Summary

Damage and death of haemophilic bacteria by freezing may occur due to thermal shock, osmotic shock, high salt concentrations, and a change in pH of the suspension medium. The initial concentration of bacterial cells affects the viability of haemophilic microorganisms suspended in a 0.14 M sodium chloride solution. Single-step cooling to -196 deg C at a rate of 400 deg C/min using a beef-extract broth as cryopreservation medium appeared to be the most effective method of cryopreservation of haemophilic bacteria.
