The purpose of this study will focus on separation from the fermentation broth and purification of CoQ10 that produced by Rhodobacter sphaeroides BCRC 13100. Three topics were discussed as follows:(1) Disruption methods:the cells were disrupted by using enzyme, freezing and heating, chemicals or high press homogenizer. The results showed that the product yield could achieve 2.85 mg/g-DCW for enzyme method but its cost was higher. Secondly, the method of high press homogenizer was better that the product yield can achieve 2.11 mg/g-DCW. On the other hand, the ethanol could be used to disrupt and extract directly. The product yield could also achieve 2.01 mg/g-DCW. (2) Separation methods:CoQ10 was quantitatively extracted with various organic solvents. Using ethanol twice extraction could separate the products to release into the surrounding solution.CoQ10 was extracted by ethanol at 40℃ for 30min. The product yield could also achieve 2.46 mg/g-DCW. The product yield of ethanol disrupted method is 0.86 fold of the product yield using enzyme method. (3) Purification method:The crude extract was purified by silica gel column chromatography. Another method was liquid-liquid extraction with hexane. After crystallization, the purity determined by means HPLC could achieve 96.9%. Ho-Shing Wu 吳和生 2007 學位論文 ; thesis 79 en_US |
