There are two types of organisms which are used as inoculants: symbiotic organisms (such as Rhizobium, Synorhizobium, Bradyrhizobium, Nostoc, Anabaena, etc.) and non-symbiotic organisms (such as Azotobacter, Azospirilum, Beijerinckia, etc.) Spirogyra:- Spirogyra is a genus of filamentous green algae of the order  Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is diagnostic of the genus.
