This set of Environmental Biotechnology Multiple Choice Questions & Answers (MCQs) focuses on “Principle of Bacterial Degradation”.
1. ____________ process is the main pathway for degradation of bioorganic compounds.
a) catabolic
b) anabolic
c) catalytic
d) gluconeogenesis
View Answer
Explanation: Partial mineralization or decomposition of bioorganic or organic compounds is usually performed by Lower fungi, Bacteria, Yeast and algae but Mammals are not involved in the following decomposition processes in the environment.
2. Anabolic processes of microorganisms help in the decomposition of bioorganic or organic compounds.
a) True
b) False
View Answer
Explanation: Microorganisms like Lower fungi, Bacteria, Yeast and algae usually uses catabolic process that involves such pathways which help in the decomposition of bioorganic or organic compounds.
3. __________ of some xenobiotic can be traced back to a biological origin.
a) Carbon portion
b) Sugar portion
c) Potassium portion
d) Calcium portion
View Answer
Explanation: The carbon portion of some xenobiotic can be traced back to a biological origin to see if these substances were produced oil, natural gas or coal, sugar portion, potassium portion, calcium portion cannot be used to trace back the biological origin.
4. Which of the following return to the carbon cycle after incineration?
a) Coal
b) Oil
c) Natural gas
d) water
View Answer
Explanation: Coal, Oil, Natural gas can enter in to the atmospheric carbon dioxide cycle after incineration which is used for energy generation, water is not incinerated.
5. Stripping of carbon dioxide is necessary to prevent a drop in pH and _______
a) exhaust vapor condensate
b) fermentation
c) distillation
d) remove heat energy
View Answer
Explanation: The two process variants for oxygen supply differ in the stripping efficiency of carbon dioxide for respiration and the stripping of carbon dioxide is necessary to prevent a drop in pH and to remove heat energy.
