“…Heavy metal contamination in the soil and underground water seriously threatens surrounding fragile environments and human health ( Kim et al, 2001 ; Mohan et al, 2006 ; Bai et al, 2017 ; Chang et al, 2019 ; Chen et al, 2022a ; Hu et al, 2020 ; Bai et al, 2021 ; Hu et al, 2021 ; Liu et al, 2021 ; Xue et al, 2021 ; Hu et al, 2022 ; Wang et al, 2022 ). Such heavy metal contamination remediation by the traditional soil flushing measure is deemed time-consuming and costly since heavy metal ions are easily adsorbed by soil particles, and intensive industrial activities further aggravate heavy metal contamination ( Yang et al, 2014 ; An et al, 2019 ; Kumar and Dwivedi, 2019 ; Bai et al, 2021 ; Cheng et al, 2021 ; Duan et al, 2021 ; Wei et al, 2021 ; Yuan et al, 2021 ; Chen et al, 2022b ). In the past few years, various remediation measures, including but not limited to physical, chemical, and biological measures, have been proposed to deal with heavy-metal contamination ( Dhami et al, 2013 ; Shashank et al, 2016 ; Qian et al, 2017 ; Rahman et al, 2020 ; Ahenkorah et al, 2021a ; Hu et al, 2021 ; Jiang et al, 2021 ; and Xue et al, 2022 ).…”

Heavy metal contamination during the rapid urbanization process in recent decades has notably impacted our fragile environments and threatens human health. However, traditional remediation approaches are considered time-consuming and costly, and the effect sometimes does not meet the requirements expected. The present study conducted test tube experiments to reproduce enzyme-induced carbonate precipitation applied to lead remediation under the effects of urease concentration and a calcium source. Furthermore, the speciation and sequence of the carbonate precipitation were simulated using the Visual MINTEQ software package. The results indicated that higher urease concentrations can assure the availability of CO32− during the enzyme-induced carbonate precipitation (EICP) process toward benefiting carbonate precipitation. The calcium source determines the speciation of carbonate precipitation and subsequently the Pb remediation efficiency. The use of CaO results in the dissolution of Pb(OH)2 and, therefore, discharges Pb ions, causing some difficulty in forming the multi-layer structure of carbonate precipitation and degrading Pb remediation. The findings of this study are useful in widening the horizon of applications of the enzyme-induced carbonate precipitation technology to heavy metal remediation.

“…Yu et al (2016) tested Pseudomonas brassicacearum LZ-4 for the removal of Cr 6+ from wastewater and showed that this immobilized strain could remove 80% of 10 mg/L Cr 6+ [ 316 ]. A total of 93% Cr 6+ (10 mg/L) was successfully removed by An et al (2020) using Pseudomonas aeruginosa strain G12 in wastewater [ 317 ].…”

Chromium (Cr) exists in aqueous solution as trivalent (Cr3+) and hexavalent (Cr6+) forms. Cr3+ is an essential trace element while Cr6+ is a dangerous and carcinogenic element, which is of great concern globally due to its extensive applications in various industrial processes such as textiles, manufacturing of inks, dyes, paints, and pigments, electroplating, stainless steel, leather, tanning, and wood preservation, among others. Cr3+ in wastewater can be transformed into Cr6+ when it enters the environment. Therefore, research on Cr remediation from water has attracted much attention recently. A number of methods such as adsorption, electrochemical treatment, physico-chemical methods, biological removal, and membrane filtration have been devised for efficient Cr removal from water. This review comprehensively demonstrated the Cr removal technologies in the literature to date. The advantages and disadvantages of Cr removal methods were also described. Future research directions are suggested and provide the application of adsorbents for Cr removal from waters.

“…The Gram-negative mobile Proteobacteria represented by Pseudomonas aeruginosa, optionally anaerobic, have their habitat in soils, waters, human skin, etc. It grows both in normal and in lower oxygen atmospheres, thus colonizing many natural and artificial environments, metabolizes various organic substances, can decompose hydrocarbons, as well as reduce various compounds with nitrogen and heavy metals from residual water [31,32]. In addition, it can aggregate into biofilms [33] and possesses an intrinsic resistance to antibiotics [34].…”

The presence of nutrients in aquaculture water bodies causes serious problems for aquatic ecosystems, requiring the development of technical solutions to reduce their amounts. This work identifies some bacterial strains that are able to reduce nutrient quantities and studies the effect of antibiotics on bacterial growth, on the ability to form biofilms on different solid supports, and on the ability to reduce nutrients in aquaculture wastewater. Bacterial biofilm adhesion on different substrates depends on the surface properties of the substrate, on the bacterial types that form the biofilm, but also on biofilm–substrate interactions. The obtained results revealed the high capacity of biofilm-forming bacterial strains of Pseudomonas aeruginosa and Chromobacterium violaceum to eliminate up to 87% of nitrate and nitrite ions and up to 62% of phosphate ions in the presence of concentrations of 0.1–0.4 µg/mL of oxytetracycline antibiotic from aquaculture wastewater.
