Plants support a diverse array of bacteria, including parasites, mutualists, and commensals on and around their roots, these microbes have a profound influence on plant health and productivity. Biofilms are communities of microorganisms adhering to abiotic/biotic surfaces. This experiment was conducted in College of Agriculture, PJTSAU, Rajendranagar. There is a growing appreciation that the intensity of growth and yields of mung bean in the pot culture study are significantly influenced by the high persistency of adherent microbial populations (Biofilms). At the end of the experimental period, the invitro
pot culture study among the T1â€“T8 treatments, T4 (Trichoderma viridae + Bacillus subtilis + Pseudomonas fluorescence + Rhizobium leguminosarum
) treatment recorded the high activity in all the parameters at all the three plant growth stages due to high persistency of biofilms. Hence, the yield was recorded high in T4 treatment. The remaining treatments showed significant results in all the parameters. The response of biofilms (T1-T4 treatments) was more pronounced than that of coinoculation (T5-T8) and control. At different stages of crop growth the persistency of biofilms was checked under Scanning electron microscope. Positive responses such as plant growth hormone production, mineral nutrients solubilization, high enzyme activity in the soil and biocontrolling effects due to high persistency had contributed to the increased plant growth with Biofilms. These interactions between bacteria and fungi and their biodiversity had the effect on microbial ecology in soils of pot culture and therefore have the potential to sustain modern agriculture systems with the use of microbial community of biofilms as biofilmed biofertilizers.
