Q. Consider the following statements regarding the commercial fermentation processes used for vitamin production:

P. The industrial yield of Vitamin B₂ (Riboflavin) in fungi such as Ashbya gossypii is significantly enhanced by utilizing lipid-rich media and bypassing purine-related feedback mechanisms.

Q. The production of Vitamin B₁₂ can be achieved using Pseudomonas denitrificans under strict anaerobic conditions or Propionibacterium freudenreichii under aerobic conditions.

R. The modern microbial production of Ascorbic Acid utilizes Ketogulonicigenium vulgare and has largely replaced traditional multi-step synthetic chemical routes.

S. D-Sorbitol and L-Sorbose are crucial intermediates in the purine and pentose phosphate pathways associated with Riboflavin synthesis.
