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