For enumeration, identification and isolation of Bacillus cereus in food.
制备说明
Dissolve 43 g in 900 ml water. Sterilize by autoclaving at 121°C for 15 minutes and let cool to 45-50°C. Add 100 ml egg-yolk suspension (Cat. No. 17148) and 10 mg polymyxin B (Cat. No. 81334) or 2 vial/l Polymyxin B Selective Supplement (Cat. No. P9602) to the autoclaved solution.
附注

For the enumeration of vegetative cells and spores of Bacillus cereus in foods, a mannitol-egg yolk-phenol red-agar has been developed which exploits the failure of B. cereus to dissimilate mannitol, and the ability of most strains to produce phospholipase C.
Some Bacillus species are crucial for advancing our understanding of bacteria, while others can be harmful, acting as spoilage organisms or pathogens. Nevertheless, all these species are significant in biotechnological research.
