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.

5. 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.

6. 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.

7. 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.
