It's to do with IM report rite?
Find out about the contents of the agar, and what S. aureus contains, and whether the enzymes it contains has any effect on the components of the agar, and u'll get your answer.

Google is your friend :)

I found the answer here :
Typical colonies of S.aureus on [Baird Parker] medium are 1-1.5mm diameter, with an opaque halo surrounded by a 2-5 mm zone of clearing. The halo is a result of lipase activity and the clearing zone is due to proteolytic action.
