Abstract A novel method, laser interference microscopy, has been developed for studying the morphofunctional state of bacterial cells and the structure of bacterial communities. The following potentialities of the method are shown: rapid determination of the cell structure and subcellular structures (nucleus zone, vacuoles, lamellar structures) and the physiological state of the cell, as well as the study of the structure of bacterial communities (biofilm). The method does not require any additional preparation of cells before the investigation (fixation, staining, treatment with contrasting substances), which reduces the possible appearance of artifacts to a minimum and enables one to use laser interference microscopy for in vivo investigations.
