Solution
The correct option is B 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.
