Directions
Suspend 20.5 grams in 1000 ml distilled water. Heat to boiling to dissolve the medium completely. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes. Mix well and dispense as desired.
Principle and Interpretation
Semisporulation Growth Agar is used for the growth and sporulation of Saccharomyces cerevisiae. Saccharomyces cerevisiae is a unicellular eukaryote that has become an important tool in microbial genetic techniques. It undergoes meiosis and sporulation which takes place in a single cell. Potassium acetate enhances the sporulation of diploid strains. This medium contains agar as the solidifying agent.
Quality Control
Appearance of Powder: Light yellow coloured, homogeneous, free flowing powder.
Gelling: Firm, comparable with 1.5% Agar gel.
Colour and Clarity: Light yellow coloured, clear to slightly opalescent gel forms in Petri plates.
Cultural Response:
- Cultural characteristics observed after an incubation at 35-37°C for 18 - 48 hours.
- Saccharomyces cerevisiae ATCC9763: good-luxuriant growth.
Storage and Shelf-life
Store below 30°C and the prepared medium at 2 - 8°C. Use before expiry date on the label.
