SUBMITTED BY: SWETHA U I M.Sc.Microbiology, Department of microbiology, Viaas,Sankari. DEPARTMENT OF MICROBIOLOGY

2. Introduction Microalgae are microscopic, photosynthetic organisms found in freshwater and marine environments. Unicellular or simple multicellular organisms.
Photosynthesis: Use sunlight, CO₂, and water to produce oxygen and biomass.
Nutrient Rich: High in proteins, lipids, vitamins, and antioxidants.

3. Why MICROALGAE matter Renewable and sustainable resource Rich in proteins, fats, pigments, and bioactive compounds
Used in multiple industries They grow quickly and require minimal space.

4. Categories of Value-Added Products Nutritional supplements Pharmaceuticals Cosmetics Biofuels Animal feed Agriculture Food & beverages Industrial applications

5. I Nutritional Supplements Protein sources Omega 3 fatty acids Vitamins and minerals

6. 1.PROTEINS FROM MICROALGAE Microalgae can contain 30- 70% protein of their dry weight depending on the species and cultivation conditions Some microalgae like Spirulina and Chlorella High quality protein and amino acids Uses in health supplements and protein powder

7. 2.OMEGA-3 FATTY ACIDS Schizochytrium and other algae DHA & EPA- support brain and heart health Alternative to fish oil supplements- Nannochloropsis Marine algae and phytoplankton are primary source for omega-3 fatty acids

8. 3.VITAMINS AND MINERALS Rich in vitamin B12,E and iron Supports the energy production, immunity and bone health Microalgae contain various minerals like magnesium, copper, manganese and potassium

9. II PHARMACEUTICALS Antioxidants- Chlorella,Spirulina(Arthrospira), Dunaliella, Haematococcus, and Porphyridium Anti inflammatory agents- Haematococcus pluvialis Antimicrobial and Antiviral compounds- Chlorella Immunomodulators- Porphyridium cruentum

10. Anti-inflammatory agents & antimicrobial and antiviral Treat chronic conditions Reduce inflammation-related diseases Improve recovery and pain management Algal extracts combat bacteria and viruses Supports treatment of infections Under research for advanced therapies
