Fig. 2From: Cross-linked enzyme-polymer conjugates with excellent stability and detergent-enhanced activity for efficient organophosphate degradationThe mass ratio of PoOPHM9 to Pluronic F127 (a), the different order of adding Pluronic F127 (b) and the concentrations of ammonium sulfate (c), the free enzyme (d) and glutaraldehyde (e) were optimized for preparing the immobilized catalyst CLEPC. The immobilized enzymes were distributed in aqueous phase during the enzymatic reaction (f, left) and easily recovered by centrifugation (f, right). g The transmission electron microscopy of CLEPC showed the aggregation of immobilized enzymes with the mean diameter of 0.66 ± 0.12 μmBack to article page
