Biology and Biotechnology of Environmental Stress Tolerance in Plants, Volume 3

Plants with high efficiency and rhizobacteria/genetically modified (GM)

microorganisms are thought to be preferable to expensive physiochemical

remediation approaches. The use of nematodes as an indication for stressed

environments produced by heavy metal pollution, on the other hand, appears

to be an added benefit in bioremediation systems. However, these biological

approaches reveal slow microbial metabolic growth kinetics. Degradation

of a complex combination of contaminants by a single species of microor­

ganism is also reported to be a time-consuming process. As a result, finding

microbial strains that can stimulate plant development while also degrading/

stabilizing contaminants is important, and future research should concentrate

on GM microorganisms for bioremediation and their mechanism of action

in successfully degrading pollutants. In addition, for successful pollution

remediation, the reaction model, degradation kinetics, and half-life period of

the degraded pollutants must be evaluated.
