Question

Identify the beneficial activities of bacteria.

• A. The digestion of cellulose in herbivores
• B. The production of antibiotics
• C. The decomposition of waste matter
• D. All of the above

Answer 1

The correct option is D All of the above

There are bacteria present in the body of cattles, ruminants and herbivores. These bacteria produce the enzyme cellulase which helps in the degradation of the cellulose and hemicellulose. The organisms helps in the digestion of cellulose obtained from the raw plants which are consumed by these animals.

Many species of bacteria are used for the production of antibiotics. Streptomyces is the genus of bacteria which is known to be the highest producer of antibiotics which act as antifungal, antibacterial and antiparasitic.

The bacteria which perform anaerobic fermentation are commonly used for the decomposition of the organic matter from the plants and animals. They convert the waste matter into biogas which is used as a fuel.

Thus, the correct answer is option D.
