概括
细菌纤维素 (BC) 有效地从水中去除激素17α-乙inylestradiol (EE2). 虽然添加了生物表面活性剂改善了对醇的去除,但它减少了BC.的EE2吸附.
科学领域:
- 环境科学 环境科学
- 生物技术是生物技术.
- 材料科学 材料科学 材料科学
背景情况:
- 药品污染水生环境,造成生态风险,因为它们在低度下具有毒性.
- 开发可持续的吸附材料对于从水中去除药品等新出现的污染物至关重要.
研究的目的:
- 评估细菌纤维素 (BC) 在水生系统中作为对甲醇和17α-乙烯乙二醇 (EE2) 的吸附剂.
- 研究一种集成微生物生物表面活性剂对BC对这些污染物的吸收能力的影响.
主要方法:
- 使用*Gluconacetobacter xylinus*培养了细菌纤维素膜.
- 从* Bacillus subtilis*合成了一个生物表面活性剂,并纳入BC膜.
- 使用受醇和EE2污染的水进行了吸附实验,并通过光谱测量和HPLC进行分析.
主要成果:
- BC对EE2的吸附能力高于对降醇的吸附能力.
- 生物活性剂的结合增强了对醇的吸收,但降低了EE2的吸附.
- 原始和冷干燥的BC与生物表面活性剂注入的BC相比,表现出优越的吸附性能.
结论:
- 细菌纤维素显示出在水生环境中修复EE2污染的巨大潜力.
- 需要进一步的研究来优化生物表面活性剂度,以便在不影响BC的有效性的情况下提高污染物去除率.

Bioremediation
18.4K
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.

Surface Membrane Barriers
1.1K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Factors Influencing Drug Absorption: Pharmaceutical Parameters
134
Solid dosage forms such as tablets and capsules undergo rigorous manufacturing processes to ensure stability and effectiveness. Their dissolution and absorption properties are influenced significantly by the choice of excipients (inactive ingredients that serve various roles in the formulation), and the methodology applied during production. The manufacturing parameters, such as compression force and granulation techniques, significantly affect dissolution rates. Elevated compression forces...
