摘    要:本文的研究目的是探索稀土离子Nd^3+对金黄色葡萄球菌细胞壁结构的影响作用。采用透射电镜、氨基酸自动分析仪和红外光普法等检测手段,提出了Nd^3+可使金黄色葡萄球菌细胞壁的形态和结构发生改变;低于抑菌浓度的NdCl3对金黄色葡萄球菌细胞壁的古成具有促进作用:高浓度(指杀菌浓度和抑菌浓度)Nd^3+可断裂细胞壁中肽聚糖的大部分肽键和氢键,致使细胞壁中肽聚糖的交联网状结构被破坏。

关 键 词:稀土  金黄色葡萄球菌  细胞壁结构

Abstract:The aim of this research is to study the effect of neodymium ion on the cell wall structure of Staphyloccocus aruea using transmission electron microscope, amino acid analyzer, infrared absorption spectrometry (IR). Experimental results show that Nd3+ can change the shape and the structure of the cell wall of Staphyloccocus aruea NdCl3 with lower concentration than the bacteriostatic concentration can help to synthesize the cell wall structure of Staphyloccocus aruea. Nd3+ with higher concentration than the bacteriostatic concentration can break the peptide bond and the hydrogen bond so as to break the net structure in the peptideoglycan cell.
Keywords:The rare earth  Staphyloccocus aruea  The structure of the cell wall
