牛粪沼渣中多重耐药细菌的环境风险

Shuitu Baochi Xuebao, 2023
为研究牛粪厌氧发酵沼渣中多重耐药细菌的环境污染风险,选用畜禽养殖中常用的5种抗生素(红霉素、氨苄青霉素、金霉素、链霉素、环丙沙星)对牛粪沼渣中可培养抗生素抗性细菌进行筛选。结果表明:多重耐药细菌的比例高达76.5%,其中,抗5种和4种抗生素的细菌分别有11,21株。所有多重耐药细菌均对氨苄青霉素具有抗性,抗红霉素、金霉素和链霉素的细菌分别占总多重耐药细菌数的92.0%,89.3%,61.3%。通过细菌16S rRNA测序鉴定,32株具有4种以上抗性的细菌分别属于福氏志贺氏菌、摩根氏菌和假中间苍白杆菌 ...

Lanthanide Nanoparticles With Dual Enzyme Mimetic Activities for Targeted Treatment of Gram‐Negative Bacterial Infections

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Gram‐negative (G−) bacterial infections, fueled by intrinsic antibiotic resistance stemming from their unique outer membrane architecture, pose a critical global clinical challenge. This study introduces a pioneering dual‐enzyme‐mimetic nanotherapy based on NaYbF4 nanoparticles (NaYbF4 NPs) that achieves synergistic antibacterial and anti ...

From Tetracycline to Sulfamethoxazole: Photocatalytic Degradation and Mechanistic Insights in Aquatic Environments

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...

Accessing Ultra‐Nano Phase‐Separated Metallic Glasses via Cryogenic Cycling

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Phase separation offers a promising avenue to mitigate the inherent brittleness of metallic glasses. However, traditional approaches relying on mixing enthalpy face significant challenges, primarily due to the detrimental impact on glass‐forming ability.

Effects of Oxytetracycline on Population Growth and Genetic Diversity of Euplotesvannus (Marine Protist) [PDF]

, 2016
抗生素作为一类环境污染物在海岸带生境中广泛存在,它们对海洋原生生物遗传多样性的影响还不清楚.本工作以一种海洋纤毛虫原生生物(扇形游仆虫(Euplotes vannus))为例,研究了一种常见四环类抗生素(土霉素)对其生长的影响,并通过单细胞(个体)分析,探索了抗生素对其大核基因组中核糖体小亚基RNA基因(SSU r DNA)序列多样性的影响.结果表明,与对照组相比,3个土霉素处理组(1,10和20μg/m L)中纤毛虫的自然增长率随土霉素浓度升高显著降低,细胞大小则呈增大趋势.SSU r ...

Closing the Vicious Cycle: A Multimodal Hydrogel Targeting Hyperglycemia, Oxidative Stress, and Infection in Diabetic Wounds

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Diabetic chronic wounds, characterized by a unique pathological microenvironment including persistent hyperglycemia, excessive reactive oxygen species (ROS), bacterial infection, and sustained inflammation, exhibit notoriously impaired and delayed healing processes. This study developed a multifunctional hydrogel therapeutic system (GOx@Zn‐MPN

抗生素生产废水生化前预处理技术进展

Gongye shui chuli, 2007
抗生素生产废水是一种成分复杂、生物毒性高、色度高、含难生物降解有机物质的有机废水。现行的处理工艺大部分是采用生化处理,而抗生素生产废水可生化性较差,并有抑制好氧微生物生长的有毒有害物质,若不采取行之有效的生化前预处理工艺,往往难以达到设计效果。经过广泛研究,现已形成了大量可行的预处理技术,并已广泛应用到生产实践中,在抗生素生产废水治理中发挥了重要的作用。作者对现行各种抗生素生产废水预处理工艺进行了介绍,并提出了抗生素生产废水处理技术的发展方向。
