Influence of culture conditions of Gordonia jacobaea MV-26 on canthaxanthin production

commercial interest in the use of natural pigments isolated from microorganisms has increased in recent years; hence, molecules belonging to the polyisoprenoid group (i.e.b-carotene, astaxanthin, and canthaxanthin) have been the focus of much attention. the bacterium gordonia jacobaea readily synthesizes and accumulates large amounts of canthaxanthin (b-b′-carotene-4,4′-dione), which is widely used in the food and cosmetics industries. in the present work, the effects of different low-cost raw materials on fermentation and canthaxanthin accumulation by a hyperpigmented strain of g. jacobaea were studied. canthaxanthin production and peak levels of accumulation varied according to the different media used.
