一般描述
GranuCult® plus Kanamycin esculin azide agar is a highly selective media for D-streptococci. Kanamycin and azide inhibit the accompanying bacterial flora. D-streptococci are, however, only slightly sensitive to these substances, so they grow normally and hydrolyze the glucoside esculin to give glucose and esculetin. Esculetin forms an olive-green to-black complex with iron (III) ions.
应用
GranuCult® plus Kanamycin esculin azide agar is suitable for the isolation, differentiation, and enumeration of enterococci in foodstuffs, water, and other materials.
特点和优势
- 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
