Principle and Interpretation
Pseudomonas HiVeg Agar is prepared by using HiVeg special peptone, which is free from BSE/TSE risks associated with animal based peptones. It is the modification of Pseudomonas Agar which is based on the formulation described by King et al (1) for detecting pyocyanin, a water soluble pigment by Pseudomonas species (2). This medium enhances the elaboration of pyocyanin but inhibits the formation of fluorescein pigment. The pyocyanin pigment diffuses from the colonies of Pseudomonas into the agar and shows blue colouration. Some Pseudomonas strains produce small amounts of fluorescein resulting in a blue-green colouration. HiVeg special peptone provides nitrogenous growth nutrients, carbon, sulphur and trace elements for Pseudomonas species. Potassium sulphate and magnesium chloride enhances the pyocyanin production and suppresses the fluorescein production. Glycerol acts as a source of energy and enhances pigment production.
Quality Control
Appearance of powder Light yellow coloured, may have slightly greenish tinge, homogeneous, free flowing powder.
Gelling Firm, comparable with 1.5% Agar gel.
Colour and Clarity Yellow coloured, clear to slightly opalescent gel forms in petri plates.
Reaction Reaction of 4.64% w/v aqueous solution (containing 1% v/v glycerol) is pH 7.0 ± 0.2 at 25°C.
Cultural Response
Cultural characteristics observed after an incubation at 35 - 37°C for 18 - 24 hours.
| Organisms (ATCC) | Inoculum | Growth | Colour of Medium |
