食源性致病菌是人类健康的主要威胁之一。本研究旨在探讨壳聚糖(chitosan,Chi)协同姜黄素(curcumin,Cur)介导的光动力处理(photodynamic treatment,PDT)对致病菌的灭活效果。在确定Chi的最低抗菌剂量后,比较PDT和Chi-PDT的杀菌效果,进而评价Cur浓度和光照时间对Chi-PDT灭活金黄色葡萄球菌(Staphylococcus aureus)、蜡样芽孢杆菌(Bacillus cereus)、大肠杆菌(Escherichia coli O157:H7)和沙门氏菌(Salmonella Typhimurium)的影响。同时,探究Chi与PDT的协同作用机制以及Chi-PDT对混合致病菌的灭活作用、对圣女果表面Salmonella的灭活作用和对圣女果品质的影响。结果表明:Chi可以通过增强细菌与Cur的相互作用从而增强PDT灭活效果。Chi-PDT的灭菌效果具有Cur浓度和光照时间依赖性,0.05%(质量分数,下同)Chi结合15μmol/L Cur处理后光照20 min可分别使***和***的菌落总数减少7.90、7.60(lg(CFU/mL)),而对***和Salmonella则分别需要0.05%Chi-100μmol/L Cur和0.05%Chi-25μmol/L Cur处理后光照20 min才能达到相似的抑菌效果。Chi-PDT处理可使4种混合菌的菌落总数减少6.00(lg(CFU/mL)),比PDT单独处理时的抑菌量高5.09(lg(CFU/mL)),表明无论是对于单一菌还是混合菌,Chi-PDT协同作用都比PDT单独处理具有更好的灭菌效果。Chi-PDT可使圣女果表面Salmonella的菌落总数减少1.62(lg(CFU/果)),Chi-Cur涂膜协同PDT处理在圣女果保藏期间显示出了较好的抑菌效果,且不影响其色泽、硬度和质量损失率。因此,Chi-Cur协同PDT处理是食品杀菌和果蔬保藏领域中颇具潜力的食品保鲜技术。

An easy and effective solution based procedure for the synthesis of noble metal (both Au and Ag) tipped semiconductor nanomaterials is demonstrated where the metal precursors are taken in water and the semiconductors in organic medium, exploiting the phase transfer and reducing capability of suitably chosen ligands. The phase tranfer route is a generalised approach to form either Ag or Au tips on cadmium chalcogenide nanoparticles and nanorods. While multiple dots of noble metals are formed on the semiconductor nanomaterials initially, these coalesce into larger islands with time. The hybrids are characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), photoluminescence (PL), ultraviolet-visible spectroscopy (UV-vis) and X-ray photoelectron spectroscopy (XPS). A detailed FTIR analysis was also carried out to delineate the role of the ligands in the synthesis.

大肠埃希氏菌、金黄色葡萄球菌、沙门氏菌、溶藻弧菌、副溶血弧菌、铜绿假单胞菌、产气荚膜梭菌、单增李斯特菌和创伤弧菌是贝类食品中常见的食源性致病菌。该文通过设计特异性引物,优化反应参数以建立多重实时荧光串联PCR(multiplexed tandem PCR,MT-PCR)方法,进一步评估方法的特异性和灵敏度,并用于检测生蚝样品。优化后的MT-PCR方法与常规qPCR具有相同定量能力,可同时检测上述9种致病菌。在对混合菌液的检测中,MT-PCR方法的检测灵敏度最低可达10~2 CFU/mL,且此法对其中6种致病菌的检测灵敏度高于qPCR。应用该技术检测人工染菌的生蚝样品,检测灵敏度为10~2~10~3CFU/g。该研究建立的MT-PCR方法可实现高通量、快速准确地检测生蚝中这9种常见的食源性致病菌,对保障食品安全和评估食源性致病菌污染风险具有重要意义。
