I always have completely sealed agar plates before they go into the incubator.
Yet, while working at Uni have been told not to worry about sealing them.
They have Serratia marascens growing on them and other interesting things from a "wash hands" prac.
I have taken them out of the incubator and are now in the fridge awaiting classes on Wednesday and Thursday.
Should I insist that they don't touch them ( only can touch the sealed plates ) or what ?
Gosh...this sounds like a Dear Dorothy Dix letter !
