उत्तर

Using microbes in the fermentation process allows you to produce various foods. Some major traditional recipes made with wheat, rice, and Bengal gram or black gram (vernacular urad) are as follows:

  1. Bread: Saccharomyces cerevisiae ferments wheat into this product.
  2. Dosa, upma and idli: They are fermented versions of rice and black gram (urad). The two are left to ferment for 3-12 hours with Leuconostoc and Streptococcus bacteria.

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.

  1. Why does the toxic protein kill the insects but not the bacterium?
  2. Can the formulation Vecto Bac G be used to eliminate the species of mosquito referred to above? Why?
