说明
一般描述
Deoxycholate agar contains peptone to provide nitrogen, vitamins, carbon, amino acids, and other nutrients to support the growth of microorganisms. Lactose is a fermentable carbohydrate. Sodium chloride and dipotassium phosphate maintain the osmotic balance. Sodium deoxycholate and ammonium iron citrate inhibit the growth of Gram-positive bacteria. Neutral red is a pH indicator. Agar acts as the solidifying agent.Fermentation of lactose is the basis for the differentiation of enteric bacteria. Lactose-positive bacteria, like coliform bacteria, produce acid from lactose and form red colonies. Lactose-negative bacteria, such as Salmonella spp. and Shigella spp., form colorless colonies.
应用
Deoxycholate Agar is a selective and differential plating medium for the isolation and differentiation of Gram-negative enteric bacteria.
特点和优势
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 allowing many supplements to be included, with no need to add these separately
附注
We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs.
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
