Zastosowanie

Uwaga dotycząca przygotowania

Suspend 41.5 g in 1 litre of distilled water and let it sock for 5 minutes. Bring to boil and distribute into plates or tubes. Sterilization at 121°C for 15 minutes is optional, but if the medium is to be used on the same day of preparation it need to be sterilized. No sterilization improves the recovery of the stressed microorganisms.

Przypis

The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
