A seed-inventory strategy ought to be employed for extensive-phrase storage of cultures. Cultures been given with the ATCC ought to be resuscitated Based on Instructions. If developed in broth, the cells are pelleted by centrifugation. Resuspend in 1/twentieth the amount of refreshing routine maintenance broth, and include an equivalent volume of 20% (v/v in h2o) sterile glycerol. Cells developed on agar could be scraped from the floor into the 10% glycerol broth. Dispense smaller aliquots with the suspension into sterile vials. Shop the vials in liquid nitrogen or in the mechanical freezer at no more than 50
