For the plant growth required Nutrients through the natural processes of nitrogen fixation, solubilizing phosphorus and stimulating plant growth through the synthesis of growth-promoting substances. Biofertilizer are produced form a wide variety of microbial cells such as Rhizobium, Azotobacter, Azospirillum, blue green algae and cynobacteria. In the present review the biofertilizer produced by Rhizobium of soil through biofilm forming bacteria. Microbial communities attached to surfaces, or Biofilms, are found in many environments. Including the soil this chapter describes the potential applications of developed Biofilms as biofertilizer in crop Production. Formation of fungal–bacterial biofilm (FBBs) by bacterial colonization on biotic fungal Surfaces gives the Biofilms enhanced metabolic activities compared to monocultures. Incorporation of a Nitrogen (N2)-fixing rhizobial strain to FBBs to form fungal–rhizobial Biofilms (FRBs) has been shown to improve potential biofilm applications in N-deficient settings and in the production of biofilmed inocula for biofertilizer and biocontrol in plants. Isolation of biofertilizer from rhizobacteria is very helpful to detect the activity against microorganisms. This indicates that the highest microbial effect may not be achieved by plant inoculation with the conventional inocula of effective microbes, but only by biofilmed inoculation.
