Question
Find out the role of microbes in the following:
Single cell protein (SCP)
Solution
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. Some common bacteria utilised in the manufacture of SCP are listed below:
- Bacteria (such as Methylophilus and Brevibacterium)
- Cyanobacteria (such as Spirulina)
- Yeasts (Saccharomyces cerevisiae, Candida utilis, etc.)
- Filamentous fungi (such as Fusarium graminearum)
- Algae (including Chiarella)
There are various advantages of utilising SCP as food. Several of them are listed below:
- 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.

Read the passage given below carefully and answer the questions that follow:
|
The bacterium Bacillus thuringiensis serovar israelensis (Bti) is commercially prepared in various formulations such as liquid, water dispersible granules, powders, and pellets. It is used as a larvicide all over the world due to its ability to produce a toxic protein that primarily targets the larvae of mosquitoes. In Sweden, Bti has been applied on a large scale in the form of commercially available granular formulation Vecto Bac G (Valent BioScience, USA). The applications have taken place in the lower Dalalven River Area to control mass outbreaks of the floodplain mosquito Aedes sticticus. |
- Why does the toxic protein kill the insects but not the bacterium?
- Can the formulation Vecto Bac G be used to eliminate the species of mosquito referred to above? Why?
