A method was proposed for improving preservation of ultrastructures of deep-sea microorganisms by using rapid-freeze freeze-substitution after glutaraldehyde fixation. This method produced clear high-resolution images of cells appearing in their natural state, close to the quality of images obtained by rapidly freezing freeze-substituted specimens of living cells. The method may be useful for observing any microorganism when rapid freezing of living samples is difficult and only glutaraldehyde fixation can be carried out.
