Biodegradation of the veterinary antibiotics enrofloxacin and ceftiofur and associated microbial community dynamics

Responses of the Endophytic Bacterial Communities of Juncus acutus to Pollution With Metals, Emerging Organic Pollutants and to Bioaugmentation With Indigenous Strains

“…Members of the family Methylophilaceae has been found to exhibit higher abundances in metal polluted soils ( Kou et al, 2018 ). Increase in the abundance of the families Burkholderiaceae and Xanthobacteraceae has been demonstrated in the enrofloxacin and ceftiofur acclimated communities from rhizosphere sediments of CWs ( Alexandrino et al, 2017 ). It is important to mention that the abundance of ASVs affiliated with the family Pseudomonadaceae decreased significantly in the roots exposed to low and high pollution although this family is frequently isolated from plants at polluted sites ( Afzal et al, 2014 ).…”

Assessing the Photocatalytic Degradation of Fluoroquinolone Norfloxacin by Mn:ZnS Quantum Dots: Kinetic Study, Degradation Pathway and Influencing Factors

“…From the absorption spectra, the absorbance of NOFX is gradually decreased with irradiation time. The effect of various process parameters, such as solution pH, catalyst dose and initial drug quantity on the degradation efficiency of NOFX was assessed by varying pH (2)(3)(4)(5)(6)(7)(8)(9)(10)(11), catalyst dose (20-90 mgs), maintaining the fixed drug concentration (15 mg/L). Figure 10a shows that about 86% NOFX (15 mg/L, pH 10) was decomposed in the presence of the photocatalyst Mn:ZnS QDs (60 mgs) after 60 min of UV light exposure.…”

“…A very small amount of antibiotic left-overs in the environment can cause eutrophication in ecosystems and infectivity in foodstuffs and drinking water sources [3][4][5]. A number of treatment processes dealing with antibiotic residuals have extensively been explored, such as electrolysis [6], microbial degradation [7], biodegradation [8], nanofiltration [9,10], activated carbon adsorption [11,12], and ozonation [13]. Those procedures showed different degrees of success in removing low concentrations of many organic compounds.…”

Dispersed GaOOH rods loaded on the surface of ZnBiNbO5particles with enhanced photocatalytic activity toward enrofloxacin

“…In recent years, veterinary drugs have been widely and commonly used to treat many animal diseases. [1][2][3] Antibiotics are among the most widely used veterinary drugs because antibiotics can not only treat and prevent animal diseases, but also promote animal growth and improve the nutritional value of animal foods. 4,5 Among these, enrooxacin is a uoroquinolone antibiotic that is the most commonly used antibacterial compound in veterinary applications.…”
