementioned compounds. The present invention also provides a strain of Algibacter which is capable of producing significant levels of carotenoids, especially zeaxanthin at high purity, as well as methods of using the Algibacter strain and uses of the carotenoids produced.
