| Bacillus cereus | Mannitol-Yolk-Polymyxin B (MYP) | Which contains egg yolk and polymyxin B for selective growth and differentiation. |
| Polymyxin Egg Yolk Mannitol Bromothymol Blue (PEMBA) | Which provides enhanced visual distinction of B. cereus colonies through pH changes and lecithinase activity. |
| Commercial chromogenic media | Which allow for more specific identification through color-based enzyme activity detection. |
| Clostridium perfringens | Tryptose Sulfite Cycloserine (TSC) | Which enables the detection of sulfite-reducing colonies under anaerobic conditions. |
| Shahidi-Ferguson Perfringens (SFP) | Another sulfite-reducing medium that contains egg yolk for lecithinase differentiation. |
| Commercial chromogenic media | Which provide improved specificity by targeting C. perfringens-specific enzyme activity. |
| Staphylococcus aureus | Mannitol Salt Agar (MSA) | Which selects for Staphylococcus species and differentiates them based on mannitol fermentation. |
| Baird-parker (BP) agar | Which contains tellurite and egg yolk to detect coagulase-positive colonies. |
| Baird-parker agar supplemented with rabbit plasma fibrinogen (BP-RPF) | Which enhances the detection of coagulase activity. |
| Commercial chromogenic media | Are also widely used for rapid and specific identification. |
| Escherichia coli | Eosin Methylene Blue (EMB) | Are classic choices that differentiate E. coli based on lactose fermentation, with characteristic color changes. |
| MacConkey |
| β-Glucuronidase-based chromogenic media | Target a specific enzyme commonly produced by E. coli, allowing for precise identification through color reaction. |
| Dry film systems such as Petrifilmâ„¢ EC | Provide a convenient and standardized platform for the enumeration of E. coli and coliforms in food samples. |
