TLDR
If phytoremediation is to become an effective and viable remedial strategy, there is a need to mitigate plant stress in contaminated soils, and there is also aneed to establish reliable monitoring methods and evaluation criteria for remediation in the field.About:

Journal ArticleDOI
Using soil bacteria to facilitate phytoremediation.
TL;DR: An overview of bacterially assisted phytoremediation is provided here for both organic and metallic contaminants, with the intent of providing some insight into how these bacteria aid phytorenmediation so that future field studies might be facilitated.

Bioremediation approaches for organic pollutants: a critical perspective
Mallavarapu Megharaj,Balasubramanian Ramakrishnan,Balasubramanian Ramakrishnan,Balasubramanian Ramakrishnan,Kadiyala Venkateswarlu,Kadiyala Venkateswarlu,Kadiyala Venkateswarlu,N. Sethunathan,Ravi Naidu,Ravi Naidu +9 more
TL;DR: This review selectively examines and provides a critical view on the knowledge gaps and limitations in field application strategies, approaches such as composting, electrobioremediation and microbe-assisted phytoremediating, and the use of probes and assays for monitoring and testing the efficacy of bioremediations of polluted sites.
Journal ArticleDOI
Current research trends on plastic pollution and ecological impacts on the soil ecosystem: A review
Yooeun Chae,Youn-Joo An +1 more
TL;DR: It is found that earthworms have been predominantly used as the test species in investigating the effects of soil plastic pollution on organisms, and further research investigatingThe effects of plastic on other species models (invertebrates, plants, microorganisms, and insects) are required to understand the effects on the overall soil ecosystem.

Phytoremediation: A Promising Approach for Revegetation of Heavy Metal-Polluted Land
An Yan,Yamin Wang,Swee Ngin Tan,Mohamed Lokman Mohd Yusof,Subhadip Ghosh,Subhadip Ghosh,Zhong Chen,Zhong Chen +7 more
TL;DR: The mechanisms of how heavy metals are taken up, translocated, and detoxified in plants are described and the strategies applied to improve the efficiency of phytostabilization and phytoextraction are focused on, including the application of genetic engineering, microbe-assisted and chelate-assisted approaches.
Journal ArticleDOI
Exploiting plant–microbe partnerships to improve biomass production and remediation
TL;DR: Because many bacteria show a natural capacity to cope with contaminants, they could be exploited to improve the efficiency of phytoremediation or to protect the food chain by reducing levels of agrochemicals in food crops.

Plant growth promoting rhizobacteria as biofertilizers
TL;DR: This review focuses on the known, the putative, and the speculative modes-of-action of PGPR, which include fixing N2, increasing the availability of nutrients in the rhizosphere, positively influencing root growth and morphology, and promoting other beneficial plant–microbe symbioses.
Journal ArticleDOI
Microbial degradation of hydrocarbons in the environment.
J G Leahy,Rita R. Colwell +1 more
TL;DR: Rates of biodegradation depend greatly on the composition, state, and concentration of the oil or hydrocarbons, with dispersion and emulsification enhancing rates in aquatic systems and absorption by soil particulates being the key feature of terrestrial ecosystems.
Journal ArticleDOI
Use of Plant Growth-Promoting Bacteria for Biocontrol of Plant Diseases: Principles, Mechanisms of Action, and Future Prospects
TL;DR: As agricultural production intensified over the past few decades, producers became more and more dependent on agrochemicals as a relatively reliable method of crop production.
Journal ArticleDOI
Microbial interactions and biocontrol in the rhizosphere
TL;DR: Multiple microbial interactions involving bacteria and fungi in the rhizosphere are shown to provide enhanced biocontrol in many cases in comparison with biocOntrol agents used singly.
Journal ArticleDOI
A Model For the Lowering of Plant Ethylene Concentrations by Plant Growth-promoting Bacteria
TL;DR: It is argued that the simplest explanation for the observed biological activity of plant growth promoting rhizobacteria relates to the relative amounts of 1-aminocyclopropane-1-carboxylate deaminase and 1-amino-2-car boxylate oxidase in the system under consideration.
