RESUMO
A bacterium capable of producing Coenzyme Q10 (CoQ10, was isolated from soil. Based on analysis of the 16S rDNA sequence, traditional physiological characteristics, and Biolog-GN, the strain was belonging to the genus Sphingomonas and named as Sphingomonas sp. ZUTEO3. The optimum fermentation condition of CoQ10 production was as following: glucose 15 g/L, (NH4)2SO4 10 g/L, original pH 8.0 and at 25 degrees C. The addition of solanesol could improve CoQ10 production. The optimal condition for the bioconservation from solanesol to CoQ10 was as following: adding 0.75 g/L of raw solanesol after the first 12 h fermentation and continued for another 12 h fermentation. The maximal yield of CoQ10 reached 96.88 mg/L.
