一般說明
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.
應用
Deoxycholate Agar is a selective and differential plating medium for the isolation and differentiation of Gram-negative enteric bacteria.
特點和優勢
- 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

Edema factor (EF) and CyaA are adenylyl cyclase toxins secreted by pathogenic bacteria that cause anthrax and whooping cough, respectively. Using the structure of the catalytic site of EF, we screened a data base of commercially available, small molecular weight
文章
Shigella spp. are predominantly connected to humans and are rarely isolated from other animals, with the exception of primates.
Dehydrated culture media for cultivating Shigella come in granules that dissolve in water. Granulation of the media ensures homogenous distribution, which avoids clumping even in warm and humid conditions.
