3. INTRODUCTION
Spirulina is a microscopic and filamentous cyanobacterium
that derives its name from the spiral or helical nature of its
filaments. It has a long history of use as food and it has been
reported that it has been used during the Aztec civilization.

4. HISTORY
• Spirulina was first discovered by Spanish Scientist
Hernando Cortez and Conquistadors in 1519.
• Spirulina appeared 3.5 billion years ago on earth,
spirulina is actually a cyanobacteria or” blue”
algae.
• With a size of 0.3 mm, it owes its name to its spiral
shape more or less constricted.

5. • It performed photosynthesis from particles of light, it
converts carbon dioxide into organic matter and releasing
oxygen.

6. DEFINITION
• Spirulina (Arthrospira platensis) is a filamentous and
multicellular blue-green alga capable of reducing inflammation
and also manifesting antioxidant effects.
• It has rich in protein, vitamins, minerals, carotenoids,and
antioxidants that can help protect cells from damage.
• Spirulina is a filamentous, tiny cyanobacterium with a
long history of use as a safe functional food.

7. CULTIVATION OF SPIRULINA
• The method of the cultivation and production is also safe and
hygienic.
• Spirulina has been proved to be a safe food through strict
toxicity tests by various research organizations.

9. PRODUCTION PROCESS
The production of spirulina consists four main processes,
1.Culture
2. Filtration
3.washing and dehydration
4.drying

10. CULTURE
• Spirulina is cultured under the same condition as its original
habitat, salt-water lakes, in subtropical area.
• An alkaline culture solution with nutrition is poured into a wide
shallow culture pond, which is stirred by gentle streams.
• This allows spirulina to efficiently carry out photosynthesis and
multiply itself.

11. FILTRATION
• Multiplied Spirulina is in the form of algae.
• It is then separated from the culture solution through filtration.

12. WASHING AND DEHYDRATION
Condensed spirulina which has been separated from the culture
medium is placed on vacuum dehydration filter and washed
repeatedly with clean water and dehydrated.

13. DRYING
The dehydrated spirulina is instantaneously dried with a spray
dryer and made into powder.

14. BENEFITS
1.Rich in many nutrients.
2.Boasts powerful antioxidant and anti-inflammatory properties.
3. May lower cholesterol and triglyceride levels.
4. Protects LDL cholesterol from oxidation.
5. May have anti-cancer properties.

15. 6. May reduce blood pressure.
7. Improves symptoms of allergic rhinitis.
8. Could be effective against anemia.
9. May improve muscle strength and endurance.
10. Could support blood sugar control.

• INTRODUCTON
• CHARACTERISTICS
• CLASSIFICATION
• CULTIVATION PROCESS

18. INTRODUCTION
• The genus Dunaliella belonging to Family Chlorophyceae includes
halotolerant, unicellular, motile green algae with exceptional
morphological and physiological properties.
• It is devoid of rigid cell wall & contains a single, large cup shaped
chloroplast.
• Dunaliella sp accumulate massive amount of B-carotene, primarily
in response to high light intensity.

19. UNIQUE CHARACTER OF DUNALIELLA
• Dunaliella salina is characterized by its ability to accumulate
very high concentrations of B-carotenel.
• Large quantities of Bcarotene so that the cells appear orange-
red extremely salt tolerant.
• Similar morphology to chlamydomonas.

21. Domain : Eukaryota
Kingdom : Viridiplantae
Phylum : Chlorophyta
Class : Chlorophyceae
Order :Chlamydomonadales
Family : Dunaliellaceae
Genus : Dunaliella
CLASSIFICATION

22. CULTIVATION OF DUNALIELLA
RAW MATERIAL :
Dunaliella can be cultivated in open raceway ponds with
simple requirements.
USE :
B-carotene rich Dunaliella as a source of the carotenoids,
which could be used in the food and health food
formulations.

23. PROCESS :
• Algal slants
• Conical flasks
• Carboy culture
• Outdoor tanks Cartoon genesis
• Harvesting
• B-carotene rich Biomass
• Drying
• Packing
