AI Article Synopsis
- Antibiotics are now considered environmental pollutants due to their widespread use, prompting the need for effective removal methods from water.
- A novel type of annular mesoporous carbon (MCN) was developed using phenolic resin and F127 triblock copolymer, showing high surface area and pore volume for better adsorption of antibiotics like penicillin, streptomycin, and tetracycline.
- MCNs demonstrated a high removal efficiency of 99.6% and an exceptional adsorption capacity of up to 880.6 mg/g for tetracycline, indicating their significant potential for treating antibiotic-contaminated water.
Article Abstract
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.

, commonly known as , is a critical zoonotic pathogen that significantly reduces milk yield and product quality and poses a significant risk to public health. Although is increasingly recognised as a principal agent causing milkborne infections, research dedicated to this pathogen in dairy cattle has been less extensive than that of other pathogens. This study aimed to examine the antibiotic resistance profiles of derived from dairy cows and assess its pathogenicity using validated in vivo models.

Bacterial resistance, a global public health concern prioritized by the World Health Organization, is particularly alarming in Staphylococcus aureus and Escherichia coli. Urgently addressing this, the search for new antibiotics has turned to plant essential oils. Our study focused essential oils derived from Colombian plants Croton killipianus, Croton smithianus, Croton leptostachyus, Croton hondensis, and Croton gossypiifolius.
