McClung Toabe HiVeg™ agar base is recommended for detection and isolation of Clostridium perfringens from food samples on the basis of their lecithinase and lipase activity. Lecithinase enzyme lyses egg yolk lecithin, producing an opaque zone of precipitation surrounding the slightly raised colonies. Positive lipase activity is indicated as an irridescent sheen on the growth surface. Clostridium perfringens show positive lecithinase and lipase negative activity. Clostridium sporogenes show positive lipase and lecithinase negative activity. Staphylococcus aureus are lecithinase and lipase positive. McClung Toabe HiVeg™ agar base is prepared by using vegetable peptones in place of animal based peptones which make the media free of BSE/TSE risks. Application: For Laboratory Chemicals, Analytical Purpose, Biochemical Analysis Appearance Cream to yellow homogeneous free flowing powder Gelling: Firm, comparable with 2.5% Agar gel Color and Clarity: Basal medium: Amber colored solution clear to slightly opalescent gel.After addition of egg yolk emlusion : Yellow colored opalescent gel forms in Petri plates Reaction: Reaction of 7.51% w/v aqueous solution at 25 deg C. pH : 7.6±0.2
