Chlorella vulgaris is a species of green microalga that is spherical in shape and 2-10 um in diameter. It contains high levels of chlorophyll A and B and can reproduce asexually. There are two main types of chlorophyll - chlorophyll A which appears greenish and is the primary photosynthetic pigment, and chlorophyll B which appears yellowish-green. Chlorella vulgaris has medical uses such as preventing cancer and boosting white blood cells, and can also act as a natural antibiotic against certain bacteria. It is commonly used as a dietary supplement, protein source, and for biomass and lipid production.

3. INTRODUCTION :
* Chlorella vulgaris is single-celled green
species.
* It is spherical shape.
* About 2 to 10 um in diameter.
* Highest chlorophyll content in all plants.
* The Chlorella contain the green photosynthetic
pigments chlorophyll A and B.
* Chlorella vulgaris is a species of green
microalga in the division chlorophyta . It mainly used as a
dietary supplement or protein rich food additive .

4. CLASSIFICATION :
DIVISION : Chlorophyta
CLASS : Trebouxiophyceae
ORDER : Chlorellales
FAMILY : Chlorellaceae
GENUS : Chlorella
SPECIES : Chlorella vulgaris

5. STRUCTURE :

6. * This is cub-shaped.
* Chloroplast and numerous starch grains.
* This genus can reproduce asexually by non
motile reproductive cells .
* Which can rupture through the mother cell.
* The rupture cells from a new colony of chlorella
cells.
* The irregular clumps.

7. TYPES :
They are two types of chlorophyll .
1. Chlorophyll – A
2.Chlorophyll – B
1.Chlorophyll – A :
* Chlorophyll A present in all the
photosynthetic organisms on earth, giving a bluish
green colour to those organisms.
* Chlorophyll A is the primary photosynthetic
pigment present in plants and algae.

9. * It is a greenish colour pigment , which is to capture
energy from sunlight and produce foods in photoautotrophs.
* In both photosystems, reaction centre consists of
chlorophyll A molecules.
2. Chlorophyll B :
* Chlorophyll B gives a yellowish green colour to
organisms.
* Chlorophyll B is an photosynthetic pigment present in
plants and green algae.

11. * It’s porphyrin ring contain one CHO group, which is not
present in chlorophyll A.
* These pigment molecules act as a light-harvesting
antenna of photosystems .
* Compared to chlorophyll A, chlorophyll B is less
abundant.
* Chlorophyll B is more soluble in polar solvents than the
Chlorophyll A .
* It primarily absorbs blue light.

12. METHODS :
1. Induction phase
2. Exponential phase
3. Phase of declining relative growth
4. Stationary phase
5. Death phase

13. MEDICAL USES :
* Chlorella is used for preventing cancer and
increased white blood cell levels.
* Chlorella is used to prevent low levels of iron
during pregnancy.
* Chlorella anti-inflammatory effects may help
manage respiratory conditions like asthma or chronic
obstructive pulmonary disease ( COPD).

14. NATURAL ANTIBIOTIC :
* Bacillus subtilis
* Pseudomonas aeruginosa
* Escherichia coli

15. APPLICATION :
* Biomass produce
* Synthesis of proteins and lipids
