Given below are two statements (A-B) each with one or more blanks. Select the option which correctly.fills the blanks in the statements -
Statements :
A. Terramycin is an antibiotic isolated from ...............and interfere with the ...............of disease causing bacteria.
B. Microorganisms (e.g., bacteria, yeast, filamentous fungi, algae, etc) that can be cultured on a commercial scale in fermentor and used as a food source or as animal feed are called...................
Options:

Options

A. A- Amanita, protein synthesis, B - single coll protein (SCP)
B. A-Penicillium, protein synthesis, B - single cell protein (SCP)
C. A - Morchella, protein synthesis, B - single cell protein (SCP)
D. A-Streptomyces rimosus, protein synthesis, B - single cell protein

Answer

To solve the given statements, we need to fill in the blanks with the correct terms based on our knowledge of microbiology and the role of microorganisms in human welfare.

### Step-by-Step Solution:

1. **Analyzing Statement A**:
- The statement reads: "Terramycin is an antibiotic isolated from ...............and interfere with the ...............of disease causing bacteria."
- We know that Terramycin is an antibiotic that is derived from a specific type of bacteria. The correct term to fill in the first blank is "Streptomyces" (specifically, Streptomyces aureofaciens).
- The second blank refers to the action of the antibiotic. Terramycin interferes with the "protein synthesis" of disease-causing bacteria.

**Filled Statement A**: "Terramycin is an antibiotic isolated from **Streptomyces** and interferes with the **protein synthesis** of disease-causing bacteria."

2. **Analyzing Statement B**:
- The statement reads: "Microorganisms (e.g., bacteria, yeast, filamentous fungi, algae, etc) that can be cultured on a commercial scale in fermentor and used as a food source or as animal feed are called..................."
- The correct term to fill in this blank is "single cell protein" (SCP). These microorganisms are cultivated for their protein content and can be used as food or animal feed.

**Filled Statement B**: "Microorganisms (e.g., bacteria, yeast, filamentous fungi, algae, etc) that can be cultured on a commercial scale in fermentor and used as a food source or as animal feed are called **single cell protein**."

### Final Answer:
- A: "Terramycin is an antibiotic isolated from **Streptomyces** and interferes with the **protein synthesis** of disease-causing bacteria."
- B: "Microorganisms (e.g., bacteria, yeast, filamentous fungi, algae, etc) that can be cultured on a commercial scale in fermentor and used as a food source or as animal feed are called **single cell protein**."
