True and false :
Bioreactor provides the optimal conditions for obtaining desired product.

Answer

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement to evaluate is "Bioreactor provides the optimal conditions for obtaining desired product."

2. **Definition of a Bioreactor**: A bioreactor is a vessel or container in which biological reactions take place. It is designed to provide a controlled environment for the growth of microorganisms or cells.

3. **Optimal Conditions**: Optimal conditions refer to the ideal environmental factors that promote the growth and productivity of the organisms within the bioreactor. These factors include:
- Temperature
- pH levels
- Nutrient availability (substrates, salts, vitamins)
- Oxygen levels

4. **Function of a Bioreactor**: Bioreactors are engineered to maintain these optimal conditions consistently, which is crucial for maximizing the yield of the desired product, whether it be a metabolite, enzyme, or biomass.

5. **Conclusion**: Since bioreactors are specifically designed to create and maintain the optimal conditions necessary for the growth of microorganisms and the production of desired products, the statement is true.

**Final Answer**: True
