General description

Tryptic Soy Agar is a general-purpose culture medium for the isolation and cultivation of fastidious and non-fastidious microorganisms or the maintenance of stock culture. It is a complex medium for the cultivation and isolation of a wide range of bacteria, yeasts, and molds. The formulation of the TSA medium contains a combination of casein and soy peptones supplying organic nitrogen, particularly amino acids, and longer-chained peptides. Sodium chloride maintains the osmotic equilibrium, and the natural sugars from soy peptone are the energy source.

Application

Tryptic Soy Agar is used for the pre-cultivation and enumeration (E. coli) by membrane filtration technique. It is suitable for the cultivation of both aerobic and anaerobic bacteria. Since it does not contain the X and V factors, it is suitable for the identification of Haemophilus sp. by adding X (Hemin) and V (DPN=NAD) factors strips.

Features and Benefits

NutriSelect® Plus are powdered culture media offering
  • Quality control with growth promotion test according to industry standards
  • Quality assurance acc. to ISO 9001
  • Cost-efficient powdered media

Preparation Note

Suspend 40 g of dehydrated media in 1 litre of purified filtered water. Sterilize at 121°C for 15 minutes. Cool to 45-50°C. Mix gently and dispense into sterile Petri dishes or sterile culture tubes.

Footnote

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.

Cronobacter spp. are frequently found on vegetables, meat, fermented bread, dairy and in baby food. Consumption of contaminated powdered infant formula milk can result in sepsis, infant meningitis and necrotizing enterocolitis.

Vibrios are motile, curved or comma-shaped bacilli and have a single polar flagella with sheet proteins. They are often found in open water, freshwater and saltwater.

Campylobacter grows only on complex media that have been amended with diverse essential amino acids and supplements. We offer a broad range of specific agars and broths for the detection, identification, and cultivation of Campylobacter.

Campylobacter spp. are regarded as the leading cause of bacterial gastroenteritis in humans worldwide.
