“…This type of sensors enables ease detection, cost effectiveness and good reproducibility. In the same context, Heonseop Eom et al have established a sensing system based on the metabolic properties of SOB to oxidize sulfur (S 0 ) and produce sulfuric acid (SO 4 2− ) under aerobic conditions as it is shown in Equation (4) [ 22 , 124 ], leading to an augmentation in electrical conductivity (EC) and a lessening of pH. S 0 + H 2 O + 1.5O 2 → SO 4 2− + 2H + , ∆G 0 = −587 kJ/reaction …”

“…The presence of toxic substances leads to an inhibition in the SOB activity, causing less production of sulfuric acid, pH decreases and lower EC values. In their work, Heonseop Eom et al [ 124 ] have elaborated a fed-batch bioreactor based on the use of SOB for measuring Cr(VI) in water. An effective concentration (EC 50 ) of 1180 µg·L −1 was obtained after 2 h half exposure of Cr(VI) which makes it sensitive and suitable for the rapid determination of Cr(VI) in water.…”

The extensive use of chromium by several industries conducts to the discharge of an immense quantity of its various forms in the environment which affects drastically the ecological and biological lives especially in the case of hexavalent chromium. Electrochemical sensors and biosensors are useful devices for chromium determination. In the last five years, several sensors based on the modification of electrode surface by different nanomaterials (fluorine tin oxide, titanium dioxide, carbon nanomaterials, metallic nanoparticles and nanocomposite) and biosensors with different biorecognition elements (microbial fuel cell, bacteria, enzyme, DNA) were employed for chromium monitoring. Herein, recent advances related to the use of electrochemical approaches for measurement of trivalent and hexavalent chromium from 2015 to 2020 are reported. A discussion of both chromium species detections and speciation studies is provided.

“…As additives for improving the growth activity and microbial activity of microorganisms, biological growth promoters mainly include metals, non-metals [12][13][14]. Highconcentration metal ions are toxic to microorganisms [15,16]; however, it has been reported that suitable concentration metal ions can promote the activity of microorganisms [17]. The suitable concentrations of Zn(II) (lower than 5 mg/L) can strengthen microbe growth and the OD 600 value increased 0.006 [18].…”

“…

Copper (Cu) is a common and natural trace element in all environmental areas, including soil, air, water, and sediment. It plays a key role in plant respiration, photosynthesis, and some superoxide dismutase processes (Eom et al 2019). However, a high concentration of Cu in the soil leads to plant toxicity, which induces the dispersion of metal particles through wind erosion.

The phosphate precipitation of heavy metal induced by microorganisms plays an important role in immobilising heavy metal in soil. However, there is little knowledge about the effect of coexisting metal ions on the induction of Cu phosphate mineral and its stability. In this paper, the Cu phosphate precipitations, coexisting with Pb2+ or Ca2+ induced by strain LRP3, were characterised, and the stabilisation of the induced phosphate precipitates was also studied. The coexistence of Cu with Pb or Ca decreased the removal efficiency of Cu2+ by 17.18% and 9.78%, respectively, indicating the competitive adsorption between cations. Strain LRP3 could induce a new phosphate mineral of CuCa10(PO4)7 when coexisting with Ca and also generate the phosphate minerals of Pb(H2PO4)2 and Cu3(PO4)2 when coexisting with Pb. The Cu-Ca coprecipitate could enhance the stability of Cu in dilute acid solution and soil with or without a plant, whiles the Cu-Pb one showed the opposite effect. Also, the Cu-induced phosphate precipitates were relatively stable and not easy to be absorbed by Pakchoi (Brassica rapa var. chinensis). The results showed that the influence of coexisting metal ions should be considered when phosphate mineralisation technology is used to immobilise heavy metals in the environment.
