“…Advantages of biotechnological production include the ability of microorganisms to use low cost substrates, the optimized control of cultivation, minimized production time and the natural origin of the synthesized dyes (Wu Sperstad et al (2006) and Eldahshan and Singab (2003). and Liu, 2007;Tinoi et al, 2005).…”

Carotenoids are natural pigments that can be synthesized by various microorganisms, including bacteria, yeasts, filamentous fungi and microalgae. These pigments comprise around 700 different structures with peculiar colors and biological properties that are beneficial to health. Advantages of biotechnological production of carotenoids include the ability of microorganisms to use low cost substrates, the optimized control of cultivation, minimized production time and the natural origin of the synthesized pigments. Techniques for separation and purification of carotenoids are well established at laboratory scale, however the development of processes that can be economically scaled-up is essential for industrial production.

This work aimed at screening microorganisms capable of producing carotenoids. Microorganisms were isolated from soil, leaves, fruits, flowers, agro-industrial wastes, and processed product in decomposition and then grown in an orbital shaker, using 10% (w/v) of inoculum (25 8C, 180 rpm for 48 h) and incubated for 120 h in a dark room. A total of 116 microorganisms were isolated and screened: 16 yeasts, 65 bacteria, and 35 fungi. Three yeasts demonstrated great potential to produce red carotenoids, with a total carotenoid content of 707-818 mg L 71 (99-263 mg g 71 ). One filamentous fungus and two bacteria produced mostly yellow pigments in a final concentration ranging from 1063 to 2563 mg L 71 (239-2310 mg g 71 ). From 116 isolated microorganisms, several of them showed potential for production of carotenoid-synthesizing activity. RAPD analysis was used to check the genetic differences between the screened strains, showing that all microorganisms were from different species.Keywords: screening; microorganisms; carotenoids; industrial residues; RAPD El objetivo de este trabajo fue examinar los microorganismos capaces de producir carotenoides. Microorganismos de tierra, hojas, frutos, flores, residuos agro-industriales y producto procesado en descomposicio´n se aislaron y se cultivaron en un agitador orbital, usando 10% (w/v) de ino´culo (25 8C, 180 rpm durante 48 horas) e incubados durante 120 h en una habitacio´n oscura. Se aislaron y examinaron un total de 116 microorganismos, 16 levaduras, 65 bacterias y 35 hongos. Tres levaduras demostraron un gran potencial para producir carotenoides rojos, con un contenido total de carotenoides de entre 707 a 818 mg L 71 (de 99 a 263 mg g 71). Un hongo filamentoso y dos bacterias produjeron en su mayorı´a pigmentos amarillos en una concentracio´n final de entre 1063 a 2563 mg L 71(239 a 2310 mg g 71 ). De 116 microorganismos aislados, varios de ellos mostraron potencial para la produccio´n de actividad sintetizadora de carotenoides. Se uso´el ana´lisis RAPD para revisar las diferencias gene´ticas entre las cepas examinadas, mostrando que todos los microorganismos eran de diferentes especies.

“…These microorganisms also produce carotene, although in smaller amounts. The total production and the proportion of the three carotenoids depend on the incubation conditions (Tinoi et al 2005). Torularhodin shows a considerable antioxidant activity (Breierová et al 2008) that helps the stabilization of membranes under stress conditions (Gorbushina et al 2008).…”
