Adsorption of Cd2+ by Lactobacillus plantarum Immobilized on Distiller’s Grains Biochar: Mechanism and Action

Microorganisms, Год журнала: 2024, Номер 12(7), С. 1406 - 1406

Опубликована: Июль 11, 2024

Immobilized microbial technology has recently emerged as a prominent research focus for the remediation of heavy metal pollution because its superior treatment efficiency, ease operation, environmental friendliness, and cost-effectiveness. This study investigated adsorption characteristics mechanisms Cd2+ solutions by Lactobacillus plantarum adsorbed immobilized on distiller’s grains biochar (XIM) plantarum–encapsulated (BIM). The findings reveal that maximum capacity efficiency were achieved at pH solution 6.0. Specifically, an equilibrium concentration cadmium 60 mg/L, XIM BIM had capacities 8.40 ± 0.30 mg/g 12.23 0.05 mg/g, respectively. demonstrated noticeably greater than various concentrations. A combination isothermal modeling, kinetic scanning electron microscopy–energy dispersive X-ray spectroscopy, diffractometer (XRD), Fourier-transform infrared spectroscopy (FTIR) analyses showed primarily involved physical pore retention. In contrast, mechanism was mainly attributed to formation Cd(CN)2 crystals.

In Situ and Ex Situ Bioremediation of Different Persistent Soil Pollutants as Agroecology Tool

Processes, Год журнала: 2024, Номер 12(10), С. 2223 - 2223

Опубликована: Окт. 12, 2024

Contamination or pollution of our environment has become a real global concern, especially in parallel with the increasing evolution urbanization and industrialization, which turn have released plethora different pollutants that end up being deposited soils. It is crucial to investigate solutions can minimize extent damage, are cost-effective, feasible environmentally friendly, treat wide variety contaminants soils, as well detoxify various compounds. Bioremediation safe technique demonstrated satisfactory results easy apply maintain. This explores degradation pathways biological agents (microorganisms, plants, algae, etc.) neutralize contaminants. based on biodegradation through complete mineralization organic into inorganic innocuous compounds, such carbon dioxide water. review aims determine feasibility bioremediation cleanup technology for soils contaminated pesticides, agrochemicals, chlorinated heavy metals, halogens, greenhouse gases, petroleum hydrocarbons, many others, either situ ex situ. Different approaches described compared, showing their advantages drawbacks from critical point view. Moreover, both economic technical barriers addressed, along outlook role microorganisms process, aim identify future directions, application this process.

Loading organic phosphorus-degrading bacteria enhanced biochar performance for heavy metals adsorption

Environmental Technology & Innovation, Год журнала: 2024, Номер 34, С. 103585 - 103585

Опубликована: Март 1, 2024

As a porous material, biochar has been endowed with high expectations to be the carrier for heavy metals-tolerant microorganism loading due its excellent performance. Therefore, derived from green walnut husk was used in this study load screened metal-tolerant organic phosphorus-degrading bacteria OPB3-6-1 metals remediation. The results suggested that loaded (IOPB) exhibited synergistic effect adsorbing of Pb2+, Cu2+ and Cd2+, while IOPB500 (carrier prepared under 500℃ pyrolysis temperature) obtained highest adsorption potential as capacities Cd2+ reached 591.0, 300.0 20.0 mg/g certain initial concentration, respectively. In addition, dosage, reaction temperature pH posed different effects on adsorption, top capacity condition 1 g/L 30℃ 6~7 pH. kinetics isotherms monolayer chemical dominated whole process intra-particle diffusion played greater role rate control. Compared intracellular uptake, extracellular complexation accounted major contribution OPB3-6-1, which facilitated IOPB since such functional groups P=O, P-OH PO43- were detected by FTIR. After applying into metal contaminated soil, exchangeable fraction decreased 15.7%, 19.0% 23.24%, residual content increased 15.9%, 9.3% 11.5%, respectively, thereby alleviated toxicity risks metals. Overall, conclusion proved biochar-bacteria coupled systems remediation applications.
