Abstract

The mechanism formation of colonies and biofilms of bacteria and yeasts are studied always of great interest. The aim of the presented work was transmission and scanning electron microscopic analysis contacts between cells of bacteria and yeast in biomofilms on natural structures and inorganic surface, as a result of formation of close contacts between a cellular wall, a fringe, cross-pieces, symplasts and cells of Escherichia coli, Shigella flexnerii Salmonella of typhi, Salmonella typhimurium and also some probiotic lactic acid on nutritious agar surfaces. Intercellular contacts in yeast biomofilms on plates of zirconium were scanning electron micro-scopic visualized by Candida guilliermondii.
