KG Agar Base, 2.5KG

KG agar base is recommended for promoting fast and free sporulation to distinguish between Bacillus cereus and Bacillus thuringiensis. It is also recommended by APHA. Peptone and yeast extract in the medium supports the growth of B.cereus, B.thuringiensis. Lecithinase activity is observed as an opaque zone surrounding the individual colony. B.cereus is resistant to Polymyxin B, which restricts gram-negative organisms. B.cereus and B.thuringiensis can be distinguished by means of microscopic examination of stained cells. B.thuringiensis shows endotoxin crystals in sporulated cells. Application: For Laboratory Chemicals, Analytical Purpose, Biochemical Analysis Appearance: Light yellow to light pink homogeneous free flowing powder Gelling: Firm, comparable with 1.8% Agar gel Color and Clarity of prepared medium: Basal medium : Orange colored clear to slightly opalescent gel After addition of Egg Yolk Emulsion : Light orange colored opaque gel forms in Petri plates Reaction: Reaction of 1.95% w/v aqueous solution at 25°C. pH : 6.8±0.2 Cultural Response: Cultural characteristics observed with added sterile Egg Yolk Emulsion (FD045) and Polymyxin B Selective Supplement (FD003), after an incubation at 30-35°C for 24 hours
