چکیده انگلیسی
A downstream process strategy for a whole microbial transformation to produce l-phenylacetylcarbinol (PAC) in a nonionic surfactant Triton X mediated cloud point system was developed. By application of a Winsor I microemulsion, the product and the nonionic surfactant in the microbial transformation broth was separated successfully. Then the nonionic surfactant was recovered with a Winsor II microemulsion. In a single stage Winsor I microemulsion extraction process, the product recovery ratio 76.9% and the nonionic surfactant recovery ratio 66.5% were achieved. A discrete countercurrent extraction operation was also carried out to improve the separation efficiency. Finally, character of the recovery nonionic surfactant was also examined.
