1 We recommend that liquid media be made by autoclaving the Na2CO3 separately, otherwise the high pH will cause ammonia to be lost. When making media solidified with agar (20 g/l) the agar should also not be autoclaved with the Na2CO3 otherwise the agar will be hydrolysed. When mixing the ingredients for solid media cool all components to about 55°C otherwise hydrolysis of the agar may occur. |
