[Observation of the processes of low-temperature crystallization in an aqueous cell suspension by electron microscopy].

The possibility of using electron microscopy for the study of the processes of the low-temperature crystallization of water in cell suspension is discussed with E. coli M-17 culture used as an example. The replacement of water in the frozen state permits the observation of processes occurring in the sample at low temperature. The advantages of the method are demonstrated in the study of objects previously frozen at different rates.
