一般描述

Dextrose Discs are used to differentiate bacteria based on the dextrose fermentation ability. Microorganisms can only ferment certain carbohydrates, depending on the enzymes they possess to break down carbohydrates. Fermentation can be detected by gas production (CO2) in liquid media and/or color change of pH caused by acid production. The dextrose discs are aseptically added to any sugar-free basal media to test the ability of the organism to hydrolyze dextrose, a simple monosaccharide, as the sole source of carbon and energy during fermentation. Dextrose is typically fermented under acid production by many Enterobacter and coliform bacteria.

应用

Dextrose Discs are recommended to detect dextrose fermenting bacteria in food and environmental samples. They find their application in various sectors such as the food and dairy industry, water industry, pharmaceutical laboratory testing, cosmetic industry, environmental and sanitary testing, clinical diagnostic, etc.

还有许多其他检测方法来指示大肠杆菌的存在。查看这种污染物的常用检测方法和生化反应。

沙门氏菌污染是全球食源性疾病的第二大成因。控制沙门氏菌的暴发是食品监管机构、餐馆和整个食品工业的一项重要任务。沙门氏菌家族包括2300多种血清型的细菌,但其中有两种类型,即肠炎沙门氏菌和鼠伤寒沙门氏杆菌,约占所有人类感染的一半。大多数沙门氏菌的暴发可以追溯到乳制品、家禽和肉制品,但沙门氏菌几乎可以在任何食物上生长。鸡、鸡蛋及其衍生产品的风险特别高。
