Microbial biofouling is a problem of microbial biofilms slime on surfaces is the usual manifestation of a phenomenon called “biofouling”. It occurs in a wide range of industrial processes and in all of them it is a nuisance, sometimes a very expensive one. An example is the interference with heat exchangers, where both macro- and microfouling contribute to losses in heat transfer and to increases in fluid friction resistance. Biofilm formation is dependent on the surrounding environmental conditions and substratum parameters. Once a biofilm forms many factors may influence cell survival and resistance. Cell adhesion to a surface is a prerequisite for colonization. However, attached microorganisms may not be able to multiply, and may merely be surviving on the surface, for example, at a solid–air interface, rather than forming a biofilm. Retention of attached cells is a key focus in terms of surface hygiene and biofilm control. Factors that affect this retention may differ from those affecting biofilm formed on the solid-liquid interface: the nature of the substratum, presence of organic material, the vitality of the attached microorganism, and of course the surrounding environment. The majority of publications focus on the solid-liquid interface; literature addressing the solid-air interface is considerably less substantia.this paper reviews these effecting factors and Knowledge of management strategies to these factors as preventing surfaces from biofouling.
