Bacillus thuringiensis (Bt) strains have been used for designing novel

Options

  1. Abio-metallurgical technique
  2. Bbio-mineralization processes
  3. Cbio-insecticidal plants
  4. Dbio-fertilizers

Correct answer

C. bio-insecticidal plants

Step-by-step solution

Bioinsecticides are those biological agents, which are used to control harmful insects. A bacterium, Bacillus thuringiensis is used for this purpose. Spores of this bacterium produce the insecticidal cry-protein. Therefore, spores, of this bacterium kill larvae of certain insects. The commercial preparations of B. thuringiensis contain a mixture of spores, cry-protein and an inert carrier.
