Plasma-driven biocatalysis with the capillary plasma jet and rAaeUPO immobilized on Purolite beads.
The substrate ETBE was converted by rAaeUPO immobilized on Purolite ECR8309F and ECR8285. The reaction solution contained 5 ml potassium phosphate buffer (100 mM, pH 7) with 50 mM ETBE. H2O2 was generated by plasma treatment with the capillary plasma jet and a water concentration of 6400 ppm in the feed gas at 6 W plasma power. Every 5 min aliquots were withdrawn for product analysis by GC. Means and standard deviations represent three experiments.
