a. STREAK PLATE METHOD: a. Pour melted NA or CWA, following aseptic technique in a petri dish and allow the agar to solidify. b. Sterilize the wire loop and get a loopfull of microorganisms of interest from the petri dish with mix culture done in the last activity. c. Streak very gently over the surface of the agar, taking care not to destroy it, as in figure below. DBS L Figure 1 Figure 2 d. Incubate the dish invertedly and examine the plate after 48 hours. e. Examine your previous petri dish further. Choose another colony and get a loopfull f. This time streak this in an agar slant. g. Incubate and examine tube after 48 hours.
