“…Besides, Cavalcanti et al . 43 emphasizing the adjunct of consortia composed by Pseudomonas aeruginosa and Burkholderia cepacia strains in the removal of phenanthrene and pyrene from a soil contaminated by a lubricating oil mixture containing PAH. In polluted soil the presence of Alphaproteobacteria , family as Bradyrhizobiaceae (slow-growing rhizobia), Rhizobiaceae , Nitrobacter and Sphingobium , known in literature to do nodules on the roots of leguminous plants and fixing nitrogen, is important.…”

Native plant species were screened for their remediation potential for the removal of Polycyclic Aromatic Hydrocarbons (PAHs) contaminated soil of Bagnoli brownfield site (Southern Italy). Soils at this site contain all of the PAHs congeners at concentration levels well above the contamination threshold limits established by Italian environmental legislation for residential/recreational land use, which represent the remediation target. The concentration of 13 High Molecular Weight Polycyclic Aromatic Hydrocarbons in soil rhizosphere, plants roots and plants leaves was assessed in order to evaluate native plants suitability for a gentle remediation of the study area. Analysis of soil microorganisms are provides important knowledge about bioremediation approach. Alphaproteobacteria , Betaproteobacteria , Gammaproteobacteria are the main phyla of bacteria observed in polluted soil. Functional metagenomics showed changes in dioxygenases, laccase, protocatechuate, and benzoate-degrading enzyme genes. Indolacetic acid production, siderophores release, exopolysaccharides production and ammonia production are the key for the selection of the rhizosphere bacterial population. Our data demonstrated that the natural plant-bacteria partnership is the best strategy for the remediation of a PAHs-contaminated soil.

“…No study has focused on it as an opportunistic microbe. In all documents looked at as part of our internet research, P. aeruginosa was included as part of a diversity, without addressing its particular role as an obstacle in the process of removing toxic contaminants, as has been widely reported in the literature (BAIG et al, 2021;CAVALCANTI et al, 2019). Additionally, it should be noted that P. aeruginosa is recognized as a keystone species in the degradation processes of numerous chemical compounds in both soil and water (CENTLER et al, 2020).…”

Pseudomonas aeruginosa is a ubiquitous fluorescent, rod-shaped pseudomonad, with a high metabolic capacity, and potential for application in processes to remove recalcitrant compounds such as petroleum hydrocarbons (PHC) from the environment. The bacterium persists in sites with highly selective pressures such as those contaminated by PHC. One of the bacterium's strategies is to colonize biofilms which enhance its protection from toxic compounds and favor oil uptake. It is the most prevalent microbe at sites impacted by PHC owing to the use of aliphatic hydrocarbons to form biofilms and other metabolites crucial for the uptake and degradation of crude oil. P. aeruginosa could be useful in biofilm-mediated bioremediation; however, it has been poorly explored in the last ten years. This systematic study addresses recent research on the application of P. aeruginosa/pseudomonads biofilms in bioremediation The studies come from Asia and Africa and emphasized the formation of biofilm by P. aeruginosa and other pseudomonads as crucial elements in the detoxification process of the environment.

“…Oliveira et al (2019) [155] obtained between approximately 20 and 60 µg/mL of pyocyanin, studying different concentrations of beer malt bagasse. Additionally, Cavalcanti et al (2017) [156] observed production of pyocyanin in reactors containing peanut, cotton and sesame cakes during the removal of hydrocarbons by P. aeruginosa in the soil. This finding, attributed to pyocyanin, suggests a possible participation in the mechanisms used by the bacteria during the assimilation of recalcitrant compounds as sources of carbon and energy, possibly associated with the mechanisms of QS for the synthesis of biosurfactants and other tensioactive agents [147,157].…”

“…The use of pyocyanin-producing P. aeruginosa strains also finds frontiers in bioremediation, especially in the removal of hydrocarbons from petroleum [ 156 ]. The expression of pyocyanin may have contributed evolutionarily by the genetic adaptation of the bacteria to the degradation of the oil [ 174 ].…”

Pyocyanin was the first natural phenazine described. The molecule is synthesized by about 95% of the strains of Pseudomonas aeruginosa. From discovery up to now, pyocyanin has been characterised by a very rich and avant-garde history, which includes its use in antimicrobial therapy, even before the discovery of penicillin opened the era of antibiotic therapy, as well as its use in electric current generation. Exhibiting an exuberant blue colour and being easy to obtain, this pigment is the subject of the present review, aiming to narrate its history as well as to unveil its mechanisms and suggest new horizons for applications in different areas of engineering, biology and biotechnology.
