Abstract

ABSTRACT With the emergence of multiple-drug-resistant pathogens, the antibacterial property of silver in colloidal form has emerged as a potential candidate for combating infectious diseases. A combination of antibacterial agents along with nanosilver could prove to be more potent due to broadened antibacterial spectrum with possibly lower doses. In the present study, a facile single-step green method of synthesizing silver nanoparticles functionalized with an antibacterial peptide from a food-grade lactic acid bacterium is reported. The synthesized enterocin-coated silver nanoparticles showed broad-spectrum inhibition against a battery of food-borne pathogenic bacteria without any detectable toxicity to red blood cells. The present results evince that a new category of biocide based on silver nanoparticles coated with food-grade antibacterials can be developed using simple methods.
细菌素包覆银纳米颗粒与食品病原体的相互作用及其抑菌效果
随着多重耐药病原体的出现,胶体银的抗菌特性已成为对抗传染病的潜在候选物。抗菌剂与纳米银的组合可能被证明更有效,因为抗菌谱更宽,剂量可能更低。在本研究中,报告了一种简单的单步绿色方法,合成了具有食品级乳酸菌抗菌肽功能化的纳米银。合成的肠球蛋白包覆银纳米颗粒对一系列食源性致病菌具有广谱抑制作用,对红细胞没有任何可检测到的毒性。目前的研究结果表明,可以用简单的方法开发出一种新型的基于银纳米粒子包被食品级抗菌药物的杀菌剂。
