economic importance of anabaena

Genus: Anabaena. ECONOMIC IMPORTANCE OF BACTERIA Dr. Saji Mariam George Associate Professor, Assumption College Autonomous Changanacherry ... Anabaena azollae etc. Let’s figure out the economic importance of algae together! Economic Importance: Prokaryotic structure and asexual reproduction are the features of Cyanobacteria or blue-green algae. Some cyanobacteria, such as Anabaena, Lyngbya etc. Economic Importance. help in conservation of soil, thus checking soil erosion. The important genera of blue-green algae (Cyanophyceae) are Anabaena, Anacystis, Aphanizomenon, Gomphosphaeria and Oscillatoria. Economic Importance of Bacteria SMG 1. 1) Algae as food ... During the rainy season, the blue-green algae, notably species of Nostoc, Scytonema, Anabaena, and Aulosira, grow in large amounts. Contents 1. These generally give rise to grassy odours intensifying into piggy, almost septic, odours as the cells disintegrate. Cyanobacteria : General Characters & Economic Importance Reviewed by Rajkumar on October 28, 2017 Rating: 5 Introduction 2. Economic importance of Bacteria . ... Qscillatoria, Nostoc, Anabaena, Gleocapsa, Merismopedia, Cylindrospermum, Aulosira, Scytonema, Tolypothrix etc. An acidic chemical that is synthesized naturally by the cyanobacteria reduces the soil alkalinity. ... Anabaena azollae colonizes the floating water fern 8. Some spices of anabaena are endophytic and have within roots of circus and aquatic pteriodophyte azolla. 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. The corolloid roots of Cycas are good examples of this association. Members of Cyanophyceae such as nostoc, Anabaena, etc. (6) Few species of Anabaena and Aulosira are inoculated in ponds to check the development of mosquito larvae. Economic importance of cyanobacteria 2. can fix atmospheric nitrogen. Economic Importance of Algae in Agriculture. Anabaena Azollae is a small filamentous phototrophic cyanobacteria generally seen as a multicellular organism with two distinct, interdependent cell types. Cyanobacteria improve the fertility of the soil. Importance 3. These organisms are important for us because they fix nitrogen and increase the soil fertility. Algae biomass accumulates organic metals in soil. Economic importance of cyanobacteria 1. Cyanobacteria help in the reclamation of USAR soil. It prevents soil erosion. 3. Bacteria are both beneficial and Harmful. Economic importance of anabaena: Saxitoxins produced by anabaena can be used as a precursor to some other weapons or as biological weapons. 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. A brief account of the uses of algae is given below: (a) Algae Used as Food: The red, brown and […] -6 View Full Answer The beneficial activities of bacteria are given in Table 1.7. Apart from this, cyanobacteria also colonizes the roots of higher plants. Some algae can also produce toxic substances. Algae used as a fertilizer in soil to develop crops; (a) Biofertilizer. The economic importance of algae is very diverse. The important toxins producing cyanobacteria are Microcytic aeruginosa (= Anacystis cyanea), Anabaena flosaquae, Aphanizomenon flos-aquae. Spirulina is an edible cyanobacterium, which produces SCPs (single-cell protein). (2) The first is a small, circular, photoautotrophic “vegetative” cell that performs oxygenic photosynthesis and is typically blue green in color. can also fix free nitrogen of the atmosphere by means of heterocysts and thus increase fertility of the soil. ...
