The non-selective agar is important to determine the CFU concentration from the inoculum. The brand new batch of liquid media is acceptable if:
– Pada dasarnya pengujian Microbial Enumeration Test yang dilakukan pada media cair sama dengan media agar, perbedaan hanya pada pembacaan hasil inkubasi saja. Kriteria keberterimaan pada media cair adalah dibandingkan tingkat kekeruhan pada media bets baru dengan media bets sebelumnya yang sudah lulus uji GPT.
Peptic digest of animal tissue and yeast extract serve as sources of carbon, nitrogen, nutritional vitamins together with other critical growth nutrients.
