Abstract: The Studies on the adhesion behaviour of bacterial and algae and its ecological significance have been reviewed in this paper. All research indicated that the adhesion processes of bacterial and algae involved an instantaneous reversible Phase and a time-dependent irreversible phase. The adhesion behaviour is basically controled by physico-chemical and biological forces and influenced by various environmental factors. The adhesion behaviour of bacterial and algae has important in freshwater ecosystem and its ecological significance implication is discussed in detail in the end.
