2. INTRODUCTION
• Microalgae are microscopic, photosynthetic organisms found in
freshwater and marine environments.
• Unicellular or simple multicellular organisms.
• Photosynthesis: Use sunlight, CO , and water to produce oxygen
₂
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

6. I NUTRITIONAL SUPPLEMENTS
• Protein sources
• Omega 3 fatty acids
• Vitamins and minerals

7. 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

8. 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

9. 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

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

12. 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

13. III COSMETICS
SKIN CARE PRODUCTS:
• Hydrates and repairs skin
• Reduces wrinkles and protects from
UV rays
• Used in creams, serums and masks
• Spirulina (blue green algae),
Chlorella,Ulva lactuca
ANTI-AGING COMPOUNDS
• Astaxanthin fights oxidative stress
• Supports skin elasticity and glow
• Popular in premium skincare
• Haematococcus pluvialis

14. III COSMETICS
HAIR CARE APPLICATION
• Improves hair strength, shine nourishes roots and
promotes growth
• Used in shampoos and oils
• Spirulina,Laminaria ,porphyra umbilicalis

16. IV BIOFUELS
• BIODIESEL PRODUCTION
• Oil extracted from algal biomass
• Processed into renewable diesel
• Chlorella, Scenedesmus, Spirulina and Dunaliella

18. IV BIOFUELS
• BIOETHANOL & BIOGAS
• Fermentation of algae to produce ethanol
• Anaerobic digestion creates methane-rich
biogas
• Sustainable alternatives to fossil fuels
• Chlorella, Chlamydomonas, and Ulva lactuca

19. V ANIMAL FEED
• Used in aquaculture and livestock diets
• Provides essential nutrients
• Improves growth, immunity, productivity
