Characterization of the three-phase partitioned laccase from Trametes versicolor strain with antiproliferative activity against breast cancer cells.

An extracellular laccase from T. versicolor was 20.4-fold purified by three-phase partitioning with high recovery (245 %) and biochemically characterized in detail for the first time.

Partial characterization of Bacillus pumilus catalase partitioned in poly(ethylene glycol)/sodium sulfate aqueous two-phase systems.

Aqueous two-phase partitioning system (ATPS) was used to extract and purify catalase from Bacillus pumilus. The system parameters for effective purification of catalase were optimized. The best catalase recovery (123%) with a 4.
