Abstract

Cyanobacteria are the only Prokaryotes which perform oxygenic-photosynthesis, cosmopolitan in nature and adapted well in harsh condition of environment. It is being used in agriculture, food processing, biotechnology etc. from a long time due to its contents. Proteins, carbohydrates, mineral, vitamins present in it make it a nutritious food supplement and ability to fix dinitrogen make it useful for agricultural activities. Quick and short growth span is one of advantage which makes it more useful. Cyanobacteria is being used by research scholars in treating sodic soils and increasing soil productivity for different crops. It helps to replace the chemical fertilizers and hence contributes to reduce pollution and proved as a potential biofertilizer. In addition, it is being used in production of biofuels including biodiesel, methane, alkane, alcohol etc. Along with agricultural benefits its uses are mentioned in treatment of waste water, sewage too. Disease and Pest controlled is also a

Keywords

Conclusion

Cyanobacteria are photosynthetic bacteria, ubiquitous in nature and are only Prokaryotes which perform oxygenic-photosynthesis. Due to easy and economical cultivation practices in open and closed conditions too, a lot of research carried on cyanobacteria. Hundreds of research results in finding the true effects and benefits of cyanobacteria in real-life situations, if it be agriculture or pharmaceutical or industrial or any other. Approximately 200 species of are identified and recorded with their potentials and research works are going on to identify more if present and to find the best potentials of these cyanobacterial species. Their total efficiency is not discovered completely but it is proved as a potential food, fertilizer, biodegrading, soil treating and a disease controlling agent. It can fix the dinitrogen through specific mechanism and is eco-friendly. It provides N as well as growth promoters to enhance the plant growth hence providing double benefit and save a lot of effor
