उत्तर
Single cell protein refers to micro-organisms (e.g., bacteria, yeast, filamentous fungi, algae) that can be commercially cultivated in a fermenter, processed in various ways, dried, or utilised as food or animal feed. The term SCP, however, is misleading because it implies that the protein is derived from a single cell. The biomass produced by unicellular and multicellular organisms is classified as SCP. The following list includes some common bacteria used in the production of SCP:
- Bacteria (such as Methylophilus and Brevibacterium)
- Cyanobacteria (such as Spirulina)
- Yeasts (Saccharomyces cerevisiae, Candida utilis, etc.)
- Filamentous fungi (such as Fusarium graminearum)
- Algae (including Chlorella)
There are various advantages of utilising SCP as food. The following list includes several of these advantages:
- SCP contains a lot of high-quality protein but very little fat.
- It can be manufactured in laboratories all year round, and its production is not climate-dependent.
- The micro-organisms used in SCP manufacturing grow quickly and create significant amounts of SCP from just a tiny area of land.
