Nowadays, necessity is shown up concerning modeling of certain ecological processes actually emerging in various biotops and hence step-by-step study of development of biofilms on solid surfaces (glass and plastic). To implement such kind of studies the light and luminescent microscopy are the most available and rather informative tools. The study used strains V.cholerae O1 and O139 serogroups with different genetic characteristics. The biofilms were developed on cover glass and/or plastic plates which were placed in bottles with tap autoclave water in vertical position in special device. The lifetime visualization of stages of development of biofilm was implemented using luminescent microscopy by coloring biofilm with solution of acridine yellow. The biofilms colored with Congo read and fuchsine were analyzed using light microscopy. The light and luminescent microscopy permit investigating biofilms in dynamics at various stages of development, to evaluate condition of its physiological functioning in quantitative and qualitative dimensions and to trace synthesis of exopolysaccharides in different serogroups of vibrios that has significance in prognosis of velocity of occurrence of biofilms on abiotic objects.
