Resuspend in one/20th the amount of new routine maintenance broth, and insert an equivalent quantity of twenty% (v/v in water) sterile glycerol. Cells developed on agar may be scraped with the floor into the 10% glycerol broth. Dispense tiny aliquots in the suspension into sterile vials. Retailer the vials in liquid nitrogen or inside of a mechanical freezer at no more than 50

You will find there's time-consuming method and A fast method. The time-consuming way consists of utilizing a spectrophotometer or turbidimeter to get the right concentration.

Lots of pharmaceutical companies use a daily “favourable Manage” wherein they inoculate Every media style employed with Trackbacks/Pingbacks

Growth acquired will have to not be differing by an element increased than two through the calculated value for standardized inoculums for Reliable Media, For freshly organized inoculums, growth of your micro-organisms comparable to that Formerly attained using a Formerly tested and accepted batch of medium happens.

–          Pada dasarnya pengujian Microbial Enumeration Test yang dilakukan pada media cair sama dengan media agar, perbedaan hanya pada pembacaan hasil inkubasi saja.
