[Relationship between adsorption of microorganisms and the stage of their development]

Bond strength during adsorption of microorganisms depends on their growth stages, as was found by light optical and scanning electron microscopy. The strenth of adsorption often decreases as a culture growth on the surface of an adsorbent. Adsorption of microorganisms is an important ecological process. Under favourable conditions, microorganisms grow at a high rate when they are firmly bound to a solid surface. After abundant growth which deteriorates their microenvironment, microorganisms desorb and are dispersed. Such is a distribution of microorganisms growing on solid surfaces.
