Question

By the use of biotechnology in which of the following bacteria production of \[{B_2}\]vitamins has been increased to about 20,000 times?
A. Ashbya gossypii
B. E. coli
C. Pseudomonas denitrificans
D. Propionibacterium shermanii

Answer 1

Hint: Vitamin is a water-soluble vitamin that occurs naturally in some foods, at times added to others, and is available as a prescription medication and a dietary supplement.
Complete Step-by-step answer: B-complex is required for good eyesight, good health, cell health, proper brain and nerve functioning growth of red blood cells, hormone production, and a good appetite. B complexes comprise eight vitamins such as . Vitamin is also known as riboflavin, is one of eight B vitamins. All B vitamins help the body to convert food (carbohydrates) into fuel (glucose), which is used to generate energy. These B vitamins, often called B-complex vitamins, also help the body metabolize protein and fats.
Ashbya gossypii is a highly flavinogenic mold of the Saccharomycetaceae family that was widely exploited for the production of riboflavin (vitamin). Riboflavin (vitamin) is a water-soluble vitamin, which is produced by all plants and most microorganisms and is necessary for the development and reproduction of animals and humans. By the use of the fungus Ashbya gossypii, the production of the vitamin was increased by 20,000 times.
Therefore the correct answer is Option A.
Note:Ashbya gossypii is a filamentous fungus that is now exploited for the commercial production of riboflavin. The utilization of A. gossypii as a microbial biocatalyst is further supported by its ability to grow in less expensive feedstocks, low-cost downstream processing, and the availability of an easy-to-use molecular toolbox for genetic and genomic modifications.
