The urbanization process, which began with the Industrial Revolution, has undergone a considerable increase over past few decades. Urbanization strongly affects ecological processes, often deleteriously, because it is associated decrease in green spaces (areas of land covered by vegetation), loss natural habitats, increased rates species extinction, greater prevalence invasive and exotic species, anthropogenic pollutant accumulation. In urban environments, play key role providing many benefits contributing to human psychophysical well-being. It known that interactions between plants microorganisms occur rhizosphere are paramount importance for plant health, soil fertility, correct functioning ecosystems. growing diffusion DNA sequencing technologies "omics" analyses provided increasing information about composition, structure, function rhizomicrobiota. However, despite amount data on communities their natural/rural contexts, current knowledge microbial roots soils still very scarce. present review discusses both plant-microbe dynamics factors drive composition rhizomicrobiota poorly investigated settings potential use beneficial microbes as an innovative biological tool face challenges anthropized environments climate change impose. Unravelling biodiversity will contribute space management, preservation, development and, ultimately, public health safety.

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.

Soil contamination with chromium (Cr) is a serious and burgeoning environmental problem. The infiltration of excess Cr into the food chain causes number human health issues, including respiratory disorders, cardiovascular diseases, renal failure, several types cancer. pollution can be contained by different physical, chemical, biological remediation approaches. Physical chemical methods are costly hazardous to environment as they cause secondary pollution. Biological approaches such bioremediation that employ plants (phytoremediation) microbes eco-friendly, efficient, cost-effective. Nonetheless, conventional phytoremediation encounters limitations in large-scale use due restricted pool hyperaccumulator plant species, slow growth rate, limited biomass production, plant-contaminant specificity, contaminant-mediated oxidative stress plants. Interestingly, bacteria fungi have potential survive thrive under extreme conditions. Plant growth-promoting (PGPB) utilize siderophores, organic acids, biosurfactants, redox mechanisms, biomethylation convert metals soluble bioavailable forms. Further, these involved synthesizing phytohormones 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase, acquisition iron, nitrogen fixation, phosphorus solubilization, which improve biomass, thereby aiding phytoremediation. This literature review encompasses breadth research conducted over preceding decade, underscoring contemporary remedial primary focus on crucial role facilitating Cr. Moreover, this spotlights underlying mechanisms microbe-assisted betterment grown Cr-contaminated soils.

Harnessing in situ microbial communities to clean-up polluted natural environments is a potentially efficient means of bioremediation, but often the necessary genes breakdown pollutants are missing. Genetic bioaugmentation, whereby required delivered resident bacteria via horizontal gene transfer, offers promising solution this problem. Here, we engineered conjugative plasmid previously isolated from soil, pQBR57, carry synthetic set allowing consume terephthalate, chemical component plastics commonly released during their manufacture and breakdown. Our caused low fitness cost was stably maintained terephthalate-contaminated soil by bacterium P. putida. Plasmid carriers efficiently bioremediated contaminated model microcosms, achieving complete 3.2 mg/g terephthalate within 8 days. The horizontally transferred operon fluorescens situ, resulting transconjugants degraded 10 mM 180-h incubation. findings show that environmental plasmids carrying catabolic operons can be useful tools for engineering perform even complex like soil.

ABSTRACT Achromobacter spp. are opportunistic pathogens of environmental origin increasingly isolated in patients with underlying conditions like cystic fibrosis (CF). Despite recent advances, their virulence factors remain incompletely studied, and siderophore production has not yet been investigated this genus. The aim study was to evaluate the siderophores a large collection variability according strain species. A total 163 strains were including 128 clinical (CF non-CF patients) 35 origin. Siderophores quantified by liquid chrome azurol-sulphonate assay. Species identified nrdA gene-based phylogeny. Strains assigned 20 species, xylosoxidans being most represented (51.5% strains). Siderophore observed 72.4% strains, amounts ranging from 10.1% 90% units. significantly higher prevalence siderophore-producing greater for compared Highly variable observations made species: A. presented unique characteristics (one highest producing produced, particularly CF important bacterial growth commonly produced members significance during must be further investigated.
