Q. Consider the following statements:
1.Precision Fermentation methods use live bacterial culture to make curd from milk.
2.Precision fermentation uses microbial hosts as “cell factories” for producing specific functional ingredients.
3.Precision fermentation is widely used to produce insulin in labs.
4.Food ingredients made using precision fermentation are cheaper.
How many of the above statements are correct?
Answer: B
Notes:
Explanation –
Statements 1 and 4 are incorrect. Traditional fermentation methods use live bacterial culture to make curd from milk. But precision fermentation teaches a microbe how to make a protein by using a genetic code—also known as the recombinant DNA technology. Currently, food ingredients made using precision fermentation are expensive.
Statements 2 and 3 are correct. Precision fermentation uses microbial hosts as “cell factories” for producing specific functional ingredients. Precision fermentation is widely used to produce insulin in labs.
