What is pollutant biodegradation?
What is pollutant biodegradation?
Indeed, biodegradation is the process by which organic substances are broken down into smaller compounds by living microbial organisms [2]. In growth, an organic pollutant is used as sole source of carbon and energy. This process results in a complete degradation (mineralization) of organic pollutants.
What are the examples of biological degradation?
Factors affecting biodegradation rate
| Product | Time to Biodegrade |
|---|---|
| Disposable diapers | 50–100 years |
| Plastic bottle | 100 years |
| Aluminium cans | 200 years |
| Glass bottles | Undetermined |
Which of the following is an example of bioremediation?
The correct answer is D. The use of prokaryotes to treat sewage. An example of bioremediation is the use of prokaryotes to treat sewage….
What are non-biodegradable pollutants give example?
DDT, plastics, polythene, lead vapour, silver foils, etc. are non-biodegradable pollutants.
What is the difference between biodegradable and non-biodegradable pollutants?
Biodegradable pollution is those which are decomposed by natural biological agents. Non- biodegradable pollutants that do not decompose. They are decomposed and degraded by microbes. While non-biodegradable pollutants take a longer time to decompose.
What is resistant microbial degradation?
Some polymers are resistant to biological degradation because their carbon linkages cannot be broken from enzymes and microorganisms. The hydrophobic character limits further the enzyme activity together with other factors like low surface area, high molecular weight and crystallinity.
Which organism is useful in degrading organic pollutants?
Bacterium Pseudomonas is useful as it can.
Which of the following is non-biodegradable?
Examples of non-biodegradable wastes are plastics, glasses, metals, toxic chemicals, toxins, plastic products like plastic bags, grocery bags, plastic containers, and plastic water bottles are also non-biodegradable. So the answer is option D ‘Polythene’.
What do you mean by non-biodegradable material?
A Non-Biodegradable material can be defined as a type of material which cannot be broken down by natural organisms and serve as a source of pollution. Unlike biodegradable wastes, non-biodegradable wastes cannot be easily taken care of.
