________ चे उत्पादन जैवतंत्रज्ञानाचा सहायाने सहज व वाढीव प्रमाणात होऊ लागले.
(a) इथेनॉल
(b) अमिनो अॅसिडस्
(c) वाईन
(d) व्हिटामीन्स
पर्यायी उत्तरे :

The correct answer is Option D ((a), (b), (c), (d)).

Key Points:
• Core Concept
• Industrial biotechnology and microbial fermentation utilize genetically modified microorganisms and optimized bioreactor processes to synthesize valuable organic compounds at scale.
• Why Correct
• Modern biotechnology has revolutionized the production yields and purity of:
• 1. Ethanol: via recombinant yeasts (e.g., genetically engineered Saccharomyces cerevisiae).
• 2. Amino acids: produced in massive volumes using genetically enhanced Corynebacterium glutamicum (e.g., L-lysine, monosodium glutamate).
• 3. Wine: using improved yeast strains providing flavor consistency and stress resistance.
• 4. Vitamins: industrial fermentation yields vitamins like B₂ (Riboflavin) and B₁₂ (Cyanocobalamin) cheaply and cleanly.
• Key Details
• Genetic engineering and bioprocess control optimize metabolic pathways, eliminating feedback inhibition.
• Exam Traps
• Candidates may assume biotechnology applies only to pharmaceutical products, forgetting its widespread commercial use in biofuel, amino acid, and beverage production.
• Other Options
• Options 1, 2, and 3 omit one or more commercial biotechnology fermentation products. All four listed items are correct.
• Key Takeaway: Industrial biotechnology enhances the yield and quality of ethanol, amino acids, wine, and vitamins through fermentation.
