Ammonia, polypeptides, free amino acids, vitamins, and auxin-like substances are the main fixed form of nitrogen and are released by cellular secretion or by microbial degradation after the cell death (Subramanian and Sundaram, 1986). Energy and Nutrient Sources: They obtain nutrients from the water and energy from the sun. Cyanobacteria are relatives of the bacteria, not eukaryotes, and it is only the chloroplast in eukaryotic algae to which the cyanobacteria are related. Nitrogen-fixing ability is not only limited to heterocyst bacterial forms but also many nonheterocystous unicellular and filamentous genera are able to fix the atmospheric nitrogen.

Cyanobacteria definition, blue-green algae. All of the functions carried out in eukaryotes by these membrane-bound organelles are carried out in prokaryotes by the bacterial cell membrane. The shape of Cyanobacteria can range from spheroidal, rod-shaped, filamentous or tubular and move by secreting slime which facilitates their gliding movements across surfaces. Cyanobacteria and, hence, oxygenic photosynthesis evolved 2.7–2.2 billion years ago and had therefore ample time to diversify and adapt to newly evolving niches that emerged on Earth (Schopf et al., 2002; Blank, 2004; Tice and Lowe, 2004). Nitrogen fixer cyanobacteria from rice fields have been studied extensively. Generally, July and August in the Taihu lake basin is usually favorable to cyanobacteria outbreaks.

The name cyanobacteria comes from the color of the bacteria. Cyanobacteria blooms are most common in the summer when growth conditions are ideal but may occur at any time of year. One common pigment is phycocyanin, which is a blue color ('cyan' means dark blue). Blue-green algae can grow in lakes, ponds, reservoirs, and slow moving streams when environmental conditions are right, such as warm water, abundance of nutrients like phosphorus or nitrogen, and plenty of sunlight. Cyanobacteria play major role in soil nitrogen fixators in agricultural fields. Rice fields are fertilized by water fern Azolla which multiplies rapidly and contains the symbiotic blue-green alga Anabaena that fixes gaseous nitrogen (Box 25.1).
