Single cell protein, single cell oil, and Quorn are produced from microorganisms. SCP is dried cells from algae, fungi, yeast or bacteria used as a protein supplement. Quorn is a mycoprotein produced from the fungus Fusarium venenatum as a meat substitute. Production involves growing the organism in fermenters, harvesting, processing, and drying the cells. SCP and Quorn provide protein, vitamins, minerals and are useful for addressing malnutrition. Single cell oil is extracted from microorganisms and can be used for food or cosmetics. These single cell products provide nutritional and therapeutic benefits.

3. INTRODUCTION AND HISTORY
• EARLIAR IT WAS KNOWN AS MICROBIAL
PROTIEN
• SINGLE CELL PROTIEN NAME WAS COINED BY
CAROL L WILSON
• YEAST IS RECOGNISED AS FIRST SINGLE CELL
PROTIEN
• PRUTEEN- FIRST COMMERCIALLY USED
PROTIEN PRODUCT
• FOOD FROM OIL TECHNOLOGY INTRODUCED
BY ALFRED CHAMPAGNAT AND LATER HE
AWARDED FOR THIS NOTABLE WORK

4. WHAT IS SINGLE CELL PROTIEN?
• Single Cell Protien are dried cells of microorganisms which can be
used as protein rich food supplements by humans and animals
• Microorganisms like algae,fungi,yeast and bacteria are used in the
production of scp

5. Sources of single
cell protein
A list of micro organism used for production of single cell protien
FUNGI
• Aspergillus niger
• Aspergillus fumigatus
• Rhizopus cyclopean
YEAST
• Saccharomyces cerevisiae
• Candida tropicalis
• Candida utilis

6. ALGAE
• Spirulina
• Chlorella pyronoidosa
• Chondrus cripus
BACTERIA
• Pseudomonus fluorescence
• Lactobacillus
• Bacillus megaterium

NUCLIC ACID 7-10 3-8 6-12 8-12

10. APPLICATIONS
As protein supplemented food
1. Also source of vitamins,amino acids ,minerals ,crude fibres etc
2. Supplemented food for undernourished children
3. As health food
4. Controls obesity
5. Provides instant energy
Ex spirulina past of us Olympic team

11. IN THERAPEUTIC AND NATURAL
MEDICINES
1. Reduces body weight, cholesterol stress etc
2. Lowers blood sugar level in diabetic patients
3. Prevents accumulation of cholesterol in body
4. Healthy eyes and skin
5. Beta carotene
6. Increases lactation

12. IN COSMETICS
• Important role in maintaining healthy hairs[ vit A and B]
• Many herbal beauty products
Biolipstics and herbal face cream
• Capable of replacing coal tar dye based cosmetics

13. QUORN
• It is a mycoprotein Produced by
fungi
• 0rganism used here is fusarium
venenatum
• It comprises enormous nutritional
value and low in saturated fat with
no cholesterol
• Substitute for meat products
• It was approved in 1983 for
commercial use

14. PRODUCTION OF QUORN

15. IMPORTANCE OF QUORN
• It a complete protein
• High in fibre
• Low in sodium ,sugar, cholesterol and fat
• Rich in essential amino acids

16. SINGLE CELL OIL
• Single cell oils are edible oil extracted from microorganisms
• Single celled entities are algae ,bacteria, yeast etc
• It is an intercellular product found in globules of some
microorganisms
• Most commonly used microorganisms are yeast and fungi
• Ex: saccharomyces rhodotorula Rhizopus mucor etc

17. General production

18. CONCLUSION
• The development of single cell protein is just a beginning in
biotechnology with the improvement in the production of scps we can
solve malnutrition conditions of progressive countries
