Or there is this used to germinat seeds?
Preparation of starch agar plates (to make 4-5 plates):
1. Boil 50 cm3 distilled water in a beaker.
2. Mix 1 g of soluble starch with a little cold distilled water.
3. Add the starch suspension to the boiling water, stirring continuously.
4. Mix 1 g of agar powder with a little cold distilled water.
5. Add this agar suspension to the boiling starch solution, stirring continuously.
6. Pour the starch agar solution into a conical flask and plug the top with cotton wool.
7. Sterilise the agar and the dishes at 121 °C for 15 minutes.
8. Allow all materials to cool a little.
9. Line the petri dishes up along the edge of the bench. Wearing heat-resistant gloves, remove
the cotton wool plug from the flask and quickly flame the top of the flask.
10. With minimal opening, pour the starch agar into the sterile petri dishes.
11. Allow the starch agar to set.
