For commercial and industrial production of citric acid, which one of the following microbes is used?
Show Hint
- Aspergillus niger
- Lactobacillus sp.
- Clostridium butyricum
- Saccharomyces cerevisiae
The Correct Option is A
Solution and Explanation
Step 2: Aspergillus niger, a filamentous fungus, is the most commonly used microbe for this purpose due to its ability to produce large amounts of citric acid under specific conditions.
Step 3: Other microbes like Lactobacillus, Clostridium, and Saccharomyces are used for different fermentation products, not citric acid.
Thus, Aspergillus niger is used for citric acid production.

The process of copying the genetic information from one strand of DNA into RNA is termed as transcription. The principle of complementarity of bases governs the process of transcription, also except that uracil comes in place of thymine.
Study the complete transcription unit given below and answer the following questions:
(a) Name the main enzyme involved in the process of transcription.
(b) Identify coding strand and template strand of DNA in the transcription unit.
Attempt either sub-part (c) or (d):
(c) Identify (C) and (D) in the diagram, mention their significance in the process of transcription.
OR
(d) Describe the location of (C) and (D) in the transcription unit.}
