Agro Fossil Free - Convoluted role of cyanobacteria as biofertilizer: an insight of sustainable agriculture

Descrizione generale

Accelerating population growth and depletion of natural energy/resources pose threats to environment as well as to long-term food and energy supply. The use of chemical fertilizers pollutes water and cause soil-erosion, infertility and impose alarming danger to the health of both beneficial microorganism and human. There is need for finding sustainable alternative for biomass production in the anthropocene. Cyanobacteria, a diverse group of prokaryotes are the most successful, the oldest life form on the planet. They play an important role in maintaining and building up soil fertility, increasing plant growth and yield as a natural biofertilizer, nutrient cycling, phosphorus bioavailability, N2-fixation, environmental protection, and also disease prevention. Cyanobacteria convert radiative energy into chemical energy. These biological systems generate oxygen through photosynthesis. These organisms provide food, energy, secondary metabolites, cosmetics, and medications. These high-value products can be made from biomass of cyanobacteria through environment-friendly large-scale cultivation while lowering CO2 levels-a green technology. The biofertilizer of cyanobacterial origin could be the replacement of the chemical fertilizer. The methods of preparation and role of cyanobacterial as biofertilizers for sustainable agriculture are focused in this paper.
