产气荚膜梭菌特性及检测
产气荚膜梭菌会导致未煮熟或未正确消毒的罐头食品和水受到污染。了解如何检测、鉴定和区分这种病原体。
微生物学理论：培养基制备
微生物需要营养，营养是指微生物生长与繁殖所需的能量来源和特定环境条件。在自然环境中，微生物已经适应了最适合其需要的栖息地，然而在实验室中，这些要求必须通过培养基来满足。
弧菌检测
大多数弧菌采用葡萄糖等简单的 C 源作为能源，需要2-4％的NaCl或其他盐以及海水中存在的微量元素，即可实现最佳生长。有些物种可以使用多种能源。
EN ISO 11133和制备用水和微生物培养基性能测试
了解在采用EN ISO 11133集中纯化水和Milli-Q® IX纯水系统产出的纯水制备微生物培养基及进行性能测试时，如何比较两种水源。测试包括针对李斯特菌和沙门氏菌病原体的专用培养基。
