Thank you is very helpfull, can you please give me way to understand how to not damage the agar with the loop?

[@garyekaiser]

Hi Lili,The key is to keep the entire loop wire almost parallel to the agar. If you hold the plate at eye level and lift the lid just enough to insert the wire it forces you to keep the loop at the proper angle for good streaking. If the plate is on the bench top and you lift the lid too high the tendency is to point the loop downward where it digs into the agar instead of gliding over the surface.
