If the outcome of GPT indicate failure, discard the whole large amount of geared up media and take into account each of the tests performed using that large amount as invalid
A seed-inventory method must be used for extended-expression storage of cultures. Cultures been given from your ATCC really should be resuscitated Based on directions. If grown in broth, the cells are pelleted by centrifugation. Resuspend in 1/20th the amount of contemporary servicing broth, and increase an equal quantity of twenty% (v/v in water) sterile glycerol. Cells developed on agar could possibly be scraped within the area in the ten% glycerol broth. Dispense compact aliquots on the suspension into sterile vials.
