乳酸对粪肠球菌的抑菌作用及作用机制王凤婷;靳盼盼;刘芳;孙芝兰;吴海虹;王道营;许晓曦;徐为民【摘要】目前乳酸常被用来控制食品中腐败菌的生长,但是有关其对食品优势腐败菌抑菌机制方面的研究较少.本试验以一株从肉制品中分离得到的腐败菌粪肠球菌R612-Z1为目标菌株,研究乳酸对其的杀菌效果及作用机制.结果表明,各浓度(0.25%、0.50%、1.00%)的乳酸均有杀菌效果而且作用明显,通过激光共聚焦显微镜及流式细胞仪检测发现,处理后细胞膜通透性增强.扫描电镜及腺嘌呤核苷三磷酸(ATP)浓度的测定结果说明,胞内物质流出聚集在细胞外侧,胞外ATP浓度和核酸类物质浓度明显上升,膜电势快速升高.因此,乳酸通过破坏粪肠球菌的细胞壁,增加细胞膜通透性,改变细胞内外电势,导致内容物流出,从而达到杀菌效果.%Lactic acid(LA) is widely used to control the growth of contaminating bacteria in food,but there are few reports about the antibacterial mechanism of it. The antimicrobial activity of LA against a dominated spoilage bacterium, Enterococcus faecalis R612-Z1,isolated from water-boiled salted duck was studied. The results showed that all the selected concentrations of LA (0.25%,0.50%, 1.00%) had obvious bactericidal action. The permeability of cell membranes was increased for the bacterial cells treated with 1.00% LA, which was detected using the laser scanning confocal microscope and flow cytometry. The intracellular substances were leaked according to the results of scanning electron micrographs and the detection of extracellular ATP and UV-absorbing materials. The membrane potentials were found to be increased. There-fore,the antibacterial effect of LA on E. faecalis was mainly completed by the massive leakage of intracellular component,which was caused by damaging the cell membrane and membrane potential.【期刊名称】《江苏农业学报》【年(卷),期】2018(034)001【总页数】7页(P200-206)【关键词】粪肠球菌;乳酸;抑菌机理【作者】王凤婷;靳盼盼;刘芳;孙芝兰;吴海虹;王道营;许晓曦;徐为民【作者单位】江苏省农业科学院农产品加工研究所,江苏南京210014;东北农业大学食品学院,黑龙江哈尔滨150030;江苏省农业科学院农产品加工研究所,江苏南京210014;东北农业大学食品学院,黑龙江哈尔滨150030;江苏省农业科学院农产品加工研究所,江苏南京210014;江苏省农业科学院农产品加工研究所,江苏南京210014;江苏省农业科学院农产品加工研究所,江苏南京210014;江苏省农业科学院农产品加工研究所,江苏南京210014;东北农业大学食品学院,黑龙江哈尔滨150030;江苏省农业科学院农产品加工研究所,江苏南京210014【正文语种】中文【中图分类】TS201.3食品的安全、质量及营养价值是人们密切关注的问题[1]。

荧光共振能量转移(FRET)影像系统Olympus（北京）销售服务有限公司上海分公司PDF created with pdfFactory Pro trial version 荧光共振能量转移(FRET)影像系统一、研究目的随着生命科学研究的不断深入, 光学显微镜使我们理解了细胞结构和有关功能。

但是分子 生物学研究已经显示了分子事件，例如信号传导和基因翻译，需要蛋白质的装配成特殊的大 分子复合体等。

对各种生命现象发生的机制,特别是对细胞内蛋白质间相互作用的研究变得尤 为重要。

传统的生物物理或生物化学方法例如亲和色谱法或免疫沉淀反应法和近来的酵母双杂 交、磷酸化抗体、免疫荧光、放射性标记等方法等，都需要破碎细胞或对细胞造成损伤，无 法做到在活细胞生理条件下实时地对细胞内蛋白质-蛋白质间相互作用进行动态研究。

而基于强度的影像技术FRET方法，使得研究活细胞内的这些相互作用变得容易了，荧光 共振能量转移( FRET)是用于对生物大分子之间相互作用定性、定量检测的一种有效方法。

像原理
蔡司LSM900共聚焦显微镜的成像原理
共聚焦显微镜是指利用共聚焦显微成像技术（Confocal microscopy）作为技术基础，应用光学手段进行成像的一种光学显微镜。

共聚焦显微成像技术是一种利用逐点照明和空间针孔调制来去除样品非焦点平面的散射光的光学成像手段，相比于传统成像方法可以提高光学分辨率和视觉对比度。

共聚焦显微镜是一种利用逐点照明和空间针孔调至来去除样品非焦点平面的散射光成像技术的显微镜，是拥有高对比度和高分辨率的专业级显微镜。

常用语细胞及生物荧光样品观察分析；绿荧光蛋白分析；荧光复位杂交分析；光切片扫描以及
3D图像处理等应用中。

蔡司LSM900共聚焦显微镜的成像原理主要用于生物领域，共聚焦成像也被称为细胞CT。

能够获得焦平面细胞内一个层面的细胞图像，因无其它层面信号的干扰，能获得非常清晰的细胞图像。

共聚焦成像经过多年发张，如超分辨技术具有多种一样的实现方式相同，有多种方式能够实现共聚焦，不同的成像方式之间特点互补。

共焦成像是利用激光点扫描共焦成像的原理，即通过单个激光点激发样品中的荧光获得荧光信号，通过针孔屏蔽非焦平面信息，从而获得单片细胞图像。

在转盘可以聚焦的成像原理上，激光或普通激发光通过转盘变成多个激发点，转盘的旋转使激发光扫描整个样品，得到的荧光通过转盘的针孔去除非焦点细胞图像。

.b ž激光扫描共聚焦显微镜( LSCM) 是随着光学、视频、计算机等技术的迅速发展而诞生的一种高科技产品。

它是在荧光ž显微镜成像基础上加装了激光扫描装置, 利用计算机进行图像处理, 使用紫外或可见光激发荧光探针, 从而得到细胞或组织内部微细结构的荧光图像, 成为形态学﹑分子细胞生物学﹑神经科学﹑药理学﹑遗传学等领域新一代强有力的研究工具。

同时,激光扫描共聚焦显微镜也是活细胞的动态观察、多重免疫荧光标记和离子荧光标记观察的有力工具。

不仅可对活的或固定的细胞及组织进行无损伤的“光学切片”; 进行单标记或双标记细胞及组织标本的荧光定性定量分析; 还可用于活细胞生理信号, 离子含量的实时动态分析监测, 粘附细胞的分选, 细胞激光显微外科和光陷阱技术等。

可以无损伤的观察和分析细胞的三维空间结构。
