Microbes not used extensively

Microbes are microorganisms that are very useful in various fields such as food, medicine, agriculture, etc. However, some microbes are not used extensively in certain fields.

The options given are:

I. Converting milk into curd
II. Making cheese of different flavor and taste
III. Production of anti-viral drugs
IV. Production of antibiotics
V. As bio-fertilizers
VI. Production of inorganic fertilizers

Out of these options, the answer is option C, which means that the microbes that are not used extensively are III (production of anti-viral drugs) and VI (production of inorganic fertilizers).

Explanation:

I. Converting milk into curd:

- The process of converting milk into curd involves the use of lactic acid bacteria such as Lactobacillus bulgaricus and Streptococcus thermophilus.
- These microbes ferment lactose (milk sugar) and produce lactic acid, which causes the milk protein to coagulate and form curd.
- This process is extensively used in the dairy industry to produce curd, yogurt, and other fermented milk products.

II. Making cheese of different flavor and taste:

- The process of making cheese involves the use of various microbes such as bacteria, yeast, and molds.
- These microbes ferment milk and produce different flavors and textures of cheese.
- This process is extensively used in the dairy industry to produce a wide range of cheese varieties.

III. Production of anti-viral drugs:

- Anti-viral drugs are used to treat viral infections such as HIV, hepatitis B and C, influenza, etc.
- The production of anti-viral drugs involves the use of various techniques such as cell culture, recombinant DNA technology, etc.
- Microbes such as bacteria and yeast are used in the production of some anti-viral drugs, but their use is not extensive.

IV. Production of antibiotics:

- Antibiotics are used to treat bacterial infections.
- The production of antibiotics involves the use of various microbes such as bacteria and fungi.
- These microbes produce antibiotics as secondary metabolites, which are then extracted and purified.
- The use of microbes in the production of antibiotics is extensively used in the pharmaceutical industry.

V. As bio-fertilizers:

- Bio-fertilizers are microorganisms that are used to enhance soil fertility and plant growth.
- These microorganisms fix atmospheric nitrogen, solubilize phosphorus, and produce growth-promoting substances.
- Bio-fertilizers are extensively used in agriculture to improve soil health and crop yield.

VI. Production of inorganic fertilizers:

- Inorganic fertilizers are chemical fertilizers that are produced by chemical reactions.
- Microbes are not extensively used in the production of inorganic fertilizers.

In conclusion, the microbes that are not used extensively are those involved in the production of anti-viral drugs and inorganic fertilizers.

Microbes are not used in production of antiviral drugs and production of inorganic fertilizers.  Although, microbes are used in converting milk into curd, antibiotic production, sewage treatment, bread and cheese industry etc.
