Beneficial biofilms developed by nitrogen fixing bacteria and P - solubilising fungi in vitro conditions and also used as biofertilizers in non - leguminous crops and also observed that the bacteria colonized fungal mycelia to form biofilms. The biofilms showed high rates of biological nitrogen fixation and organic acid production which directly influences the synthesis of indole acetic acid like substances than microbes when used as monocultures.
