“…A similar result was obtained with a cadmium-tolerant bacterium, Enterobacter ludwigii LY6: the cadmium chloride removal rate of this strain with a treatment of 100 mg/L of cadmium chloride reached 56.0 %. In this strain, the expression of several genes closely related to bacterial cadmium tolerance and biosorption increased with the increase in the cadmium concentration [91]. Taking this into account, genetic modification is also a very useful tool to achieve resistant strains that can be used as living biomass, and therefore, with better biosorption capacity.…”

“…Thus, cadmium biosorption studies with the Simplicillium chinense QD10 strain [94] and with Shewanella putrefaciens [95] used as living cells suggested that the cell wall components were the primary interactive targets for this metal. Cadmium sulfide nanoparticles can also form on the cell surface, which contributes to the excellent tolerance to this metal of E. ludwigii LY6 [91]. Additionally, on the cell surface, the exopolysaccharides (EPS) might be the main means of cadmium adsorption by some strains [91].…”

Biosorption is a variant of sorption techniques in which the sorbent is a material of biological origin. This technique is considered to be low cost and environmentally friendly, and it can be used to remove pollutants from aqueous solutions. The objective of this review is to report on the most significant recent works and most recent advances that have occurred in the last couple of years (2019–2020) in the field of biosorption. Biosorption of metals and organic compounds (dyes, antibiotics and other emerging contaminants) is considered in this review. In addition, the use and possibilities of different forms of biomass (live or dead, modified or immobilized) are also considered.

“…Enterobacteria are promising nanoparticle-synthesizing bacteria based on the advantages of rapid, nonpolluted and nontoxic reaction, cost-effectiveness, easy purification of nanoparticles in supernatant, and size of nanoparticles [ 46 , 47 , 48 , 49 ]. Previous studies reported the ability of enterobacteria to synthesize various nanoparticles such as gold [ 49 , 50 ], silver [ 51 , 52 ], selenium [ 53 ], lead [ 54 ], and cadmium sulfide [ 55 ].…”

Enterobacteria that commonly inhabit marine environments have a great impact on human health. In this study, enterobacteria isolated from seawater in the Upper Gulf of Thailand were identified and characterized. Seawater from nine sampling sites along the Upper Gulf of Thailand contained presumptive enterobacteria that ranged from 0.22 ± 0.44 to 17.00 ± 3.97 CFU/mL. The 101 strains belonged to seven species in which Klebsiella pneumoniae was the majority (47.5% of strains). The highest prevalence was resistant to ampicillin (76.2%) and ticarcillin (72.3%), respectively, whereas none was resistant to imipenem. Forty-five antibiotic resistance patterns were observed and 33.7% exhibited multidrug resistance, emphasizing the concern about public health. Three β-lactamase genes, including ampC, blaSHV, and blaTEM, were detected at the frequencies of 47.5%, 21.8%, and 11.9%, respectively. Six virulence genes, including csgD, uge, kfu, eaeA, magA, and LTI, were detected at the frequencies of 37.6%, 31.7%, 19.8%, 16.8%, 12.9%, and 5.9%, respectively. The condition of 4% NaCl downregulated the expression of the kfu and uge genes. The 67.3% and 63.4% of strains synthesized silver nanoparticles ranging between 3.04 ± 0.64 and 20.64 ± 0.95 μg/mL and gold nanoparticles ranging between 7.77 ± 0.45 and 57.57 ± 8.00 μg/mL, respectively.

“…Due to the fact that biostimulation, bio fertilization, biocontrol and sometimes by biosorption are multitask phenomenon and in this scenario, bacteria of a group of PGPR impart tolerance to biotic and abiotic stresses including heavy metals. Cadmium (Chi et al, 2020;Wang et al, 2020), Klebsiella pneumoniae and Citrobacter freundii for lead exhibited their potential in promoting the plant growth in heavy metals contaminated soil (Al-Garni, 2005). Soil can be contaminated by many polluting sources, such as composts, pesticides, emissions from municipal waste sites, metal smelting industry, etc.…”

The Cadmium tolerance by root nodulating bacteria Ensifer adhaerens KS23 inhabiting in Pisum sativum L. var. Arkel revealed linear relationship with inorganic salt cadmium sulphate (CdSO4) upto 200 μg/ml, corresponding to growth and survival in solid as well as liquid Yeast Extract Mannitol (YEM) medium with LC50 value of 107.2 μg/ml and LC95 of 184.5 μg/ml. The results of phylogenetic and morpho-physiological analysis exhibited the genus E. adhaerens. KS23 was found to be the most promising among all the 20 isolates. The increase in Glutathione S-transferase (GST) activity by KS23 was 9.7 fold under Cd stress. Wherein, P and F values were <0.05 and 26.54 respectively and predicted r2 value of 0.8192 and adjusted r2 value 0.8908 were reasonable (i.e. <0.2) of the Box Behnken design. The data showed that 81.24% cadmium bio-removal achieved at pH 6.0, 30°C and 168 h of incubation while supplementing the YEM medium with 25 μg/ml cadmium. Further, its effect on plant growth and development exhibited due to production of IAA, secretion of siderophores, phosphate solubilisation and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity by E. adhaerens KS23. In addition to inherent PGP attributes, Cd tolerant E. adhaerens KS23 played dual role of biosorption of cadmium and upsurge in growth promotion of P. sativum which may provide a new root-nodulating bacterium inhabiting in P. sativum cultivated at high altitudes of Himalayan region.
