- filter sterilize (0.2µm syringe filter), store in fridge (4°C)
- filter sterilize (0.2µm syringe filter), store in freezer (-20°C)
NB: Working Stock -> medium = 1ml/l
1° stocks : 50ml is enough to eventually make 50 000 litres of medium (i.e. you won’t need more than this)
PROTOCOL POUR PREPARER LE MILIEU DE CULTURE
1)Prendre 1 ml de chaque working solution de Major Nutrients (NaNO3, NH4Cl, KH2PO4, NaFeEDTA), les filtrer et les mettre dans un litre d' eau de mer stérile (A).
2)Prendre 37,22 g Na2EDTA.2H et le mettre dans 1 litre de MQ (1). Ajouter à ça 1 ml de chaque stock solution de metaux en trace ( ZnSO4.7H2O, CoSO4.7H2O, MnCl4.4H2O, H2SeO3, NiCl2.6H2O)→ la working solution des metaux en trace est prète (B).
3)Mettre 0.1 g de Thiamine.HCl dans 1L de MQ (2). Ajouter à ça 1 ml de chaque solution stock de vitamines ( B12 et Biotin)→la working solution des vitamines est prète (C).
4)Ajouter 1 ml de B et 1 ml de C aprés les avoir filtrées à A et le milieu est pret pour etre utilisé.
NATURAL SEAWATER MEDIUM PROTOCOL
1)Take 1 ml of every Major Nutrients' working solution (NaNO3, NH4Cl, KH2PO4, NaFeEDTA), filter sterilize and add to 1L sterile seawater (A).
2)Put 37, 22 g Na2EDTA.2H in 1L of MQ (1). Add to this 1 ml of every Trace metals' stock solutions ( ZnSO4.7H2O, CoSO4.7H2O, MnCl4.4H2O, H2SeO3, NiCl2.6H2O)→Trace metals' working solution is now ready (B).
3)Put 0.1 g Thiamine.HCl in 1L of MQ. Add to this 1ml of every Vitamins' stock solution (B12 and Biotin)→Vitamins' working solution is now ready (C).
4) Add to A 1ml of B and C after sterilized and natural medium is ready to use.
