Attachment of soil bacteria to plant cells is supposedly the very early step required in plant–microbe interactions. Attachment also is an initial step for the formation of microbial biofilms on plant roots. For the rhizobia–legume symbiosis, various mechanisms and diverse surface molecules of both partners have been proposed to mediate in this process. A biofilm is an aggregate of microorganisms in which cells are stuck to each other and/or to biotic/abiotic surface. These adherent cells are frequently embedded within a self-produced matrix of Extracellular Polymeric Substance (EPS) is a polymeric jumble of DNA, proteins and polysaccharides. The high population density achieved in biofilms provides the opportunity to perform enhanced biochemical reactions than that of single isolates and dual cultures. In the present investigation we aimed towards the development of biofilms under in vitro conditions, using a combination of agriculturally important potential microorganisms like zinc solubilizing, potassium releasing bacteria on the fungal hyphosphere. All the isolates were screed for their zinc solubilization as well as potassium releasing capacity along with biochemical characterization. Biofilm formation of zinc solubilizing and potassium releasing isolates has considerably enhanced the release of potassium as well as zinc. Four hyphobacteria has exhibited high potential for solubilization of organic Zn to inorganic Zn as well as potassium (K) released considerably high when biofilm is used.
