sangat perlu dilakukan karena setiap bets media maupun setiap merek media yang berbeda terdapat perbedaan jumlah pertumbuhan mikroba, karena hal tersebut untuk menentukan media yang cocok maupun media yang masih layak pakai.
Cooling and storage: After sterilization, enable the TSB containers to chill to place temperature before making use of or storing them.
