| 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 |
| 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. |
| 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. |
