概括
微塑料 (MPs) 通过引起氧化应激和器官积累来伤害鱼类. 微封装的阿斯丁 (ASX) 有效地抵消斑马鱼的这些负面影响,为鱼类健康提供了一个有前途的解决方案.
科学领域:
- 水生物质毒理学研究
- 鱼类生理学 鱼类生理学
- 环境科学环境科学
背景情况:
- 饮食中的微塑料 (MP) 对鱼类构成威胁,转移到器官并诱导氧化应激.
- 对于鱼类中与MP相关的问题,迫切需要有效的缓解策略.
- 微封装阿斯丁 (ASX) 正在探索其降低MP毒性的潜力.
研究的目的:
- 评估微封装阿斯丁 (ASX) 在减轻微塑料 (MP) 诱导的氧化应激和斑马鱼 (Danio rerio) 积累中的疗效.
- 评估不同MP大小和度对斑马鱼健康的影响.
- 为了确定ASX是否可以恢复肠道完整性并减少MP转位.
主要方法:
- 斑马鱼在6个月的时间里被食不同大小 (1-5微米,40-47微米) 和度 (50或500毫克/公斤) 的MPs.
- 随后,鱼类被食了含有或不含微封装ASX (7g/kg) 的饮食,持续了另外一个月.
- 分析了对肠道上皮质,氧化应激标志物和器官中MP积累的影响.
主要成果:
- 微封装ASX抵消了小型和大型MP的负面影响.
- ASX恢复了由较大的MPs (40-47微米) 损坏的肠上皮.
- 对于较小的MP (1-5μm),ASX由于其抗氧化和凝固特性,减少了氧化应激和器官积累.
结论:
- 微封装的阿斯塔桑是一种有前途的食补充剂,可以减轻微塑料污染对鱼类的影响.

Biological Methods for Microbial Control
2
Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
