“…At low pHs, the biomass surface is highly protonated, offering a large amount of positive charges that attract chromium anions. Obviously, this pH range cannot be used with living biomass; however, the biological activity of this type of biomass can compensate for this inconvenience, especially using resistant strains [85]. This behavior can be applied to other metals such as dysprosium [88], arsenic [89] or tungsten [20].…”

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.

“…Cr(VI) causes many diseases in humans, such as skin rash, kidney and liver damage, internal bleeding, dental abnormalities, respiratory disorders, and lung cancer (Martone et al 2013). Cr(VI) is 100 times toxic and 1000 times more mutagenic compared to Cr(III) (Chang et al 2019). Reducing Cr(VI) to Cr(III) in Cr(VI) removal is therefore an effective method for signi cantly reducing the toxic effect of Cr(VI) (Long et al 2018;Pan et al 2014).…”

“…Cr(VI) is recognized as one of the priority pollutants by the United States Environmental Protection Agency (USEPA) (USEPA 2014). It has been reported that the discharge limit of wastewater containing Cr(VI) made by European Union (EU) to surface waters should be below 0.05 mg/L and that the total concentration of Cr should be reduced below 2 mg/L (Chang et al 2019). The World Health Organization (WHO) has determined the maximum allowable total chromium content in surface water and drinking water to be 0.05 mg/L (WHO 2017).…”

Studies on the removal of toxic metals from water by genetic engineering applications are becoming more and more diverse. Especially by the expression of cysteine and thiol rich proteins such as metallothioneins in bacterial cells, a high rate of removal of metal ions from the environment is ensured. In this study, we evaluated the removal and reduction of hexavalent chromium Cr(VI)from aqueous solutions with the recombinant strains obtained by cloning the human metallothioneinsMT2A and MT3 into Escherichia coli Jm109.E. coli MT2A was the most effective strain in both Cr(VI) removal (89%in 25 mg/L Cr(VI) application) and Cr(VI) reduction (76%in 25 mg/L Cr(VI) application).Cr(VI) adsorbed per dry cell (at 25 mg/L) were 17 mg/g, 22 mg/g and 19 mg/g for Jm109, MT2A and MT3, respectively. Scanning electron microscope (SEM) images showed that the morphological structures of Cr(VI)treated cells were signi cantly damaged compared to control cells. Scanning transmission electron microscope (STEM) images showed black spots in the cytoplasm of cells treated with Cr(VI).From the shifts in the Fourier transform infrared spectroscopy analysis (FTIR) spectra of the cells treated with Cr(VI) compared to the control cells, it was determined that the groups interacting with Cr were amino, hydroxyl, methyl and sulfhydryl. When all these experimental data were evaluated together, it was concluded that all three species were effective in removing Cr(VI) from aqueous solutions and MT2A strain could be used as the most effective biotechnological tool.

“…Moreover, it has been suggested that chromium (III) is involved in maintaining the tertiary structure of proteins and inducing DNA conformational changes [34,35]. Thus, biotransformation of chromium (VI) to chromium (III) via microbial or plant metabolism has been considered a feasible and practical process for the detoxification of environmental chromium (VI) contaminants [13][14][15]. However, increasing evidence suggests that chromium (III), although much less toxic than chromium (VI), can also induce cytotoxicity via increased apoptosis and oxidative stress [18][19][20][21][22].…”

“…The prevailing view is that chromium (III) is an essential element for carbohydrate and lipid metabolism and that it is noncarcinogenic and much less toxic to most organisms than chromium (VI) [10][11][12]. Thus, the biotransformation of chromium (VI) to chromium (III) via the metabolic pathways of plants and microorganisms has been considered a feasible and practical process to detoxify environmental chromium (VI) contaminants [13][14][15].…”

Chromium in its trivalent form (chromium (III)) is an essential component of a balanced diet, and its deficiency disturbs glucose and lipid metabolism in humans and animals.The prevailing view is that chromium (III) is notably less toxic than chromium (VI), which is genotoxic and carcinogenic. Thus, the biotransformation of environmental chromium (VI) to chromium (III) is a promising and environmentally friendly detoxification method. However, increasing evidence suggests that chromium (III) induces considerable cytotoxicity. However, the toxicity of chromium (III) to early embryos remains largely unknown. In the present study, we used in vitro fertilization (IVF) to produce mouse embryos and identified the direct embryotoxicity of chromium (III). On exposure to high concentrations of CrCl 3 , blastocyst formation almost completely failed and a large proportion of embryos were arrested at the 2-to 4-cell stage. At low concentrations of CrCl 3 , IVF embryos showed a significant decrease in blastocyst formation, reduced total cell numbers, aberrant lineage differentiation, increased oxidative stress, and apoptosis. We also found that chromium (III) exposure during the preimplantation stage, even at low concentrations, led to impaired postimplantation development. Thus, our study substantiates the direct embryotoxicity of chromium (III) during preimplantation development and prolonged impairment of development potential. The results further highlight the potential adverse effects of chromium (III) on public reproductive health with respect to increased environmental enrichment of and dietary supplementation with chromium (III) complexes.
