Abstract
The application of aqueous two-phase extraction
for the downstream processing of lipase has been exploited.
The influence of system parameters such as phase forming
salts, molecular weight of the phase forming polymer,
system pH, tie line length, and phase volume ratio on the
partitioning behavior of lipase was evaluated. The aqueous
two-phase system consisting of PEG6000 and disodium
phosphate (Na2HPO4) resulted in one-sided partitioning of
lipase with partition coefficient 0.11, activity recovery
116%, and purification factor of 2.25. Further, the purity
of lipase was increased to 3.59-fold using multi-stage
extractions.
