ABSTRACT Phenanthrene (PHEN), a polycyclic aromatic hydrocarbon (PAH), is degraded by white-rot fungi like Phanerochaete chrysosporium (the fungus has been renamed as Phanerodontia ). PHEN metabolized P. and transformed into various monohydroxylated dihydroxylated products. These intermediates are further cleavage of the ring. However, enzymes involved in conversion remain largely unidentified. We aimed to identify characterize degradation its intermediates. Recombinant flavoprotein monooxygenase 11 (FPMO11), homolog salicylate 1-monooxygenase from naphthalene-degrading bacterium Pseudomonas putida G7, was overexpressed Escherichia coli . FPMO11 catalyzes oxidative decarboxylation 1-hydroxy-2-naphthoate (1H2N) 2-hydroxy-1-naphthoate (2H1N) 1,2-dihydroxynaphthalene (1,2DHN). To best our knowledge, this first study with 1H2N 2H1N activities members FPMO superfamily. Additionally, search for dioxygenase ability catalyze ring 1,2DHN led identification intradiol (IDD) 1 IDD2 , which 1,2DHN. Thus, also identified, time, activity IDD The findings highlight unique substrate spectra IDDs, rendering them attractive candidates biotechnological applications, especially mitigation environmental health risks associated PAH pollution.

This could help reduce pollution mitigate exposure. potential these applications highlighted, emphasizing their critical role understanding fungi.

Chemical exposure in the environment can adversely affect biodiversity of living organisms, particularly when persistent chemicals accumulate over time and disrupt balance microbial populations. In this study, we examined how chemical contaminants influence microorganisms sediment overlaying water samples collected from Kinnickinnic, Milwaukee, Menomonee Rivers near Wisconsin, USA. We characterized these using shotgun metagenomic sequencing to assess microbiome diversity employed analyses quantify more than 200 compounds spanning 16 broad classes, including pesticides, industrial products, personal care pharmaceuticals. Integrative differential comparative combined datasets revealed that density, approximated by adjusted total sequence reads, declined with increasing concentrations. Protozoan, metazoan, fungal populations were negatively correlated higher concentrations, whereas certain bacterial (particularly Proteobacteria) archaeal showed positive correlations. As expected, exhibited concentrations a wider dynamic range compared samples. Varying levels contamination appeared shape distribution taxa, some bacterial, protozoan present only at sites or specific sample types (sediment versus water). These findings suggest may be linked both type concentration present. Additionally, study demonstrates potential roles multiple kingdoms degrading environmental pollutants, emphasizing metabolic versatility bacteria archaea processing complex such as polyaromatic hydrocarbons bisphenols. Through functional resistance gene profiling, observed multi-kingdom consortia—including bacteria, fungi, protozoa—can contribute bioremediation strategies help restore ecological contaminated ecosystems. This approach also serve valuable proxy for assessing well their effects on biodiversity.

Polycyclic aromatic hydrocarbons (PAHs) are pervasive organic pollutants in the environment that formed as an outcome of partial combustion matter. PAHs pose a significant threat to ecological systems and human health due their cytotoxic genotoxic effects. Therefore, immediate need for effective PAH remediation methods is crucial. Although nanomaterials PAHs, concerns regarding environmental compatibility sustainability remains. this study emphasizes integration with bioremediation methods, which might offer more sustainable ecofriendly approach remediation. A systematic search was conducted through scholarly databases from 2013 2023. total 360 articles were scrutinized, among 26 selected resonated application nano-bioremediation. These literatures comprise both comparative analysis only well There elevation 18.9 % removal liquid-phase samples, when comparing (52.2 %) nano-bioremediation (71.1 %). consistent trend observed soil successfully remove 60.8 75.1 respectively, indicating 14.3 improvement. Furthermore, review elaborated on various features led efficiency PAH. The also discussed strategies namely nanomaterial-assisted microbial degradation, enzyme-enhanced activity, nanomaterial-immobilized cells, nanomaterial-facilitated electron transfer, even some eco-green approaches remediate like biogenic nanomaterial PAHs.

The bioremediation of polycyclic aromatic hydrocarbon (PAHs) from soil utilizing microorganisms, enzymes, microbial consortiums, strains, etc. has attracted a lot interest due to the environmentally friendly, and cost-effective features. Enzymes can efficiently break down PAHs in by hydroxylating benzene ring, breaking C-C bond, catalyze hydroxylation variety ring compounds via single-electron transfer oxidation. However, practical application is limited its instability ease loss function under harsh environmental conditions such as pH, temperature, edaphic stress Therefore, this paper focused on techniques used immobilize enzymes remediate soil. Moreover, previous research not adequately covered topic, despite employment several immobilized aqueous solution cultures other types organic pollutants. Bibliometric analysis further highlighted trends 2000 2023 field growing identified important challenges regarding enzyme stability interaction with matrices. findings indicated that may catalyzed oxidation OH groups rings, generate benzyl radicals (i.e.,
