Who pioneered in the study of Philippine algae?
Dr. Velasquez
Profile: Dr. Velasquez pioneered in Philippine phycology. He made the first intensive study of the local Myxophyceae or the bluegreen algae and devoted at least 30 years of productive work in the study of Philippine algae from which he received local and international recognition.
What is the function of blue green algae answer?
Answer : Blue green algae fix the atmospheric nitrogen to enrich soil with nitrogen and hence, increase soil fertility.
Why is blue green algae important in rice cultivation?
Cyanobacteria play an important role in maintenance and build up of soil fertility, consequently increasing rice growth and yield as a natural biofertilizer [19]. Blue green algae (BGA) are photosynthetic nitrogen fixers and are free living. This process is called biological nitrogen fixation.
How do the Blue green algae help in improvement of agriculture?
They are important in agriculture as they can metabolize molecular nitrogen, solubilise insoluble phosphates, improve physical and chemical nature of soil and also add organic matter to the soil. 5. They also produce certain Plant Growth Regulators which has a positive effect on crop growth and crop yield.
What is the example of blue-green algae?
Examples of cyanobacteria: Nostoc, Oscillatoria, Spirulina, Microcystis, Anabaena.
What is present in blue-green algae?
Blue-green algae (cyanobacteria) are a group of prokaryotic, autotrophic microorganisms that contain the photosynthetic pigments (chlorophyll and phycocyanin).
What is the economic importance of blue green algae?
Blue green algae (BGA) possess immense morphological and metabolic diversity and can be used in economic development and environment management like wastewater treatment, land reclamation, production of fine chemicals, atmospheric fixation of nitrogen, production of methane fuel, conversion of solar energy, therapeutic …
What is the role of blue green algae and bacteria in fertility of soil?
They helps in replenishing the nutrients in the soil which are then taken in by the plants . They have the ability to fix the atmospheric nitrogen. Other bacteria such as Rhizobium also have the ability to fix atmospheric nitrogen.
Why cyanobacteria are used in field for improving soil quality?
More specifically, cyanobacteria fix nitrogen, which is an essential nutrient for supporting plant growth. The cyanobacteria tap the sun’s energy captured during photosynthesis to fix nitrogen from the air and turn it into a form which plants can use.
Which plant can be used as a Biofertilizer?
Biofertilizers today Rhizobium inoculant is used for leguminous crops. Azotobacter can be used with crops like wheat, maize, mustard, cotton, potato and other vegetable crops. Azospirillum inoculations are recommended mainly for sorghum, millets, maize, sugarcane and wheat.

Who is the leader of blue green algae in India?
The technical author of this manual, Dr. G.S. Venkataraman, is the Coordinator of the All India programme of blue-green algae and one of the foremost experts on the subject in Asia. The tremendous expansion and success of the technology in India is due largely to the dedication and activity of Dr. Venkataraman.
When was algae first used in the Philippines?
One of the early reports on the use of algae as food in the Philippines was in 1911 where about 11 marine algae or seaweeds were sighted being sold in Manila markets.
When is the best time to see blue green algae?
Warm weather helps BGA to grow, so you’re most likely to see it during the summer months. It usually occurs in still waters where there isn’t much flow, such as reservoirs and quieter canals. You might also see it when there hasn’t been any rain for a while. Why is it a problem?
