Nutrients from plants are essential for the cultivation of crops and the production of healthy food to feed the worlds growing population. The impacts of global warming threaten nearly every economic sector, including agriculture. In order to maintain ecological equilibrium, microorganisms play an important role in the natural carbon, nitrogen, sulphur, and phosphorus cycles. Microbial biofilms are an intriguing issue because of their implications for ecology, economy, and human health. Advances in biochemical and molecular approaches have helped us gain a better grasp on how biofilms form and evolve. Growers are starting to take notice of biofilms because of their vast potential in agricultural productivity, security, and enhancement. Biofilms not only increase plant productivity, but they also play a critical role in the colonization of surfaces including soil, plant roots, and plant shoots. Utilizing bio-fertilizers allows plants to better absorb nutrients, thrive, and resist environmental stresses such as drought and pests. Potential biological fertilizers would be essential to the productivity and sustainability of soil, as well as to environmental conservation, because they are both environmentally beneficial and economical inputs for farmers.
