| 中文摘要: |
| 随着水产养殖业的发展，由于抗生素滥用造成的环境污染和病原菌耐药性问题日趋严重，亟待开发一种抗生素的替代品加以解决。近年来，纳米银以其独特的优势被视作是一种新型的抗菌剂而受到普遍关注。本研究采用姜提取液生物合成纳米银，并将其与传统的化学还原法合成的纳米银相比较。合成的纳米银分别采用紫外-可见分光光度计、透射电子显微镜、X-射线晶体衍射仪和红外光谱仪进行了鉴定和表征，并对它们抑制6种典型的水产病原菌的抑菌活性进行了全面的分析。实验结果表明，姜提取物中的活性成分能象化学还原剂一样成功用于制备纳米银抑菌剂，并且生物合成的纳米银粒径更小，稳定性更高，并且对供试水产病原菌具有更显著的抑菌活性。因此，利用姜提取物生物合成纳米银将在水产领域中具有广阔的应用前景。 |
| 英文摘要: |
| With the development of aquaculture, there is an urgent demand for an alternative antibacterial agent to reduce the drug resistance and environmental pollution caused by the abuse of antibiotics. Recently, silver nanoparticles (AgNPs) have been viewed as a novel type of antimicrobial agents due to their unique advantages. In this study, AgNPs were biosynthesized with the ginger rhizomes extract. The biosynthesized AgNPs were characterised by UV-visible spectroscopy, transmission electron microscopy, X-ray diffraction and fourier transform infrared spectroscopy. Furthermore, the antimicrobial activities of the AgNPs were fully analyzed against six typical aquatic pathogens. The results indicated that the components in ginger extract could function as the chemical reductant to synthesize AgNPs. Moreover, compared with the AgNPs synthesized by chemical methods, the biosynthesized AgNPs were smaller, and had higher stability and antibacterial activity. Therefore, the biosynthesized AgNPs using ginger extract may have prospective applications in aquaculture. |
