In this paper the partitioning behavior of laccase from a culture supernatant of a Pleurotus sapidus fermentation in an aqueous two-phase system (ATPS) of polyethylene glycol with a molecular weight of 3000 g/mol (PEG 3000). potassium and sodium phosphate and sodium chloride is experimentally investigated. Results show that enzyme activity is retained during aqueous two-phase extracti... https://parisnaturalfoodes.shop/product-category/ezee-flow-tea/
