“…This rapid reduction of hexavalent chromium could be ascribed to surface binding due to the presence of different functional groups on cell wall and interior penetration (bioaccumulation) as reported previously (Rehman, Shakoori & Shakoori, 2006; Khan et al, 2015; Bingöl, Özmal & Akın, 2017; Long et al, 2017; Zhenggang et al, 2018). It was observed that the peaks attributed for amide linkages appearing at 1,620 and 1,526 cm −1 were shifted respectively to 1,625 and 1,521 cm −1 on adsorption of chromium (Mungasavalli, Viraraghavan & Jin, 2007; Park, Yun & Park, 2005).…”

“…The suppression and shift in peak intensity ranging 1,000–1,320 cm −1 , denoting the presence of phosphorous and carbon containing oxygen atoms, indicated their interaction with Cr +6 (Das & Guha, 2007). It seems that the bacterial cells have undergone the oxidation during biosorption of chromium that has resulted into changes in overall IR spectrum (Park, Yun & Park, 2005; Long et al, 2017). These functional groups have previously been reported to interact with metal ions (cations) (Bueno et al, 2008).…”

Background Urbanization and industrialization are the main anthropogenic activities that are adding toxic heavy metals to the environment. Among these, chromium (in hexavalent: Cr+6 and/or trivalent Cr+3) is being released abundantly in wastewater due to its uses in different industrial processes. It becomes highly mutagenic and carcinogenic once it enters the cell through sulfate uptake pathways after interacting with cellular proteins and nucleic acids. However, Cr+6 can be bio-converted into more stable, less toxic and insoluble trivalent chromium using microbes. Hence in this study, we have made efforts to utilize chromium tolerant bacteria for bio-reduction of Cr+6 to Cr+3. Methods Bacterial isolate, K1, from metal contaminated industrial effluent from Kala Shah Kaku-Lahore Pakistan, which tolerated up to 22 mM of Cr6+ was evaluated for chromate reduction. It was further characterized biochemically and molecularly by VITEK®2 system and 16S rRNA gene sequencing respectively. Other factors affecting the reduction of chromium such as initial chromate ion concentration, pH, temperature, contact-time were also investigated. The role of cellular surface in sorption of Cr6+ ion was analyzed by FTIR spectroscopy. Results Both biochemical and phylogenetic analyses confirmed that strain K1 was Staphylococcusaureus that could reduce 99% of Cr6+ in 24 hours at 35 °C (pH = 8.0; initial Cr6+ concentration = 100 mg/L). FTIR results assumed that carboxyl, amino and phosphate groups of cell wall were involved in complexation with chromium. Our results suggested that Staphylococcusaureus K1 could be a promising gram-positive bacterium that might be utilized to remove chromium from metal polluted environments.

Industrial waste is mainly responsible for accumulating Zn (II) in the soil, which needs to be removed to avoid its bioaccumulation and hazardous effects on the environment. In a recent study, the potential of the RY12 strain was evaluated as a biosorbent of Zn (II) ions in an aqueous medium. Different microbiological techniques like biochemical, molecular characterization, and 16S rRNA gene sequencing were used for the identification of RY12. The impact of different parameters such as the initial zinc ion concentration, pH, temperature, and the removal of other metals such as manganese, lead, cobalt, silver, copper, mercury, and chromium was also evaluated on the reduction of Zn (II). Fourier Transform Infrared spectroscopy (FTIR) was also carried out to investigate the role of cellular surfaces in the sorption of Zn+2 ions. Both biochemical and phylogenetic analyses established that strain RY12 Pseudomonas sp. capable of reducing Zn+2 up to 89% at 28°C (pH = 6.5; initial Zn+2 concentration = 200 mg/L). The FTIR analysis revealed that the bacterial cell wall’s amino, carboxyl, and phosphate groups were involved in the reaction with Zn (II). Our findings suggest that Pseudomonas sp. RY12 is a proficient bacterium for removing zinc from industrial waste and could be a valuable bioremediation agent.

“…Pure Tl is bluish-white in color and it is very soft and malleable. Thallium is considered to be more toxic than Pb, As, Hg, Cd and Cu, with a lethal dose reported to be 10-15 mg/kg in humans [2][3]. It is a cumulative poison, with symptoms of intoxication including alopecia, nausea, persistent weakness, tachycardia, high blood pressure, abdominal pain, vision loss and so on [2].…”

“…The Maximum Permissible Level of Tl in drinking water is fixed at 2 μg/L by the U.S. EPA [4], 0.8 μg/L by Canada and 0.1 μg/L by China and Russia [2,4]. The predominant source of Tl released into the environment is industrial activities utilizing Tl-bearing minerals, such as smelting of Pb, Cu, and Zn ores, rather than from facilities producing or using Tl compounds [1][2][3][4][5][6][7]. Tough Tl is highly toxic and has often been excluded from the list of metals to be supervised before 2010, when a serious Tl pollution incidence occurred in the northern branch of the Pearl River -the 3 rd longest river in China.…”

Thallium (Tl) is a typical trace metal of extreme high toxicity. As a concomitant element, Tl is widely found in various sulfide minerals and K-containing rock minerals. The outburst of Tl pollution in drinking water sources of the northern branch of the Pearl River in China as reported in 2010 has greatly aroused public concerns about Tl pollution in China. Apart from typical sources of Tl pollution such as Pb and Zn smelting and the mining and utilization of Tl-containing pyrite ores, the steel-making industry was discovered a new significant source that contributed to this Tl pollution incidence. Thallium contents in raw materials, fly ash and wastewater collected from a typical steel-making enterprise were determined by inductively coupled plasma mass spectrometry (ICP-MS). The results showed that Tl contents (0.02-1.03 mg/kg) are generally low in the raw materials, while fly ash samples have generally enriched Tl levels (1.31-6.45 mg/kg). Wastewater obtained from the dedusting process of the sintering furnace also exhibited excessive Tl levels (574-2130 μg/L). All these results suggested a possible release and gasification of Tl compounds from the raw materials under high temperatures (>800ºC) during the sintering processes, which were then accumulated in the flue gas and fly ash and washed into the wastewater by wet dedusting. Lime precipitation method is not effective for removing Tl from wastewater, since Tl mostly is present as dissolved Tl + in the water. The study initiated a preliminary design of a fast and effective treatment method for Tl removal from Tl-containing industrial wastewater by using a deep oxidation system.
