Resuspend in one/twentieth the amount of contemporary routine maintenance broth, and increase an equal quantity of 20% (v/v in h2o) sterile glycerol. Cells developed on agar might be scraped through the floor into your ten% glycerol broth. Dispense small aliquots from the suspension into sterile vials.

Rather, bacterial growth in TSB is noticed to be a uniform turbidity or cloudiness through the broth.
Microbiologics on January 31, 2018 at 10:15 am Kathy – Typically, Growth Promotion Testing is done right about the agar plates and/or in the broth bags (or tubes) just before their use inside the laboratory.

dimaksudkan untuk kontrol positif apakah media benar-benar dapat ditumbuhi bakteri sesuai jumlah bakteri yang ditanam pada media tersebut, apabila dari media yang ditanam bakteri yang jumlahnya misalkan seventy five cfu dan ternyata jumlah bakteri yang tumbuh kurang dari fifty% dari jumlah bakteri yang ditanam dapat disimpulkan bahwa pengujian jumlah bakteri dan jamur pada sampel produk tidak legitimate karena media tidak dapat menumbuhkan bakteri sebagaimana mestinya.
