“…There are different classes of antibiotics based on their mechanism of action, chemical structure, action spectrum, and route of administration (Ilurdoz et al, 2022). The most common classification of antibiotics is based on their mode of action, which includes fluoroquinolones, quinolones, β-lactams, sulfonamides, monobactams, carbapenems, and aminoglycosides.…”

“…The most common classification of antibiotics is based on their mode of action, which includes fluoroquinolones, quinolones, β-lactams, sulfonamides, monobactams, carbapenems, and aminoglycosides. Quinolones (ciprofloxacin, levofloxacin, norfloxacin, and ofloxacin) are broad-spectrum antibiotics that are widely prescribed (Ilurdoz et al, 2022). More importantly, CIP stands in the first place based on the number of antibiotics prescribed in this group (Movasaghi et al, 2019).…”

“…CIP prevents the replication of bacteria and ultimately inhibits their proliferation (Adaobi et al, 2021). Due to its wide consumption as a broadspectrum drug (Ilurdoz et al, 2022), incomplete metabolism(15-20%) in humans and animals (Movasaghi et al, 2019;Laurent et al, 2000), higher environmental concentration (up to 20,321 ng L -1 ) and frequent detection in the environment (Ilurdoz et al, 2022) (Movasaghi et al, 2019;. CIP has become one of the top priority water contaminants that needs research intervention.…”

Contamination of water by ciprofloxacin has become a significant concern due to its adverse health effects and growing evidence of antimicrobial-resistant genes evolution. To this end, a chemically modified bamboo biochar was prepared from bamboo sawdust to effectively remove ciprofloxacin (CIP) from an aqueous solution. Under similar adsorption conditions, the modified bamboo biochar (MBC) has an excellent CIP removal efficiency (96%) compared to unmodified bamboo biochar (UBC) efficiency (45%). Thus, MBC was used in batch adsorption experiments and the process was optimized with the central composite design (CCD) framework of response surface methodology (RSM). Sorption process parameters such as initial CIP concentration, pH, adsorbent dose, and contact time were studied and found to have a significant effect on CIP removal. The optimal CIP removal (96%) was obtained at MBC dose (0.5 g L-1), CIP initial concentration (20 mg L-1), pH (7.5), and contact time (46 min). The adsorption kinetic data were well described by the pseudo-second-order model (R2 = 0.999), and both Langmuir (R2 = 0.994) and Freundlich (R2 = 0.972) models gave the best fit in CIP adsorption isotherm analysis. The maximum monolayer adsorption capacity of the MBC was 78.43 mg g-1 based on the Langmuir isotherm model. These results suggest that CIP adsorption was mainly controlled by chemisorption. Moreover, the CIP adsorption process was endothermic and spontaneous. Overall, MBC is a low-cost, efficient, and recyclable adsorbent for eliminating emerging contaminants such as ciprofloxacin from an aqueous solution.

“…Antibiotics in the aquatic environment are also due to their overuse in clinical contexts. Because humans excrete large amounts of drugs or their biologically active derivatives through urine or faeces, antibiotics end in wastewater treatment plants where they are hardly eliminated [ 5 ]. The wastewater undergoes biological treatment with bacteria, and this is ineffective when the complete elimination of antibiotics is intended [ 6 ].…”

This work describes a novel sensing system using eggshells as substrate for the first time, targeting the detection and semiquantitative determination of antibiotics in waters from aquaculture, enabling simple, inexpensive, and in situ drug monitoring. Eggshell was ground and the resulting powder was modified by adsorption of suitable reagents, and it takes a typical colour after contact with the antibiotic. The colour intensity is correlated with the concentration of the antibiotic. This novel approach was applied to oxytetracycline, one of the antibiotics commonly used in aquaculture. The chemical changes on the eggshell powder were evaluated and optimised to produce an intense colour change as a function of the concentration of the antibiotic. The colour changes were evaluated by visual comparison with images taken with a digital camera, applying an appropriate mathematical treatment to the colour coordinates of the HSL system used by Windows. The selectivity of the response was tested against other antibiotic drugs. The materials were also used in the analysis of a spiked environmental water sample. Overall, this work presents a rapid, inexpensive, simple and equipment-free method for screening and discrimination of tetracycline drugs in aquaculture. The method is a green approach by reusing eggshells and decreasing the level of contamination correlated to analytical methods, thus being a promising tool for local, rapid, and cost-effective antibiotic monitoring.

“…Studies on antibiotics have drawn much attention due to the high detection frequency of antibiotics in the environment [ 1 , 3 , 4 , 5 ]. The detection of antibiotics in the environment is found to be in the range of ng/L and µg/L, and even mg/L [ 6 , 7 ].…”

Evaluating the Biodegradation of Veterinary Antibiotics Using Kinetics Model and Response Surface Methodology

et al. 2022

The inappropriate use and indiscriminate disposal of antibiotics has become a menace worldwide. The incomplete removal of these contaminants from wastewater treatment plants has also contributed to this. This study presents the biodegradation of two veterinary antibiotics; ciprofloxacin (CIP) and enrofloxacin (ENRO). Kinetics models were explored to understand the dynamics of biodegradation in an anaerobic digestion process. This was carried out in batch reactors under various operating conditions: pH, organic loading rate (OLR), and antibiotic concentration. The influence of the parameters was investigated using a response surface methodology (RSM) based on the Box–Behnken experimental design of 15 runs. The data obtained were fitted on a polynomial function model. OLR and pH exhibited a synergistic and antagonistic effect in the response models developed, with a high correlation regression coefficient (R2; 0.9834–0.9875) close to 1 at a 95% confidence level. The optimum conditions obtained from the RSM numerical optimization were pH (6), OLR (2 kgCOD·m−3·days−1), and an antibiotic concentration of 75%, which gave the removal of CIP, ENRO, and COD, respectively, as 80%, 83%, and 73% at a desirability function of 85%. The kinetics study shows that the biodegradation of antibiotics was well fitted on a first-order model (R2; 0.9885–0.9978) with rate constants ranging from 0.0695 to 0.96 days−1.
