Product Description
Phenol Red Raffinose Broth is a specialized microbiology culture media designed to identify bacteria capable of fermenting raffinose, a trisaccharide sugar. The medium contains phenol red, a pH-sensitive dye that changes color (yellow for acid production, pink for alkaline conditions) to indicate fermentation activity. This makes it invaluable for differentiating bacterial species in clinical and research laboratories.
Commonly used in diagnostic microbiology, this broth helps isolate and study organisms like E. coli and Salmonella, which exhibit distinct fermentation patterns. Its simplicity and reliability make it a staple in educational labs, where students learn bacterial metabolism fundamentals.
