This allows the pH of the reaction to be controlled to some extent, but also results in cleaner transformations, the organism having been removed from the complex mixture of chemicals that accumulates during growth, and thus can simplify downstream processing of reaction products. 2 Isolated enzymes In this case, the enzyme required for biotransformation is liberated from the cells by cell disruption and then purified to the required degree using a range of chromatographic techniques. Of course, in many instances, the isolation and purification has been performed by an enzyme supplier and the isolated enzyme is provided to the researcher in a usable powdered form that may be employed in much the same way as a conventional chemical reagent from the shelf.
