说明
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
