Preparation
- Prepare 75% seawater from natural filtered seawater and deionized water.
- Bring 500 mL of 75% seawater to the boil and add cereal leaves.
- Continue to boil for 5 minutes.
- Cool and restore the extracted volume to 500 mL.
- Filter through GF/C paper and decant into the remaining 500 mL.
- Autoclave at 15 psi for 15 minutes.
