A common method is to place a spore mixture on the agar on one side of aPetri dish and streak it up and down that side until the spores are evenly spread along a line. The streaking is done with an inoculating wire having its tip bent into a loop so that it will not cut the surface of the medium.

- Organizing the work area to maximize work efficiency and avoid unnecessary movements will minimize the exposure time of experimental materials to airborne contaminants. Place the Bunsen burner to your right on the bench. Place agar plates or Petri dishes to your left.
