Using a new agar plate, lift the lid just enough to insert the loop. Streak the loop containing the bacteria at the top end of the agar plate moving in a zig-zag horizontal pattern until 1/3 of the plate is covered. Sterilize the loop again in the flame and cool it at the edge of the agar away from the bacteria in the plate that you just streaked.

The bacteria were isolated using pour plate method and identified based on their Analysmethod [1]: Räkning: Ingjutningsmetod med MSR agar (ISO 15214.

To prepare agar plates, just heat and pour into a sterile petri dish. Next, collect bacteria: Swab along any surface to test (your mouth, the bathroom counter, etc.). The eosin methylene blue agar (EMB agar) is a selective staining for gram-negative bacteria. It contains two dyes in the ratio of 6:1 and is both toxic to gram-positive microorganisms. It is both a selective and differential mediums for coliforms. Plate count agar (PCA) or Standard PCA is a bacteriological substrate used for determination of the total number of live, aerobic bacteria in a sample. Thus, PCA is not a selective medium.
