在“浇碟法”的基础上,采用“营养琼脂培养基”作半成品的细菌总数测定,可缩短测定周期,及时提供参考数据。“营养琼脂培养基”是上海市医学化验所按“肉汤琼脂”配方生产的生化试剂,有较大的实用价值。配制方便、洁净澄明,观察细菌较清晰。在同样环境(同一培养箱内),同等条件(37℃),半成品的细菌生长较TTC培养基快得多。一般在16hr可观察计数,并提供参考数据;24hr则将菌检计数发出报
On the basis of “pouring dish method”, adopting “nutrient agar medium” to measure the total number of bacteria in the semi-finished product can shorten the measurement period and provide reference data in time. “Nutrient agar medium” is a biochemical reagent produced by Shanghai Medical Laboratory according to the formula of “broth agar”, which has great practical value. Convenient preparation, clean and clear, observe the bacteria more clearly. In the same environment (in the same incubator), the bacterial growth of the semi-finished product was much faster than that of the TTC medium under the same conditions (37 ° C). Generally observed in 16hr count, and provide reference data; 24hr then the number of bacteria seized report
