World population growth, with the consequent consumption of primary resources and production of waste, is progressively and seriously increasing the impact of anthropic activities on the environment and ecosystems. Environmental pollution deriving from anthropogenic activities is nowadays a serious problem that afflicts our planet and that cannot be neglected. In this regard, one of the most challenging tasks of the 21st century is to develop new eco-friendly, sustainable and economically-sound technologies to remediate the environment from pollutants. Nanotechnologies and new performing nanomaterials, thanks to their unique features, such as high surface area (surface/volume ratio), catalytic capacity, reactivity and easy functionalization to chemically modulate their properties, represent potential for the development of sustainable, advanced and innovative products/techniques for environmental (bio)remediation. This review discusses the most recent innovations of environmental recovery strategies of polluted areas based on different nanocomposites and nanohybrids with some examples of their use in combination with bioremediation techniques. In particular, attention is focused on eco-friendly and regenerable nano-solutions and their safe-by-design properties to support the latest research and innovation on sustainable strategies in the field of environmental (bio)remediation.

Patulin (PAT), a mycotoxin produced primarily by Penicillium expansum, poses significant health risks and frequently contaminates apples and apple-derived products, often exceeding permissible safety limits. This study investigated the potential of orotate phosphoribosyl transferase (URA5) to degrade PAT in apple juice under controlled conditions. PAT degradation was assessed at initial concentrations of 100 µg/L and 250 µg/L, with enzymatic treatment using 0.

Environmental sustainability is seriously threatened by the discharge of wastewater containing hazardous heavy metals (such as Cr, Cd, As, Hg, etc.). The utilization of microalgae has recently come to light as a viable, environmentally acceptable method for removing heavy metals from contaminated sites.

The nitrogen-fixing, chemolithoautotrophic genus is found across numerous diverse environments worldwide and is an important member of many ecosystems. These species serve as model systems for their metabolic properties and have industrial applications in bioremediation and sustainable protein, food and fertilizer production. Despite their abundance and utility, the majority of strains are without a genome sequence, and only eight validly published species are known to date.

Chlorinated hydrocarbons are widely used as solvents and synthetic intermediates, but their chemical persistence can cause hazardous environmental accumulation. Haloalkane dehalogenase from (DhlA) is a bacterial enzyme that naturally converts toxic chloroalkanes into less harmful alcohols. Using a multiscale approach based on the empirical valence bond method, we investigate the catalytic mechanism of 1,2-dichloroethane dehalogenation within DhlA and its mutants.

Global salinization increasingly threatens ecosystem integrity and the regulation of biogeochemical cycles. Our study reveals novel insights into the microbial contributions to the organohalide decomposition in saline environments, demonstrating the unprecedented ability of organohalide-respiring bacteria and to completely dechlorinate trichloroethene to non-toxic ethene under hypersaline conditions (up to 31.3 g/L) in long-term operations.
