Descripción general

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.

Aplicación

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.

Características y beneficios

NutriSelect® Plus are powdered culture media offering
  • Quality control with growth promotion test according to industry standards

Lactoferrin (LF) is a multifunctional protein that plays important physiological roles as one of the most concentrated proteins in many human and other mammalian fluids and tissues. In particular, LF provides antibacterial properties to human milk, saliva, and tear fluid.

Artículos

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.

Some Bacillus species are crucial for advancing our understanding of bacteria, while others can be harmful, acting as spoilage organisms or pathogens. Nevertheless, all these species are significant in biotechnological research.

Specific agars and broths support detection and cultivation of Campylobacter, requiring complex media with essential supplements.

Preguntas

  1. Hi everyone and good afternoon My question is about checking of PH of Media, in which conditions we should check PH of the medium before autoclaving or after autoclaving

    1 respuesta
    1. Autoclaving affects the pH of the dissolved medium, hence it is preferable to check the pH after autoclaving. pH should be checked at a temperature between 20-25°C. Adjustments can be made with HCl/NaOH if needed, while stirring.
