Screening and degradation characteristics of a tetracycline-degrading bacterial strain
, 2018 四环素类抗生素在畜禽养殖业中的大量使用给生态环境带来了严重危害.从活性污泥中筛选到一株对四环素具有良好降解能力的高效降解菌株,命名为TTC-1.形态观察、革兰氏染色及16S rRNA序列分析表明该菌株为革兰氏阴性菌,并鉴定为克雷伯氏菌(Klebsiella pneumoniae).采用单因素试验分别研究温度、初始pH、接种量、金属盐种类等因素对该菌株四环素降解效率的影响.基于单因素试验结果,通过响应面优化该菌的四环素降解条件,拟合得到二次多项回归模型,确定了降解四环素的最佳条件为温度34.4 ℃,pH ...

A Mini Review of Scientific Designs of Dynamic Responsive Fluids in Battery Technologies
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Dynamic responsive fluids are emerging as transformative elements in the evolution of battery technologies, marking a pivotal shift from static passive designs toward systems that actively sense and adapt to their operating environments. By integrating dynamic responsive fluids, batteries can interact with both internal and external stimuli in

Shuitu Baochi Xuebao, 2019 为探究兽用四环素对玉米幼苗生理特性的影响，通过玉米盆栽试验，研究四环素外源污染胁迫下施用不同基质（单施蚯蚓粪、菌糠、菌剂、生物炭及其与菌剂配施）对玉米生长的影响。结果表明，四环素对玉米生物量有明显的抑制作用，其中对根长的抑制作用显著大于株高，而添加不同基质均能缓解四环素对玉米株高和根长的抑制作用，且JK和JJ处理效果最显著，升幅分别为17.29%和30.08%；四环素显著诱导玉米SOD活性上升，升幅为3.34%，抑制CAT和POD活性，降幅分别为10.98%和46.68%，添加不同基质处理中 ...

Gongye shui chuli, 2017 以农业废弃物玉米苞叶为原料，用氯氧化锆对其进行改性，用于去除水体中的四环素。采用SEM、FTIR对改性前后的玉米苞叶进行了表征，并研究了溶液初始pH、温度等因素对四环素吸附的影响。结果表明：改性过程使玉米苞叶表面结构发生变化，显著提高了其对四环素的吸附量。在30℃，四环素溶液初始pH=5的条件下，吸附量为54.1 mg/g。在293~313 K的温度范围内，吸附量随温度的升高而升高，等温吸附曲线符合Freundlich模型；吸附过程符合伪二级动力学模型。
