Question

Which one of the following is commonly used for converting cellulose raw materials into glucose?

• A. Saccharomyces cerevisiae
• B. Acinetobacter radioresistens
• C. Trichoderma viride
• D. Bacillus amyloliquifaciens

Hint:

In industrial biotechnology, Trichoderma species are extensively used for cellulase production. These enzymes are crucial in the breakdown of cellulose, which is a major step in processes like biofuel production.

Answer 1

The Correct Option is C

Step 1: Understanding the process of cellulose conversion into glucose

Cellulose is a complex carbohydrate found in the cell walls of plants. In nature, cellulose is broken down into glucose by organisms that produce cellulase enzymes. The conversion of cellulose to glucose is an important process, especially in biofuel production.

Step 2: Reviewing the options

Let's go through the options to understand which organism is commonly used to convert cellulose into glucose:

• Saccharomyces cerevisiae: This is a species of yeast commonly used in baking and alcohol fermentation. It ferments sugars into ethanol, but it does not produce cellulase enzymes needed for converting cellulose to glucose.
• Acinetobacter radioresistens: This bacterium is known for its resistance to radiation, but it is not known for its ability to break down cellulose.
• Trichoderma viride: This is a fungus that produces cellulase enzymes, which are used to break down cellulose into glucose. Trichoderma species, including Trichoderma viride, are widely used in industrial applications for cellulase production, making them the correct answer.
• Bacillus amyloliquifaciens: This bacterium is known for producing amylase, which breaks down starch into sugars, but it does not produce cellulase to break down cellulose.

Step 3: Conclusion

The correct answer is Trichoderma viride, as it is the organism that produces cellulase and is widely used for converting cellulose raw materials into glucose.

Thus, the correct answer is \( \boxed{{\text{Trichoderma viride}}} \).
