NEET BIOLOGY

Detailed explanation-1: -Bioremediation is a process of detoxifying or degrading contaminants present in the soil, wastewater, or industrial sludge by biological means. Microorganisms (bacteria, fungi, etc.) can take part in this process, although plant-assisted bioremediation is often termed as phytoremediation (Ma et al., 2011).

Detailed explanation-2: -2.1 Definition of bioremediation Bioremediation is a process where biological organisms are used to remove or neutralize an environmental pollutant by metabolic process. The “biological” organisms include microscopic organisms, such as fungi, algae and bacteria, and the “remediation”-treating the situation.

Detailed explanation-3: -Bioremediation uses micro-organisms to reduce pollution through the biological degradation of pollutants into non-toxic substances. This can involve either aerobic or anaerobic micro-organisms that often use this breakdown as an energy source.

Detailed explanation-4: -Particular agents used for bioremediation are bacteria, fungi, and algae. Bacterially-mediated processes have been used to alleviate heavy metal toxicity. Endophytic bacteria have greater potential to tolerate and remediate heavy metals stress.

Detailed explanation-5: -Some examples of bioremediation technologies are bioventing, landfarming, bioreactor, composting, bioaugmentation, rhizofiltration, and biostimulation. Not all contaminants, however, are easily treated by bioremediation using microorganisms.
