Majority of industrial enzymes are produces from :

Options

A. Gram-positive bacteria
B. Gram-negative bacteria
C. mycoplasma
D. algae

Answer

**Step-by-Step Solution:**

1. **Understanding the Options**: The question asks about the source of the majority of industrial enzymes, and the options provided are gram-positive bacteria, gram-negative bacteria, mycoplasma, and algae.

2. **Analyzing Algae**: Algae are simple organisms capable of photosynthesis, producing oxygen but not known for producing industrial enzymes. Thus, we can eliminate algae as an option.

3. **Analyzing Mycoplasma**: Mycoplasma are the simplest type of bacteria, often associated with diseases and lacking a cell wall. They do not produce industrial enzymes but are more related to pathogenicity. Therefore, mycoplasma can also be eliminated.

4. **Differentiating Between Gram-Positive and Gram-Negative Bacteria**:
- **Gram-Positive Bacteria**: These have a thick peptidoglycan layer and are widely used in industrial applications. For example, Lactobacillus is used in dairy for curd production, and other species of Bacillus are used as insecticides.
- **Gram-Negative Bacteria**: These have a thin peptidoglycan layer and are often associated with diseases (like typhoid and cholera). They are not primarily used for industrial enzyme production.

5. **Conclusion**: Based on the analysis, the majority of industrial enzymes are produced from gram-positive bacteria. Therefore, the correct answer is gram-positive bacteria.

**Final Answer**: Majority of industrial enzymes are produced from **gram-positive bacteria**.
