- A a mesh like structure formed by the association of bacteria and fungal filaments in sewage treatment.
- B the primary sludge produced in sewage treatment.
- C the effluent in primary treatment tank obtained during sewage treatment.
- D a type of biofortified food.
Answer & Solution
Correct Answer
(A) a mesh like structure formed by the association of bacteria and fungal filaments in sewage treatment.
Step-by-step Solution
Detailed explanation
(A) a mesh like structure formed by the association of bacteria and fungal filaments in sewage treatment.,
In sewage treatment plant during secondary treatment, a large number of aerobic heterotrophic microbes grow in the aeration tank that include bacteria and some filamentous fungi and yeasts which form flocs.Flocs are mesh like structure formed by interweaving of fungal filaments and bacterial cells.
