A Correct answer
Explanation

The extraction and processing of single cell protein is generally considered a costly process due to the need for large-scale bioreactors, downstream processing, and purification.

By using single-cell protein, amount of protein that can be produced by algae grown in ponds (per acre) is

  1. 20 tons

  2. 30 tons

  3. 40 tons

  4. 50 tons

A Correct answer
Explanation

A- Single-cell proteins (SCP) are produced by a range of microorganisms and substrate. They are dried cells of microorganism. When SCP is produced, the microbial products produce sufficient proteinaceous substances that can be utilized as protein supplements for animal feeds or human foods. It is estimated that algae grown in ponds can produce 20 tons (dry weight) of protein, per acre, per year.

D Correct answer
Explanation

Saccharomyces (yeast) is widely used for fermenting molasses into ethanol. Aspergillus is also used in industrial biotechnology for processing various substrates, making both valid contributors to industrial fermentation processes.

Which of the following is not employed in single cell protein production?

  1. Chlorella

  2. Aspergillus

  3. Clostridium

  4. Saccharomyces
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Single cell protein (SCP) production relies on microorganisms like algae (Chlorella, Spirulina), fungi (Aspergillus), and yeast (Saccharomyces). Clostridium is a genus of bacteria primarily known for anaerobic processes like nitrogen fixation or fermentation, not typically for high-yield SCP production.
