Single cell Protein(SCP), Introduction of SCP, Importance, types and Drawbacks of SCP, Types of Microorganism used for SCP, Applications of SCP
- 1. Presentation Topic- Single Cell Protein Presented By - Deepanshi M.Sc. Microbiology (1st Sem)
- 3. • "SINGLE CELL PROTEIN (SCP) refers to the dried cells of microorganisms (bacteria, yeasts, molds, algae, fungi) that are used as protein sources in human foods or animal feeds. • The term SCP was coined by Professor Carol L. Wilson at Massachusetts Institute of Technology (M.I.T.) in May, 1966. • SCP is not a pure protein, but refers to the whole cell of microorganism that also contains carbohydrates, lipids, nucleic acids, mineral salts and vitamins.
- 4. • It is an idea to solve global food scarcity . • SCP can give relief to the agriculture sector which uses large area for production of protein crops. • Production per unit area in the agriculture sector is low. • 10% of the World’s protein requirement can be met by SCP technology by using only one third of a square mile for SCP production. • Climatic factor affects agriculture, whereas SCP technology is not affected by climate .
- 5. Admirable features of microorganisms- • Rapid growth rate and productivity. • High protein content (soya beans have approximately 40% protein content) microbes Protein % Bacteria yeast filamentous fungi algae 50-80 45-55 30-55 45-65 • Process occupies a little land area. • Production is independent of seasonal variations. • Strain selection and further development are relatively straightforward.

- 8. •Substrate is the biomass on which the microorganism grow. Choice of substrate depends upon: • Ease of availability. • Oxygen requirement during fermentation. • Heat produced and the level of fermenter cooling required. • Downstream processing costs.
- 9. Potential substrates for SCP production For Algae carbon dioxide (CO2) and sunlight are the main source for growth of algae For Fungi sulfite waste liquor dairy waste, whey molasses lignocellulosic wastes For Bacteria agricultural, animal and food processing wastes methane, methanol etc. have also been used.
- 11. Cultivation methods The production of single cell protein takes place in fermentation. This is done by selected strains of microorganisms which are multiplied on suitable raw materials in technical cultivation process directed to the growth of the culture and the cell mass followed by separation processes. Two types of Fermentation • Submerged Fermentation 2. Semisolid Fermentation the substrate used for fermentation is always in liquid state which contains the nutrients needed for growth. , the preparation of the substrate is not cleared and it is also more used in solid state e.g. cassava waste.
- 13. · provides the best protein supplemented food for undernourished children Used in therapeutic and natural medicines for • controlling obesity • · lowers blood sugar level in diabetic patients • · reducing body weight, cholesterol and stress • · prevents accumulation of cholesterol in the body. Used in Cosmetics products for • maintaining healthy hair • · production of different herbal beauty products, like- Bio lipsticks, herbal face cream, etc.
- 14. Drawbacks of SCP • The concentration of nucleic acid is higher than other conventional protein sources and t is the characteristics of all rapidly growing organisms . • Microbial cell wall may be indigestible. • Single cell protein from algae may not be suitable for human consumption because they are rich in chlorophyll. • Skin reactions from consumption of foreign protein.
