Description

Standard Methods Caseinate HiVeg Agar is recommended for detection of proteolytic microorganisms. It has HiVeg protein as a major protein source for the proteolytic organisms. Proteolytic organisms form white or off white precipitate around the colony. Organisms which are strongly proteolytic can breakdown the precipitate formed around the colonies to soluble components with the formation of an inner transparent zone. For the enumeration of proteolytic psychrotropic bacteria, inoculated plates should be incubated for 10 days at 7°C. This medium is prepared by replacing animal peptones with vegetable defined peptones to avoid BSE/TSE/GMO risk.
