“…One notable attribute of the Burkholderia genus is their vigorous ability to degrade xenobiotic compounds and resistance to heavy metals [15], [17], [18], [19], [20], including U [21] and Ni [22]. Genome-centric assessment of strain SRS-W-2-2016 led to the identification of several gene homologues previously implicated in the resistance against heavy metal/radionuclides, such as the cobalt-zinc-cadmium efflux system, MFS transporters and permeases, outer membrane factor (OMF) lipoprotein, NodT family, multidrug efflux pumps, arsenite efflux membrane protein ArsB, and two-component system, OmpR family and copper resistance phosphate regulon response regulator CusR.…”

Savannah River Site (SRS), an approximately 800-km2 former nuclear weapons production facility located near Aiken, SC remains co-contaminated by heavy metals and radionuclides. To gain a better understanding on microbially-mediated bioremediation mechanisms, several bacterial strains resistant to high concentrations of Uranium (U) and Nickel (Ni) were isolated from the Steeds Pond soils located within the SRS site. One of the isolated strains, designated as strain SRS-W-2-2016, grew robustly on both U and Ni. To fully understand the arsenal of metabolic functions possessed by this strain, a draft whole genome sequence (WGS) was obtained, assembled, annotated and analyzed. Genome-centric evaluation revealed the isolate to belong to the Burkholderia genus with close affiliation to B. xenovorans LB400, an aggressive polychlorinated biphenyl-degrader. At a coverage of 90 ×, the genome of strain SRS-W-2-2016 consisted of 8,035,584 bases with a total number of 7071 putative genes assembling into 191 contigs with an N50 contig length of 134,675 bases. Several gene homologues coding for resistance to heavy metals/radionuclides were identified in strain SRS-W-2-2016, such as a suite of outer membrane efflux pump proteins similar to nickel/cobalt transporter regulators, peptide/nickel transport substrate and ATP-binding proteins, permease proteins, and a high-affinity nickel-transport protein. Also noteworthy were two separate gene fragments in strain SRS-W-2-2016 homologous to the spoT gene; recently correlated with bacterial tolerance to U. Additionally, a plethora of oxygenase genes were also identified in the isolate, potentially involved in the breakdown of organic compounds facilitating the strain's successful colonization and survival in the SRS co-contaminated soils. The WGS project of Burkholderia sp. strain SRS-W-2-2016 is available at DDBJ/ENA/GenBank under the accession #MSDV00000000.

“…The heavy metal removal process in soil was contributed to the adhesion of metal in soil mineral with strain Z-90 and helps in the formation of a metal complex with biosurfectant [8]. Several studies on amelioration of different metal ions by different hydrophytes have shown that the deposition of most metals content was higher in roots than in other plant parts [9,10].…”

Phytoremediation is an environment friendly and cost effective method for remediation of heavy metals from contaminated soils by using plants. Chelate assisted metal uptake by plant has only been discovered in the sector of phytoremediation. It is a potential technology for accumulation of heavy metal by plants after application of chelating agents to soil which enhances the level of metal uptake in phytoremediation processes. Chelating agents are commonly used to form complexes with different metal contaminants within the natural environment. The novelty of this work is to reduce the pollution load by ecofriendly method. The research gap adresses in this study is the reduction of nickel pollution by using chelating agent. In this study two chelating agents namely EDTA (Ethylene diamine tetra acetic acid) and DTPA (Diethylene triamine penta acetic acid) were used along with the nickel treated soil and also with soil without containing nickel to determine the efficiency of decontamination by a wild plant "Para grass" [Brachiaria mutica (Forssk.) Stapf] towards phytoremediation of nickel. In this experiment it was observed that the plant which were subjected to grow in EDTA with nickel treated soil accumulated more nickel than the other two sets which were subjected to grow in nickel treated soil with DTPA and also without chelating agent.

). It was found that the highest degree of oil destruction (up to 95%) was observed when using cultural liquid after cultivation of studied strains on hexadecane and liquid paraffins. The introduction of Cu 2+ (0.1-0.5 mM) in the exponential phase of IMB B-7241 and IMB Ac-5017 strains growth on non-hydrocarbon substrates (ethanol, waste oil) was accompanied by the formation of surfactants in the presence of which degree of decomposition of complex with heavy metals oil pollutions increased by 8-15% compared to using preparations synthesized in medium without copper cations. Intensification of oil destruction in the presence of such surfactants can be explained by activating influence of Cu 2+ on the activity of alkane hydroxylases (the first enzyme of n-alkanes catabolism in producers), and as a consequence, by the preliminary adaptation of cells to petroleum hydrocarbons assimilation.
