The electrochemical properties of chars have been recently described, positioning as active participants in microbial redox processes through functional groups, aromatic structures, redox-active metals, and radicals. While bench-scale studies advanced mechanistic understanding char's behavior potential effects, translating these findings to complex ecosystems remains challenging. This is mainly due the complexities communities unique various ecosystems. Factors like char aging patina formation, environmental parameters including oxygen moisture availability, pH, organic matter content can significantly affect interactions. highlights need for a broader predict effectively manage unintended impacts or enhance beneficial effects. Long-term monitoring systems amended with also needed determine whether accumulation has long-term effects on ecosystem services, biogeochemical cycling. Predictive would inform production such increased soil productivity, provide new opportunities engineered remediation. Here, we summarize how well-defined discuss key factors that are enhanced attenuated systems. We identify critical knowledge gaps about chars' role important sustainability postulate managing properties, electron donating, accepting, conducting ability, an emerging opportunity influence services.

Abstract Heavy metals (HMs) like Zn, Cu, Pb, Ni, Cd, and Hg, among others, play a role in several environmental problems. The marine environment is polluted by contaminants, such as HMs. A variety of physico-chemical methods usually available for sanitation HMs remediation suffer from either limitation. Bioremediation promising way dealing with pollution. Microbes have the ability various potencies to resist tension. current review discusses main sources influences HMs, microorganisms bioremediation, well microbial mechanisms detoxification transformation. This paper aims provide an overview bioremediation technologies that are currently removal ions industrial urban effluent aquatic organisms bacteria, fungi, microalgae, particularly those isolated areas. primary goals outline studies offer helpful information about most important aspects bioelimination techniques. biotreatment practices been primarily divided into three techniques based on this topic. They biosorption, bioaccumulation, bioleaching, biotransformation. article gives brief view research using microorganisms. also deals critical issues recent biodetoxification

Abstract The use of pesticides and the subsequent accumulation residues in soil has become a worldwide problem. Organochlorine (OC) have spread widely environment caused contamination from past agricultural activities. This article reviews bioremediation pesticide compounds using microbial enzymes, including enzymatic degradation pathway recent development enzyme-mediated bioremediation. Enzyme-mediated is divided into phase I II, where former increases solubility through oxidation–reduction hydrolysis reactions, while latter transforms toxic pollutants less or nontoxic products conjugation reactions. identified enzymes that can degrade OC insecticides include dehalogenases, phenol hydroxylase, laccases. Recent developments to improve immobilization, encapsulation, protein engineering, which ensure its stability, recyclability, handling storage, better control reaction.

Although bioremediation is considered the most environmentally friendly and sustainable technique for remediating contaminated soil water, it effective when combined with physicochemical methods, which allow preliminary removal of large quantities pollutants. This allows microorganisms to efficiently eliminate remaining contaminants. In addition requiring necessary genes degradation pathways specific substrates, as well tolerance adverse environmental conditions, may perform below expectations. One typical reason this high toxicity xenobiotics present in concentrations, stemming from vulnerability bacteria introduced a site. especially true planktonic bacteria, whereas within biofilms or microcolonies have significant advantages over their counterparts. A physical matrix essential formation, maintenance, survival bacterial biofilms. By providing such immobilization, formation can be facilitated accelerated. Therefore, immobilization offers comprehensive solution cleanup by harnessing specialized metabolic activities while ensuring retention efficacy at target sites. many cases, also need methods that are otherwise required initially reduce contaminant concentrations. Then, will possible use remediation higher concentrations xenobiotics, significantly reducing costs maintaining rapid rate processes. review explores benefits highlighting materials processes developing an optimal matrix. It focuses on following four key areas: (i) types organic pollutants impacting human health, (ii) strains used processes, (iii) (iv) cells various carriers targeted pollutant degradation.

Mismanaged plastics, upon entering the environment, undergo degradation through physicochemical and/or biological processes. This process often results in formation of microplastics (MPs), most prevalent form plastic debris (<1 mm). MPs pose severe threats to aquatic and terrestrial ecosystems, necessitating innovative strategies for effective remediation. Some photosynthetic microorganisms can degrade but there lacks a comprehensive review. Here we examine specific role photoautotrophic water soil environments biodegradation focussing on their unique ability grow persistently diverse polymers under sunlight. Notably, these cells utilise light CO2 produce valuable compounds such as carbohydrates, lipids, proteins, showcasing multifaceted environmental benefits. We address key scientific questions surrounding utilisation nanoplastics (NPs) bioremediation, discussing potential engineering enhanced efficacy. Our review highlights significance alternative biomaterials exploration strains expressing enzymes, polyethylene terephthalate (PET) hydrolases, conjunction with microalgal cyanobacterial metabolisms. Furthermore, delve into promising photo-biocatalytic approaches, emphasising coupling sunlight exposure. The integration microalgal-bacterial consortia is explored biotechnological applications against NPs pollution, synergistic effects wastewater treatment absorption nitrogen, heavy metals, phosphorous, carbon. In conclusion, this provides overview current state research use bioremediation. It underscores need continued investigation development approaches tackle global issue pollution ecosystems.
