Above is the universal formula. Adjust Ingredients according to any specific protocols if needed.
Preparation
Suspend 41.7 g of the medium into distilled water. Mix well and make up to 1000ml. Heat with continuous stirring and aliquot into tubes or flasks. Sterilise in the autoclave at 115°C for 30 minutes (the media with Sucrose may turn dark at over 115°C).
^ During preparation, avoid naked flames and do not mix the basal salt mixture with reducing substances vigorously.
Storage
Media powder is extremely hygroscopic and should be protected from atmospheric moisture. If possible, the unused powder should be stored in a sealed box with silica desiccant.
