Modified Gorodkowa Agar
Intended Use
Recommended for promoting the sporulation of yeasts.
Composition
| Ingredients | Gms / Litre |
|---|---|
| Peptic digest of animal tissue | 10.000 |
| Dextrose | 1.000 |
| Sodium chloride | 5.000 |
| Agar | 20.000 |
Formula adjusted, standardized to suit performance parameters.
Directions
Suspend 36 grams in 1000 ml distilled water. Heat to boiling to dissolve the medium completely and sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes. Mix well and pour in sterile Petri plates.
Principle and Interpretation
The medium contains Peptic digest of animal tissue which provides nitrogen and other nutrients necessary to support bacterial growth. Dextrose is the source of carbohydrate. Monopotassium phosphate buffers the media. Magnesium sulphate is a source of divalent cations. Sodium chloride is an essential ion and helps in maintaining the osmotic balance of the medium. Agar is the solidifying agent.
Quality Control
