Investigation of the parameters affecting the separation of bacterial enzymes from cell debris by tangential flow filtration

The effect of organism, enzyme, method of cell breakage and membrane characteristics on the separation of bacterial enzymes from cell debris by tangential flow filtration has been studied. The effectiveness of separation was assessed by process time, enzyme yield and specific activity, and turbidity of the filtrate. For a particular organism and enzyme, method of cell breakage and membrane characteristics significantly influenced separation performance, though results indicate that it is not yet possible to optimize all aspects of performance simultaneously.
