“…encoding for zinc ABC (ATP-binding cassette) transporter permease; zinc-binding protein; zinc transporter ZntB; the zinc import ATP-binding protein ZnuC; zinc ABC transporter substrate-binding protein; and, cadmium-, zinc-, and mercury-transporting ATPase. Bacteria also adapt themselves to heavy metal stress by developing various resistance mechanisms via intracellular metalbinding proteins [87]. The ability of our PSB strains, especially Enterobacteria, to tolerate higher concentrations of heavy metal provides a scope of their potential use as potential bioremediator agents, as previously reported [88].…”

Introduction of quinoa (Chenopodium quinoa willd.), a gluten-free nutritious pseudo-cereal, outside its traditional growing areas exposed it to seedling damping-off. Here, we isolated eleven phosphate-solubilizing bacteria from the quinoa rhizosphere and assessed their effect on germination and seedlings growth. All isolates solubilized phosphate, produced indole3-acetic acid, hydrocyanic acid, siderophores, and ammonia. Genotypic analysis revealed that our strains are related to the genus of Bacillus, Pseudomonas, and Enterobacter. Strains Enterobacter asburiae (QD14, QE4, QE6, and QE16), Enterobacter sp. QE3, and Enterobacter hormaechei QE7 withstood 1.5 mg·L−1 of cadmium sulfate, 0.5 mg·mL−1 of nickel nitrate, and 1 mg·mL−1 of copper sulfate. Moreover, all strains solubilized zinc from ZnO; P. Stutzeri QD1 and E. asburiae QD14 did not solubilize Zn3(PO4)2 and CO3Zn, whereas CO3Zn was not solubilized by E. asburiae QE16. Bacillus atrophaeus S8 tolerated 11% NaCl. P. frederiksbergensis S6 and Pseudomonas sp. S7 induced biofilm formation. Anti-fusarium activity was demonstrated for E.asburiae QE16, P. stutzeri QD1, P. frederiksbergensis S6, Pseudomonas sp. S7, and B. atrophaeus S8. Lastly, inoculation of quinoa seeds with B. atrophaeus S8 and E. asburiae QB1 induced the best germination rate and seedling growth, suggesting their potential use as inoculants for salty and heavy metal or zinc contaminated soils.

With the contest of urbanization and industrial development, electroplating industries have grown rapidly. The different chemicals, metal salts and discharge of large volume of wastewater with inefficient treatment facilities had created the pollution load on water bodies. The present study was carried out to investigate the assessment of the monthly variation of pH and heavy metals (Cr, Ni, Zn, Fe) of electroplating untreated industrial wastewater from the selected study sites viz. SS-1: Atul Industries, SS-2: Suresh Fasteners, SS-3: Bajrang Industrial Company, SS-4: Stylex Industries, SS-5: Karan Industries, SS-6: Avon Industries, SS-7: Geetika Enterprises, SS-8: Atop Fasteners, SS-9: Accufit Fasteners and SS-10: Ashoka Furniture Udyog at industrial area phase I and phase II of Chandigarh. The untreated electroplating wastewater samples were collected from ten study sites (SS-1 to SS-10) and were analyzed following the standard methods for the examination of water and wastewater. The results of the present study revealed that the maximum concentration of heavy metals such as Zn (122.20 mg/l)during the month of August 2019 at the SS-8, Ni (156.37 mg/l) during the month of August 2019 at the SS-4, Cr (467.01 mg/l) during the month of October 2019 at the SS-5 and Fe (13.22 mg/l)during the month of December 2019 at the SS-2. The load of metallic ions discharge from the electroplating industries before any treatment from the selected study sites (SS-1 to SS-10) was found in the following order as Cr>Ni>Zn>Fe. Thus the present study would provide baseline data for the development of treatment strategies for wastewater discharge from electroplating industries and also in minimizing the effects of heavy metal contamination of receiving water bodies.
