Summary
When slowly dried up in their culture medium, bacteria show chondrioids (equivalents of mitochondria) which are entirely different from the nucleoïds (equivalents of nuclei). Observations are made in the electron microscope by means of the replica technique, or directly with the phase contrast microscope. The chondrioids contain the Formazan deposited by vital reduction of Tetrazol.
