大肠菌群系指-群在37℃、24小时能发酵乳糖、产酸、产气、需氧及兼性厌氧的革兰氏阴性无芽胞杆菌。常规检验大肠菌群的方法为三步法:初发酵试验、平扳分离和复发酵试验。时间需3-4天。对一些食品急需进行卫生监督有一定困难,如冷饮生产出厂不能存放,需马上销售。为简化检验方法,找出显易判定标准,缩短报告时间,今年夏季我们用 T、T、C显色法(氯化三
Coliform is the group of Gram-negative bacilli that ferment lactose, acid, gas, aerobes and facultative anaerobes at 37 ° C for 24 hours. Conventional test coliform bacteria method for the three-step method: the initial fermentation test, flat-plate separation and re-fermentation test. Time needs 3-4 days. For some food urgently needed for health supervision have some difficulties, such as cold drinks factory can not be stored, need to be sold immediately. In order to simplify the test method, find the easy decision criterion and shorten the report time, we use T, T, C colorimetric method this summer (chlorotris
