Possibility of phenylacetic acid separation by electrodialysis after bioproduction
Original language description
Phenylacetic acid is a compound with characteristic honey-like scent with wide application in cosmetics and food industry. In the pharmaceutical industry phenylacetic acid is used as a precursor in the production of penicillin-G and diclophenac. Recently a lot of focus was dedicated to the biotechnological production of phenylacetic acid, because it is produced at more environmental-friendly conditions and such product can be labeled as natural. Phenylacetic acid is produced by Gluconobacter oxydans from 2-phenylethanol in non-growth conditions in a medium consisting mainly of phosphate buffer. Since at the end of the bioproduction phenylacetic acid is present in the buffer solution containing different salts and some other organic impurities an electrodialysis can be applied for its separation. Separation of phenylacetic acid from this solution is performed in two steps, where at the first step organic impurities are removed and in the second step demineralization of the acid is performed. The two-step separation was experimentally examined, and the solution obtained in the first step was further processed in the second step of separation.
