Question

What is Single cell protein?give advantages

Answer 1

Microorganisms have a high rate of multiplication to hence rapid succession of generation (algae: 2-6hours, yeast: 1-3 hours, bacteria: 0.5-2 hours)They can be easily genetically modified for varying the amino acid composition.A very high protein content 43-85 % in the dry mass.They can utilize a broad spectrum of raw materials as carbon sources, which include even waste products. Thus they help in the removal of pollutants also.Strains with high yield and good composition can be selected or produce relatively easily.Microbial biomass production occurs in continuous cultures and the quality is consistent since the growth is independent of seasonal and climatic variations.Land requirements is low and is ecologically beneficial.It is not dependent on climate

• Microorganisms have a high rate of

multiplication that means a large

quantity of biomass can be produced in a

comparatively short duration.

• The microbes can be easily genetically

modified to vary the amino acid

composition. They have high protein

contents- 43% to 85% (W/W basis).

• A broad variety of raw materials, including

waste materials, can be used as a substrate

for SCP. This also helps in decreasing the

number of pollutants.

• SCP serves as a good source of vitamins,

amino acids, minerals, crude fibres, etc.
