MRS (ISO) Agar (DeMan, Rogosa and Sharpe), Oxoid Preparation:
Suspend 66.73g in 1 litre of distilled water. Boil to dissolve the medium completely. Dispense into tubes, bottles or flasks and sterilize by autoclaving at 121°C for 15 minutes. Selectivity can be altered by pH adjustment.
Storage conditions and Shelf life
Store the dehydrated medium at 10–30°C and use before the expiry date on the label.
Store the prepared plates at 2–8°C.
Sterilization of this medium in some autoclaves, at 121°C for 15 minutes, may cause the medium in some cases to fall outside the specified pH limit of 5.7 ± 0.1. Adjustment of the medium in these rare cases is recommended using acetic acid or sodium hydroxide.
