Differentiate between old and modern Biotechnology. Describe the discovery of Louis Pasteur on fermentation.

Question

Ghissu Editorial · Accepted Answer

Old biotechnology used microbes and selective breeding empirically for food and drink, while modern biotechnology manipulates genes precisely through recombinant DNA and genome editing. Louis Pasteur proved, through his swan-neck flask experiments, that fermentation is caused by specific living microorganisms, often acting without air, founding microbiology.

**Introduction**

Biotechnology’s evolution from ancient fermentation to modern genetic engineering underpins India’s economic and scientific progress, with ==Andhra Pradesh== as a key player.

**Foundations and Institutional Development**

SKETCH: comparison | Old vs Modern Biotechnology  
a: Old Biotechnology  
b: Modern Biotechnology  
- Empirical use of natural microbes :: Molecular biology and genetic engineering  
- Natural, empirical methods :: Precise, technology-driven manipulation  
- Fermentation, selective breeding :: GM crops, recombinant proteins, gene editing  
- Traditional knowledge systems :: Research institutes, biotech parks  
- Variable quality and yield :: High precision and scalability

1. **Old Biotechnology Origins**: Traditional fermentation and selective breeding relied on natural microbial activity without understanding microbes.  
2. **Modern Biotechnology Emergence**: 20th-century advances like recombinant DNA and gene editing enable precise genetic manipulation, exemplified by SAATVIK chickpea approved by the Central Sub-committee on Crop Standards⟦1⟧.  
3. **Pasteur’s Institutional Legacy**: Louis Pasteur’s swan-neck flask experiment disproved spontaneous generation, establishing germ theory and microbiology.  
4. **Biotech Infrastructure in Andhra Pradesh**: ==Institutions like the Andhra Pradesh MedTech Zone in Visakhapatnam== and university biotech departments support research and innovation.

**Implementation Challenges and Outcomes**

1. **Old Biotechnology Limitations**: Traditional fermentation lacked control, limiting quality and scalability.  
2. **Modern Biotechnology Advancements**: Genetic engineering improves crop yields and vaccine production; genome-edited rice lines show promise.  
3. **Challenges in Adoption**: Low R&D spending (~0.65% GDP) and regulatory hurdles constrain growth, including in ==Andhra Pradesh==.

**Louis Pasteur’s Discovery on Fermentation**

1. **Disproving Spontaneous Generation**: Pasteur showed microbes in air cause fermentation, not spontaneous generation.  
2. **Swan-Neck Flask Experiment**: Demonstrated microbial growth only when exposed to airborne microbes.  
3. **Impact on Biotechnology**: Enabled controlled fermentation, foundational for industrial microbiology.  
4. **Living Agents of Fermentation**: Pasteur proved that living yeast causes alcoholic fermentation, that specific microbes give specific products, and that fermentation is 'life without air', leading to pasteurisation.

**Way Forward**

1. **Strengthen R&D Investment**: Boost funding in ==Andhra Pradesh== to enhance infrastructure and innovation.  
2. **Enhance Regulatory Frameworks**: Develop clear policies for GMOs to ensure safe adoption and public trust.

**Conclusion**

Building on Pasteur’s legacy and modern advances, India and ==Andhra Pradesh== can harness biotechnology for sustainable growth and innovation.
