The influence of rotating magnetic field on bio-catalytic dye degradation using the horseradish peroxidase

The aim of this study was to analyze the effects of a rotating magnetic field (RMF) on the activity and stability of horseradish peroxidase (HRP) and the catalyzed enzymatic process. It was found that 8 h of exposure to RMF does not influence the operational stability of HRP. At the same time, it was observed that the RMF improved HRP activity in a wider range of pH: 49% and 68% at pH 6.5 and pH 7.0, respectively. The efficiency of the catalyzed enzymatic process under exposure to RMF was analyzed by two-dimensional correlation analysis (2DCorr) on the example of the Remazol Brilliant Blue R (RBBR) decolorization process. The obtained results indicated the influence of RMF on the intensification of this process. Our studies showed an alternative method of enzymatic process intensification, which is significant in science and has practical value for applications.
