Bacillus thuringiensis (Bt) strains have been used for designing novel:
- Bio-metallurgical technique
- Bio-mineralization processes
- Bio-insecticidal plants
- Bio-fertilizers
The Correct Option is C
Solution and Explanation
Bt strains are well-known for their ability to produce proteins that are toxic to certain insect pests. These Bt proteins have been incorporated into genetically modified (GM) plants to create bio-insecticidal crops, often referred to as Bt crops. These plants produce their own insecticidal proteins, providing built-in protection against specific insect pests, reducing the need for chemical pesticides.
So, the correct option is (C): bio-insecticidal plants

Biotechnology
Biotechnology is a vast field of biology that involves the creation, production, and modification of useful products for human welfare using both the technology and the execution of living organisms and their components. An agricultural engineer, Karoly Ereky, coined the word "biotechnology" in 1919, achieving him the title of "Father of Biotechnology."
Principles of Biotechnology:
Among many, the two core techniques that entitled the birth of modern biotechnology are :
- Genetic Engineering is one of the methods of direct modifications of an organism's genome (i.e., DNA and RNA). It requires the introduction of new genes into host species to escalate function or trait, hence altering the host organism's phenotype.
- Bioprocess Engineering is one of the methods of maintaining sterile conditions to facilitate the growth of large quantities of desired microbes and other eukaryotic cells for the development of new or modified biotechnological products such as enzymes, vaccines, antibiotics, and other biotechnological products.
