Preparation
- Make up to 1 litre with filtered natural seawater. Adjust pH to 8.0 with 1M NaOH or 1 M HCl prior to autoclaving. For agar add 15g per litre Bacteriological Agar. Autoclave at 15 psi for 15 minutes.
- This medium will provide nutrients for long lasting, dense cultures and can be used in liquid and agar forms.
- First make primary stocks of Cyanocobalamin and Biotin.
- Dispense any excess primary stocks into 1 ml aliquots and freeze.
