[Utilization of a method of growing microorganisms on millipore filters in order to study their structure with a scanning electron microscope].

A comparative study of bacteria and their L-forms Actinomyces and blue-green algae, taken from centrifugates and grown on Millipore filters, was made with the use of scanning electron microscopy. The study revealed that only in the second case the location of the cells inside the colony was preserved and the architectonics of the colony remained unchanged. The anastomoses between the cells and slime on the cell surface, destroyed when other methods of making the preparations were used, could be easily detected.
