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. 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.

Influence of culture conditions of Gordonia jacobaea MV-26 on canthaxanthin production / Influencia de las condiciones de cultivo de Gordonia jacobea MV-26 en la producción de cantaxantina

El interés comercial del uso de pigmentos naturales aislados a partir de microorganismos se ha incrementado en los últimos años y las moléculas pertenecientes al grupo de los poliisoprenoides (p.e. β-caroteno, astaxantina y cantaxantina) se han convertido en un foco de atención. La bacteria Gordonia jacobaea es capaz de sintetizar y acumular grandes cantidades de cantaxantina (β-β’ -caroteno-4,4’ -diona), muy usada en la industria alimentaria y de cosméticos. En este trabajo estudiamos la influencia de diferentes materias primas de bajo coste en la fermentación y la acumulación de cantaxantina por una cepa mutante hiperpigmentada de G. jacobaea. Se ha observado que la producción de cantaxantina y el momento en el que se alcanza la máxima producción varía según los diferentes medios empleados (AU)
