Film-substrate potential, relative strength

E. Influence of Interfacial Films on Microbial Attachment. Air-water and solid-water interfaces accumulate surface-activeor hydrophobic organics present in the aqueous phase. Both the increased concentration of organic foodstuffs and the potentially increased adhesiveness of the interfacial film tend to increase the relative concentration of microbes at interfaces. In terms of cell immobilization, it may be possible to increase the strength of adhesion and the durability of the immobilized wholecell system by pre-coating the solid substrate with an appropriate interfacial film.
