This study examined the use of modified multiwall carbon nanotubes (M-MWCNTs) with immobilized laccase (L@M-MWCNTs) for removing ciprofloxacin (Cip), carbamazepine (Cbz), diclofenac (Dcf), benzo[a]pyrene (Bap), and anthracene (Ant) from different water samples. The synthesized materials were characterized using an array advanced analytical techniques. physical immobilization onto M-MWCNTs was confirmed through Scanning electron microscope (SEM)-dispersive X-ray spectroscopy (EDS) analysis Brunner-Emmet-Teller (BET) surface area measurements. specific decreased by 65% upon immobilization. There also increase in nitrogen content seen EDS asserting successful results Boehm titration Fourier transform infrared (FTIR) exhibited acidic functional groups after L@M-MWCNTs storage two months maintained 77.8%, 61.6%, 57.6% its initial activity 4 °C, 25 35 respectively. In contrast, free 55.3%, 37.5%, 23.5% at MWCNTs improved storability widened working temperature range laccase. optimum removal conditions studied pollutants pH 5, 1.6 g/L M-MWCNTs. These parameters led to >90% targeted four treatment cycles both synthetic spiked lake water. demonstrated consistent up five even wastewater. adsorption endothermic followed Langmuir isotherm. Oxidation, dehydrogenation, hydroxylation, ring cleavage seem be dominant degradation mechanisms.

Bjerkandera adusta TM11 for the bioremediation of fluoroquinolone antibiotics spiked in wastewater: A sustainable approach to pharmaceutical contaminant biotransformation

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 291, P. 117898 - 117898

Published: Feb. 1, 2025

Global antibiotic consumption is increasing dramatically. Antibiotic release into the environment, primarily through wastewater discharge, has serious impacts for human and animal health microbial ecosystems. To address this issue, white-rot fungi present a promising solution, as they possess oxidative enzymes that can degrade these pollutants. Here we investigated effectiveness of fungus Bjerkandera adusta TM11 removing three persistent fluoroquinolone antibiotics, i.e. levofloxacin, ciprofloxacin, enrofloxacin, in real wastewater. The antibiotics were added to separately at concentration 30 mg/L together cocktail 10 mg/L, then incubated 9 days. LC-MS/MS analysis anti-microbial assay (against Escherichia coli) demonstrated complete removal levofloxacin by day 7. However, ciprofloxacin enrofloxacin biotransformed degradation products still had antimicrobial activity, with efficiencies reaching 82 % 99 %, respectively, Proteomic identified 21 fungal heme peroxidases. Versatile peroxidase was most strongly-produced enzyme potentially involved biotransformation. Degradation characterized analysis, pathway proposed based on findings.
