Immobilization of horseradish peroxidase onto Purolite® A109 and its anthraquinone dye biodegradation and detoxification potential

Abstract: Horseradish peroxidase (HRP) is a highly specific enzyme with great potential for use in the decolorization of synthetic dyes. A comprehensive study of HRP immobilization using various techniques such as adsorption and covalent immobilization on the novel carrier Purolite® A109 with a special focus on enzymatic decolorization and toxicity of artificially colored wastewater. The immobilized preparations with an activity of 156.21 ± 1.41 U g−1 and 85.71 ± 1.62 U g−1 after the HRP adsorption and covalent immobili… Show more

“…The maximum capacity of HRP adsorption on kaolin has been found to be 4.63 mg/g [53]. However, when comparing the activity of HRP-MAB with values achieved in the literature for the same type of HRP, similar or better results have been described by several researchers, ranging from ~5 to ~85 U/g [13,53]. Steric problems frequently associated with high loadings on the carrier are a possible explanation for discrepancy from some expected values.…”

“…These results are similar to or favorable compared with those reported in the literature for HRP immobilized on other carriers. For the purpose of comparison, a maximum HRP binding of 4.8 mg/g and 3.3 mg/g has been achieved on a commercial resin (Purolite®A109) by adsorption and covalent immobilization, respectively [13]. The maximum capacity of HRP adsorption on kaolin has been found to be 4.63 mg/g [53].…”

“…After the detailed examination of differential genes and pathway expression, the genes involved in the possible mechanism of enhanced dye removal performance by FG were generally divided into three groups. The first group was extracellular non-specific peroxidase, including LiP, MnP, Lac, and DyP, which have been considered as the main participants in the biodegradation process of anthraquinone synthetic dyes ( Hsu et al, 2012 ; Uchida et al, 2015 ; Navada et al, 2018 ; Sekuljica et al, 2020 ). Previous research has tended to focus on a single enzyme involved in the dye biodegradation process.…”

“…Peroxidases are another group of enzymes that can catalyze oxidation reactions. Peroxidases immobilized on various kinds of supports have been successfully utilized for the decolorization and detoxification of waste dyes [23,[58][59][60]. Many researchers have also used horseradish peroxide (HRP) in the degradation of organic dyes.…”
