When Acetobacter colonies form enough acetic acid from the ethanol, the calcium carbonate around the colonies dissolves, forming a very distinct clear zone. in order to isolate by using its fluoresecent keep a photographic plate so the we can know the position of the azotobacter in the plate using the immpression of its flourescence on the plate.
