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. beta-carotene, astaxanthin, and canthaxanthin) have been the focus of much attention. The bacterium Gordonia jacobaea readily synthesizes and accumulates large amounts of canthaxanthin (beta-beta'-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.
近年来，对利用从微生物中分离出的天然色素的商业兴趣有所增加；因此，属于聚异戊二烯类的分子（即β-胡萝卜素、虾青素和角黄素）备受关注。雅各布戈登氏菌能轻易合成并积累大量角黄素（β,β'-胡萝卜素-4,4'-二酮），其在食品和化妆品行业有广泛应用。在本研究中，研究了不同低成本原料对一株色素沉着的雅各布戈登氏菌发酵及角黄素积累的影响。角黄素的产量和积累峰值水平因所用不同培养基而异。
