Antibiotics have become a new type of environmental pollutant due to their extensive use. High-performance adsorbents are of paramount significance for a cost-effective and environmentally friendly strategy to remove antibiotics from water environments. Herein, we report a novel annular mesoporous carbon (MCN), prepared by phenolic resin and triblock copolymer F127, as a high-performance adsorbent to remove penicillin, streptomycin, and tetracycline hydrochloride from wastewater. The MCNs have high purity, rich annular mesoporosity, a high surface area (605.53 m/g), and large pore volume (0.58 cm/g), improving the adsorption capacity and facilitating the efficient removal of penicillin, streptomycin, and tetracycline hydrochloride from water. In the application of MCNs to treat these three kinds of residual antibiotics, the adsorption amounts of tetracycline hydrochloride were higher than penicillin and streptomycin, and the adsorption capacity was up to 880.6 mg/g. Moreover, high removal efficiency (99.6%) and excellent recyclability were achieved. The results demonstrate that MCN adsorbents have significant potential in the treatment of water contaminated with antibiotics.

Recently, extensive use of antibiotics has increased the amount of antibiotic residues in the natural water environment. This study presents an experimental investigation into the degradation of penicillins, tetracyclines, streptomycin and chloramphenicol in aqueous solutions when exposed to 1 MeV accelerated electrons with doses of 0.1, 1, 3 and 7 kGy using HPLC-HRMS analysis.

Background: Goats can serve as an efficient animal model to study antimicrobial resistance. The present study was undertaken with an aim to assess the status of antibiotic resistance associated with caprine mastitis in the Bathinda district of Punjab.
Methods: Milk samples were collected aseptically from the cases of clinical mastitis in goats followed by bacterial isolation and antibiotic susceptibility testing for amikacin, amoxicillin, amoxyclav, ampicillin, ampicillin-sulbactam, cefoperazone, cefoperazone-tazobactam, ceftizoxime, ceftriaxone, ceftriaxone-sulbactam, ceftriaxone-tazobactam, ciprofloxacin, colistin, doxycycline, enrofloxacin, erythromycin, gentamicin, moxifloxacin, ofloxacin, oxytetracycline, penicillin-G, streptomycin and tetracycline.

Clostridium perfringens induced necrotic enteritis (NE) became a persistent problem that had a major financial impact on the poultry business worldwide. Nevertheless, no prior research has assessed the related risk factors in Egyptian broiler farms. Thus, the purpose of this study is to perform an epidemiological analysis of C.

Studies on the bioconversion of CO to CH using Fe have reported that a fraction of CO is converted to FeCO, forming a passivation layer on the Fe surface, which reduces its reactivity and limits process efficiency. To mitigate FeCO precipitation and enhance CO-to-CH conversion using Fe, this study evaluates the role of citric acid (CA) as a ligand to Fe, which helps maintain iron in a soluble form and prevents its rapid conversion to insoluble iron carbonate (FeCO). Batch experiments with 30 mM Fe, anaerobic granular sludge (AGS), and NaHCO with CA as a ligand showed that citrate biodegraded into acetic acid and CO gas.

Antibiotics are routinely added to mammalian cell culture media to prevent bacterial growth. However, the use of antibiotics in cell culture can confound downstream experimental results. While genomic and transcriptomic differences between cell cultures treated with and without antibiotics are well-documented, far fewer, if any, comprehensive proteomic comparisons on the use of antibiotics in cell culture have been performed.
