Question

Starter culture are useful and specific microbes for ?

• A. Removal of pests
• B. Biofertilizers
• C. Biodegradation in xenobiotics
• D. Sewage degradation

Answer 1

Answer: (D)

Sewage degradation

A starter culture is a microbiological culture which actually performs fermentation. These starters are formed using a specific cultivation medium and a specific mix of fungal and bacterial strains. Specific microorganisms may be required to biodegrade the organic contaminants present in sewage. Employment of single microorganisms may not suffice the purpose. A mixture of microorganisms may have a cumulative effect on increasing the biomass activity, growth efficiency and enzyme production. In addition, the products of one microorganism act as a substrate for the other.

Therefore, the correct answer is option D.
