Embodiment 2
[0098] Pull out the test tube cotton plug near the alcohol lamp, pour 10ml of sterile water, and gently scrape the bacteria on the slope with a sterile inoculation needle to suspend the spores, then pour the spore suspension Put it into a sterilized triangular flask with several glass balls in advance, shake it for 5 minutes, filter the bacterial solution with sterilized gauze, put it in another sterilized triangular flask, and then make the required bacterial solution.
[0099] Melt the beef extract peptone agar medium, and when cooled to 45°C-50°C, quickly pour it into sterilized petri dishes together with 0.2ml of bacterial suspension under aseptic conditions, 15ml of medium in each dish, shake well and cool down solidification. Use a sterilized hole puncher (aperture 4mm) to make a hole, drop 1ml of the drug solution into the round hole, place it in a 28°C incubator for 2 days, and measure the two diameters of the inhibition zone with a vernier caliper according to the cro...
