Hint: Vitamin B2 is also called Riboflavin. Different microorganisms help in the production of different bioactive molecules like statins, cyclosporine, etc. A bioactive compound is a compound that affects a living organism, tissue, or cell, usually demonstrated by basic research in vitro or in vivo in the laboratory.
Complete step-by-step answer:
Vitamin B2 is obtained from Ashbya gossypi. It is a water-soluble vitamin. milk and dairy products are the main dietary sources of riboflavin. Because of its intense yellow colour, riboflavin is widely used as a food additive. In oxidoreduction reactions, Flavin coenzymes are electron carriers.
Roles of Riboflavin: Maintain the mucous membrane in the digestive system, maintains healthy liver, it also keeps eyes, muscle, and nerves healthy, Absorb folic acid, vitamin B1, B3 B6. Maintain hormone production by adrenal glands, and help in fetal development. Its deficiency occurs When the intestine does not absorb the vitamin. Its symptoms include inflammation of the tongue, mouth ulcers, red and cracked lips, and sour throat.
Acetobacter aceti produces acetic acid.
Aspergillus niger is a fungus that causes a disease called black mould and it is also used for waste management and biotransformations in addition to its industrial uses, such as the production of citric acid and extracellular enzymes.
Penicillium notatum now known as Penicillium chrysogenum produces the antibiotic penicillin.
Therefore, the correct answer is Option B.
Note: Riboflavin is a constituent of flavin mononucleotide(FMN) and flavin adenine dinucleotide(FAD) . After the addition of phosphate in riboflavin and FAD formed by the transfer of an AMP moiety from ATP to FMN, FMN is synthesized.
