Apart from this, cyanobacteria also colonizes the roots of higher plants. Algae used as a fertilizer in soil to develop crops; (a) Biofertilizer. (6) Few species of Anabaena and Aulosira are inoculated in ponds to check the development of mosquito larvae. These generally give rise to grassy odours intensifying into piggy, almost septic, odours as the cells disintegrate. Some algae can also produce toxic substances. Importance 3. ... Anabaena azollae colonizes the floating water fern 8. help in conservation of soil, thus checking soil erosion. The first is a small, circular, photoautotrophic “vegetative” cell that performs oxygenic photosynthesis and is typically blue green in color. Bacteria are both beneficial and Harmful. Economic Importance of Algae in Agriculture. It prevents soil erosion. Economic importance of Bacteria . (2) Members of Cyanophyceae such as nostoc, Anabaena, etc. ... Economic importance of genus Aspergillus. These organisms are important for us because they fix nitrogen and increase the soil fertility. The important toxins producing cyanobacteria are Microcytic aeruginosa (= Anacystis cyanea), Anabaena flosaquae, Aphanizomenon flos-aquae. The economic importance of algae is very diverse. 3. The corolloid roots of Cycas are good examples of this association. Introduction 2. Economic importance of anabaena: Saxitoxins produced by anabaena can be used as a precursor to some other weapons or as biological weapons. Some of the algae are used as food and fodder, in agriculture, industry, medicine, purification of water, aviation and as a source of petroleum and natural gas. can fix atmospheric nitrogen. Some spices of anabaena are endophytic and have within roots of circus and aquatic pteriodophyte azolla. Economic Importance. Economic importance of cyanobacteria 2. Anabaena is the filamentous form found occurring either in the single filament or as free-floating colonies or in a delicate means the stratum in permanent or semi- permanent form. 1) Algae as food ... During the rainy season, the blue-green algae, notably species of Nostoc, Scytonema, Anabaena, and Aulosira, grow in large amounts. Cyanobacteria help in the reclamation of USAR soil. -6 View Full Answer Some cyanobacteria, such as Anabaena, Lyngbya etc. Contents 1.
