Abstract
Cyanobacteria also known as blue-green algae are primitive prokaryotic organisms capable of thriving in extremes of the environment, capable of oxygenic photosynthesis, and possessing the ability to fix atmospheric nitrogen into a biologically usable form. They have been area of research interest for a long time due to their potential of being exploited in multifarous sphere. Since long they have been recognised as excellent substitute for chemical fertilizer due to their ability to fix nitrogen, therefore, widely acknowledged as biofertilizers. They have been also found to be useful in bioremediation processes like other microbes and thus have been useful in the reclamation of usar land and in remediating various other pollutants either by bioaccumulating or degrading them. Apart from this, they have been useful in pest management as a biocontrol agent. Cyanobacteria alongwith methanotrophs are helpful in reducing the level of emission of greenhouse gases. Either by being free living or in association with other organisms in symbiosis, they are playing key role in the amelioration of various environmental concerns. This chapter is written to describe the diversity of cyanobacteria in the rhizosphere and utilization of cyanobacteria potential in various fields, thus making it an efficient, cost-effective, eco-friendly, and sustainable alternative for a better environment in the future.
