“…The relative abundances of starch and sucrose metabolism were also enriched in SW1, possibly as a result of the hydrolysis of starch and other substances by microbes in the WWR. Amino sugar and nucleotide sugar metabolism, starch and sucrose metabolism, and fructose and mannose metabolism were also reported in the simultaneous removal of V(V) and U(VI) reactors (Liu et al, 2022). The changes of alanine, aspartate, and glutamate metabolism; 2-oxocarboxylic acid metabolism; fatty acid metabolism; propanoate metabolism; citrate cycle (TCA cycle);butanoate metabolism; pentose phosphate pathway; peptidoglycan biosynthesis; phenylalanine, tyrosine and tryptophan biosynthesis; homologous recombination; folate biosynthesis; flagellar assembly; and bacterial secretion system (increasing in W1 and SW1 compared with that in RWW and S0) helped prove that V and WWR promoted the microbial activities.…”

Mining and smelting result in vanadium (V) being released into the environment. Biologically removing V(V) with washing water of rice (WWR) was investigated in this study. Over a 7-d trial, the V(V) removal efficiency increased with dosing washing water of rice dosage up to 56.6%. The results demonstrated that washing water of rice could be used as carbon and microbial sources for biologically reducing V(V). Using domesticated sludge as the inoculum could enhance V(V) detoxification performance, and 95.5% of V(V) was removed in the inoculated system for 5 d. Soluble V(V) was transformed into insoluble V(IV) (VO2), which could be further removed with precipitation. In addition to ABC transporters, a two-component system was also involved in V(V) reduction. The study confirmed that washing water of rice could be utilized for V(V) bio-detoxification.

“…In Bio-PRBs, the greatest k of V(V) reached 0.106 day –1 in 0–50 days and increased by 166–290% at other periods (0.0272, 0.0369, and 0.0399 day –1 ). Moreover, the η of V(V) and U(VI) simultaneously reached 99.5% and 80.7%, respectively, in Bio-PRBs . V(V) was reduced in preference to U(VI) due to its high redox potential.…”

Microbe–Mineral Interaction-Induced Microorganism-Augmented Permeable Reactive Barriers for Remediation of Contaminated Soil and Groundwater: A Review

et al. 2023

Conventional zerovalent iron permeable reactive barriers (PRBs) are limited by unknown iron corrosion kinetics and permeability loss, hindering access to desirable remediation targets. Against this background, microbe−mineral interactioninduced microorganism-augmented PRBs (Bio-PRBs) are considered a promising cutting-edge technology for increasing reaction rate k and enhancing removal efficiency η. This study provides original insights into the various active media and microbial carriers and the mechanisms of interaction among microorganisms, active media, and various contaminants. The results showed that microorganism-activated and microorganism-immobilized Bio-PRBs increased k and η by 40−2650% and 25−400%, respectively. In Bio-PRBs, the removal of contaminants involves the coupling of biodegradation, chemical reduction, and adsorption processes. Microorganisms promote the liquefaction of metal minerals into metal ions, thus forming a positive cycle by "microbe−mineral" interaction. Moreover, nonmetallic fillers affect k through synergistic effects of biodegradation, biological reduction, and electron donor groups. Microorganisms accelerate the e − transfer to promote the contaminants' transformation, and nonmetallic fillers are also conducive to improving diversity and abundance. Furthermore, some suggestions are made regarding the development and application of Bio-PRBs. Bio-PRBs provide efficient and novel approaches and strategies for eliminating soil and groundwater contamination based on microbe−mineral interaction and stimulation.

“…Due to its high water solubility, toxicity, and radioactive nature, it reduces the viability of cells and is considered as carcinogenic. Thus, strict regulations are being implemented by the World Health Organization (WHO) and the U.S. Environmental Protection Agency (USEPA), with the threshold limits for uranium in drinking water being 15 and 30 ppb, respectively. ,− In light of this, one of the most crucial and effective solutions for protecting the environment and human health is to remove uranium from aqueous solutions …”

The efficient removal of uranium ions from aqueous and simulated seawater is reported by using a mixed matrix membrane (MMM-2) fabricated by cyclophosphazene and triazine-based inorganic−organic hybrid material (CTHM-2) as the adsorbent. CTHM-2 with a specific surface area of 76 m 2 g −1 was synthesized within 60 min by microwave-assisted polycondensation reaction. In batch mode adsorption, the concentration of uranium has been decreased from 5 ppm to <15 ppb (permissible limit of uranium by the World Health Organization) within 120 min at pH of 6 and 298 K. However, a maximum adsorption capacity of 580 mg g −1 is estimated with 500 ppm of the initial concentration. The isotherm and kinetic studies indicate that it could fit well with the Freundlich isotherm and pseudo-second order kinetics. The negative ΔG and ΔH values indicate the spontaneous and exothermic adsorption processes, respectively. When the MMM-2 was used to treat 5 L of 5 ppm U(VI) solution, with a water flux of 8.1 L m −2 h −1 and 2 bar transmembrane pressure, it provides safe drinkable water (<15 ppb) for 300 min. Additionally, the CTHM-2 and MMM-2 could be further used to remove uranium ions from the simulated seawater with adsorption capacities of 53 and 167 mg g −1 , respectively.
