General description
Differential Reinforced Clostridial Broth is used to determine the count of sulfite-reducing bacteria by the MPN technique. The redox indicator resazurin is used to monitor anaerobiosis. Clostridia reduce sulfite to sulfide, which causes the culture medium to turn black. As other bacteria can also produce sulfide, vegetative forms must first be removed from the culture by a relevant treatment (e.g., pasteurization), and the anaerobic spore-forming microorganisms must then be identified. The addition of polymyxin (70 IU/ml) to the broth inhibits the growth of most non-spore-forming microorganisms.
Application
Differential reinforced clostridial broth is suitable for the enumeration of all clostridia by the MPN method in foodstuffs and other materials.
Features and Benefits
- GranuCult® offers superior granulated culture media
- Safe and sustainable due to reduced risks associated with fine dust and toxic substance inhalation, resulting in a safer work environment
- Excellent wettability, solubility, and free-flowing properties
- Convenient, with minimal component separation and clumping, even under warm or humid conditions
- High batch-to-batch reproducibility
- Prolonged shelf life of up to five years
- High number of test strains exceeding all regulatory demands
- Granulation technology allows many supplements to be included, with no need to add these separately
