Observations of Microorganisms in Segregated Ice Using Methods of Electron Microscopy

摘要

Methods of optical and electron microscopy were used to find microorganisms in situ in the inclusions of segregated ice. The conditions of their viable preservation and the connection with the processes of ice formation are discussed. An experiment on the migration of microorganisms in the process of freezing of fine-grained soils was conducted. It is suggested that ice inclusions in frozen ground are the most suitable environment for the preservation and, perhaps, for the life of various forms of microorganisms.
