A good producer of citric acid is
Show Hint
Citric acid is a natural and organic compound that is found in many citrus fruits. It is a weak organic acid and is neither a mineral, nor a vitamin, but is best for the human body. For people who suffer from kidney stones, citric acid in the diet will be so beneficial.
- Saccharomyces
- Aspergillus
- Pseudomonas
- Clostridiun
The Correct Option is B
Solution and Explanation
A good producer of citric acid is Aspergillus niger (a fungus).
For the most part, the largest application of Aspergillus Niger is the major source of citric acid in a major way. This organism accounts for over 99% of global citric acid production. Clostridium produces butyric acid, Saccharomyces cerevisiae is used for bread baking fermenting mailed cereals and fruit juices to produce ethanol. Pseudomonas (a bacterium) is used in vitamin-B12 production.
Therefore, the correct answer is option B, Aspergillus.

Concepts Used:
Microbes in Human Welfare
There are several valuable microorganisms that are beneficial to humans in various manners such as:
In Household Products
- Fermentation of milk to produce yogurt.
- Milk cuddling to compose curd, cheese, and paneer.
In Industrial Products
- Production of beverages such as wine, beer, whiskey, brandy, or rum.
- Production of antibiotics such as Penicillin and other chemical substances to kill or retard the expansion of disease-causing microbes.
Fermented Beverages
- A fermentor is used to produce microbes on a large scale for industrial purposes.
- The brewer’s yeast (Saccharomyces cerevisiae) is used to make ethanol. At this time, the yeast ferments malted cereals and fruit juices.
Antibiotics
- The term antibiotic means “against life”. These materials can kill or destroy the growth of other microbes.
