Application

Xylose Disks are used to differentiate bacteria on the basis of carbohydrate fermentation abilities.

Biochem/physiol Actions

Xylose disks are used based on the principle that microorganisms can only ferment certain carbohydrates. The ability to cleave various carbohydrates depends on the type of enzymes they possess. This can be detected either by gas production (CO2) in liquid media or change in color of the pH indicator because of the acid production.

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。
