“…After 12 days, most of the phenanthrene was located in the maize xylem (mostly bound to the walls), but it was not found in the spinach xylem. In soil, the symplastic uptake was also demonstrated to be the major entrance pathway of phenanthrene into wheat and of pyrene into Agropyron cristatum L. [61,62], whilst, in both cases, the apoplastic transport was also detected but at lower levels. The active absorption of contaminants involved H + transport and energy conversion processes, and the passive transport, was associated with water led/directed through protein channels; i.e., there was a stronger correlation between the PCB concentration in soil and in carrots than in potatoes, probably because the carrots presented oil channels that could be used for PCB transport [63].…”

“…However, in this case, the transport of contaminants into the plant interior is crucial for effective bioremediation [122]. In the last five years, there have been many publications dealing with different aspects of rhizoremediation, suggesting the maturity of this research field [62,[123][124][125][126][127][128][129][130][131]. As a result, a large number of different bacteria which are able to remove pollutants from soil have been described; Table 1 shows some examples of bacteria-plant combinations for the degradation of contaminants.…”

Plant-Bacteria Interactions for the Elimination of Atmospheric Contaminants in Cities

One of the major health risks for humans, especially for those living in large cities, is air pollution. Air pollution consists mainly of emissions of particulate matter (PM), nitrogen oxides, sulphur dioxide, ammonia and volatile organic compounds (VOCs). The organic carbon fraction of particulate matter is a mixture of hundreds of organic compounds, such as polycyclic aromatic hydrocarbons (PAHs), or polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), some of which are mutagenic and/or carcinogenic. Because this particulate matter represents a serious threat for human health, measures to reduce emissions and to eliminate contaminants need to be strongly reinforced, with a focus on novel biotechnologies. In this review, we will explore the possibilities that bacteria associated with plants may offer the amelioration of atmospheric contaminants in cities, and we will discuss this strategy in the context of “Green Architecture”.

“…Ornamental plants, landscape plants, bioenergy plants, and fast-growing plants are all possibilities for commercial usage. When organic pollutants are objectives for remediation, remediation solutions should be devised for both the organic pollutants parent and their metabolites, not simply the organic pollutants parent [148]. We should be aware of the fact that some organic pollutants' metabolites have a lengthy half-life or are even more harmful than the parent pollutants.…”

“…Meanwhile, further study is needed to understand the processes of plant-microbe, plant-plant, and microbe-microbe interactions under pollution stress. Soil contamination assessment techniques prior to remediation, as well as efficacy evaluation methods after remediation, should be more precise, integrated, intelligent, energy efficient, and quick [148].…”

Heavy metal contamination of the ecosystem remains one of the severe global threats. Even in trace quantities, heavy metals and metalloids such as chromium, lead, mercury, cadmium, nickel, and cobalt are toxic and carcinogenic, posing a serious threat to human life. Certain microbes and plants have evolved detoxifying pathways to fight the harmful effects of these inorganic metals, paving the door for bioremediation. Because of its environmentally benign nature, economic viability, and low labor and effort requirements, bioremediation outperforms other approaches in eliminating heavy metals. This review highlights the potential of microbes on remediation of heavy metals in the context of environmental protection and also focuses on the critical tolerance mechanisms used by these microbes in combating heavy metal contaminations. Furthermore, the bioremediation potential of bacteria, fungus, algae, plants, biosurfactants, biofilms and genetically altered microorganisms for the removal of these heavy metals was reviewed in this study. Applying these techniques as a sustainable environmental technology in the near future has shown synergistic benefits with a many-fold increase in the removal of heavy metals.
