Preparation
- 3:1 mixture
- See separate recipes. Autoclave separately. Mix aseptically when cool.
- Bring PJ (Mail sol. C 76) to the boil then add rye grass. Continue to boil for 5 minutes. Allow to cool then restore volume to 1 litre with deionized water. Filter through GF/C paper and autoclave at 15 psi for 15 minutes.
- Make up to 1 litre with deionized water. Autoclave at 15 psi for 15 minutes.
