取适量大肠杆菌菌种加入到 10 mL 样品瓶中，用无菌水稀释调配成 0

Take an appropriate amount of Escherichia coli strains into a 10 mL sample bottle, dilute with sterile water to prepare a 0.5 Mie turbidity standard bacterial suspension, take 50 μL of the bacterial suspension, and dilute it with a corresponding sterile medium 1000 times , Formulated into E. coli initial bacterial suspension. In the same way, prepare the initial bacterial suspension of other bacteria and fungi.

Take the appropriate amount of E. coli bacteria into the 10 mL sample bottle, with sterile water dilution and blend into 0.5 McSick than turbid standard bacteria suspension, take the bacteria suspension 50 sL, with the corresponding aseptic culture base dilution release 1000 times, with E. coli initial bacteria suspension. In the same way, the initial bacteriological suspension of other bacteria and fungi is formulated.
