Abstract

The biofilm-forming pathogens with acquired antibiotic resistance and associated disease outbreaks are increasing worldwide, especially in the seafood industry. This study hypothesised that the bioengineered iron nanoparticles using the myrobalan (Terminalia chebula) extract (M-FeNPs) and its resin coating have an effective antibiofilm properties. 12 seafood waste-based biofilm-forming strains (SSS) were isolated from SS-316 metal coupon and screened for their antibiotic-resistant profile as per CLSI (2016) standards. M-FeNPs were characterised by UV, FTIR, etc. Over 50 % of SSS were resistant to Ciprofloxacin, Cefalexin and Penicillin-G. The antibiofilm activity of the M-FeNPs showed an excellent inhibition zone (16–24 mm), and the combination of M-FeNPs + Methicillin also showed better activity. in vitro antibiofilm study shows that upon adding M-FeNPs, biofilm formation was reduced from 1.425 g to 0.83 g at the end of the eighth day. The CLSM and SEM images indicated that the M-FeNPs are effective antibiofilm agents against biofilm strains.

探索生态良性防污剂在对抗海产品相关生物膜方面的作用：关于以 myrobalan 为媒介的 FeNPs 对生物膜 SS-316 金属螯合剂影响的体外研究

具有抗生素耐药性的生物膜病原体以及相关疾病的爆发在全球范围内日益增多，尤其是在海产品行业。本研究假设，使用茜草科植物茜草提取物（M-FeNPs）及其树脂涂层制成的生物工程铁纳米粒子具有有效的抗生物膜特性。根据 CLSI（2016 年）标准，从 SS-316 金属券中分离出了 12 种基于海鲜废物的生物膜形成菌株（SSS），并对其抗生素耐药性进行了筛选。通过紫外线、傅立叶变换红外光谱等对 M-FeNPs 进行了表征。超过 50% 的 SSS 对环丙沙星、头孢氨苄和青霉素-G 具有耐药性。体外抗生物膜研究表明，添加 M-FeNPs 后，生物膜的形成从第 8 天结束时的 1.425 克减少到 0.83 克。CLSM 和 SEM 图像表明，M-FeNPs 对生物膜菌株具有有效的抗生物膜作用。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
