2. BLUE GREEN ALGAE (BGA)
Introduction- blue green algae also known as
cyanobacteria are a group of photosynthetic bacteria.
Blue green algae generally grow in lakes, ponds, and
slow-moving streams when the water is warm with
nutrients like phosphorus or nitrogen. Many different
species of BGA occur in Wisconsin waters, but the most
commonly detected include Anabaena sp. Microcystis
sp.
3. Systemic position
Spirulina is a blue green algae. It is recorded from water
logged rice fields, ponds, lakes, wastewater channels with
alkaline &saline soil
The algal multiplication occurs by fragmentation
Spirulina has been known for its protein 7 betacarotine
contents apart of a host of vitamins ,minerals ,pigments in
its make-uplt stands out among the algal forms with a protein
content
4. Culture
The commercial design of spirulina culture system
comprises a network 0f cement raceways with paddle
wheel agitation.
Culture medium depth 15-20 c ,light intensity 20-30k flux
pH 9-11 provided with nutrients.

7. Application of blue green Algae
It is a health food and nutritional supplement for the
human being has unlimited scope in the future.
BGA has been shown beatherapeutant with regard to
several maladies like night blinders, anemia, glaucomia
cholesterol accumulation.
Pigmentation of ornamental fishes and prone larvae has
commercial significance.
8. Its antioxidant properties have been attributed with cancer
prevention possibilities.
Spirulina with regard to human/ animal nutrition and
therapy command a high export value as also import
substitution.

10. Conclusion
Spirulina culture, in fact is being used as a tool to reduce
pollution from wastewater like domestic sewage.
Achieving the twin objectives of pollution reduction and
nutrient harvest in the form of a high quality proteins.
