[Sensitivity of Escherichia coli phages to the action of the physicochemical factors accompanying the process of cryopreservation].
A temperature shock, a change in the pH of the medium for conservation within the range of 4.0 to 10.0, and an increase of NaCl concentration up to 5 M do not inactivate Escherichia coli phages T3, T4 and phi X174. The hydrostatic pressure of 2 X 10(3) atm inactivates phages T4 and phi X174. The sensitivity of the phages to the pressure correlates with their survival rate after freezing.
