Question

Which of the following microbes are a source of vitamin C
A) Pseudomonas sp.
B) Acetobacter sp.
C) Aspergillus sp.
D) Chlorella

Answer 1

Hint:- Vitamin C has the chemical name Ascorbic acid. Ascorbic acid is the natural form of vitamin C present in natural foods. Certain microorganisms are used to synthesize vitamin C for supplementation.

Complete answer:-
Pseudomonas doesn’t produce vitamin C. Rather, ascorbic acid acts synergistically with drugs acting against Pseudomonas.
The species, suboxydans of acetobacter is an important source of vitamin C. It contributes majorly to making commercial vitamin C supplements. It is a gram-negative bacteria. It also produces vinegar so it is also known as vinegar bacteria. It can also oxidize acetic acid to carbon dioxide.
Vitamin C is a water-soluble vitamin and can't be produced by the body on its own. So it has to be supplied from outside through supplement s. The water solubility is the reason why the human body can not overdose on vitamin C because it is excluded from the body along with water. Vitamin C also promotes the absorption of iron.
Aspergillus itself does not produce vitamin see but enhances vitamin C production. Aspergillus tamarii and Aspergillus flavus fused to form a hybrid cell. This hybrid cell promotes the production of vitamin C.
Chlorella is a source of iron. It is also known for Vitamin K and Vitamin B-complex, majorly vitamin B12.
Thus, the right option is B.

Note:- Chlorella and acetobacter are also being used For cancer treatment. This is a medicinal use of the microorganisms. Acetobacter is an acetic acid bacteria. Acetobacter aceti is the bacteria that is used for the economical production of vinegar. Acetobacter are found in fermented foods and beverages.
