Application parameters of laccase–mediator systems for treatment of sulfonamide antibiotics

Optimization of the enzymatic elimination of flumequine by laccase-mediated system using response surface methodology

“…Due to the high redox potential (1.8 V), ABTS is one of the most efficient mediators that has been successfully applied for elimination of 2,4-dinitrophenol [37], sulfonamide antibiotics [13,14], benzodiazepines [22], and synthetic acid dye [38]. The result of ABTS influences on the removal efficiency is in agreement with those obtained by other researchers [13,14,22]. As shown in Figs.…”

“…Laccases catalyze the oxidation of a wide range of substrates such as ortho-and para-diphenols, aromatic amines, phenolic acids, methoxy-substituted phenols, and several other compounds coupled to the reduction of molecular oxygen to water. The range of compounds oxidized by laccase can be expanded in the presence of appropriate redox mediators such as 1-hydroxybenzotriazole, violuric acid, and ABTS [10,13,14]. In recent studies, laccase was successfully used for the elimination of synthetics dye [15,16], antibiotics [13,17], triclosan [18][19][20], anthracene [21], benzodiazepines [22], pesticide [23], and several other contaminants from aqueous solution.…”

Fungal Bioremediation of Emerging Micropollutants in Municipal Wastewaters

“…The presence of ABTS enhanced transformation of dymron (Maruyama et al 2006), TCS (Kim and Nicell 2006a), sulfonamide 14 antibiotics (Weng et al 2013), BPA Nicell 2006b, Macellaro et al 2014) and parabens analogues (Macellaro et al 2014). On the other side HBT was found to be fundamental during laccase treatments of carbamazepine , iso-butylparaben and n-butylparaben (Mizuno et al 2009), anti-inflammatories and estrogens (Lloret et al 2010) and tetracycline antibiotics (Suda et al 2012).…”

“…Luminescent bacteria V. fischeri (UNI EN ISO 11348-3) was used for the conversion of NP by 4 fungi (Soares et al 2006), BPA and TCS by laccases from T. versicolor (Kim and Nicell 2006c), sulfonamide antibiotics by laccases from Perenniporia sp. (Weng et al 2013), naproxen (Marco-Urrea et al 2010b) and several pharmaceuticals and recognized EDCs by laccases from T. versicolor (Cruz-Moratò et al 2014). …”

“…Laccase-catalyzed system was studied over a pH range 5-9 and set at 6 for natural estrogens (estrone, 17β-estradiol and estriol) and synthetic estrogen (17α-ethinylestradiol) (Auriol et al 2007). The optimal pH range of 4-6 was observed for the transformation of dymron (Maruyama et al 2006), TCS Nicell 2006a, Margot et al 2013), sulfonamide antibiotics (Weng et al 2013), anti-inflammatory pharmaceuticals (Margot et al 2013) and BPA Nicell 2006b, Margot et al 2013).…”
