Global Geographic Patterns of Soil Microbial Degradation Potential for Polycyclic Aromatic Hydrocarbons

Polycyclic aromatic hydrocarbons (PAHs) are toxic and persistent pollutants that widely distributed in the environment. PAHs to microorganisms pose ecological risks. Bacteria encode enzymes for PAH degradation through specific genes, thereby mitigating pollution. However, due PAHs' complexity, information on global potential, diversity, associated risks of PAH-degrading microbes soils is lacking. In this study, we analyzed 121 genes selected 33 as marker predict potential within soil microbiome. By constructing a Hidden Markov Model, identified 4990 species carrying 40,039 metagenomic assembly genomes, with Burkholderiaceae Stellaceae emerging high-potential degraders. We demonstrated candidate degraders predominantly emerged artificial farmland, significantly fewer present extreme environments, driven by factors such average annual rainfall, organic carbon, human modification terrestrial systems. Furthermore, comprehensively quantified each host future practical applications using three indicators (antibiotic resistance virulence factors, pathogenic bacteria). found degrader has significant application prospects. Our research will help determine biosynthetic globally further identify bacteria at lower risk.

An organic O donor for biological hydroxylation reactions

Proceedings of the National Academy of Sciences, Год журнала: 2024, Номер 121(13)

Опубликована: Март 20, 2024

All biological hydroxylation reactions are thought to derive the oxygen atom from one of three inorganic donors, O 2 , H 2, or O. Here, we have identified organic compound prephenate as donor for steps -independent biosynthetic pathway ubiquinone, a widely distributed lipid coenzyme. Prephenate is an intermediate in aromatic amino acid and genetic experiments showed that it essential ubiquinone biosynthesis Escherichia coli under anaerobic conditions. Metabolic labeling with 18 O-shikimate, precursor prephenate, demonstrated incorporation atoms into ubiquinone. The role specific iron–sulfur enzymes belonging widespread U32 protein family discussed. Prephenate-dependent represent unique biochemical strategy adaptation environments.

A numerical approach assisted by machine learning was developed for screening and optimizing soil remediation strategies. The includes a reactive transport model simulating the cost effect of applicable technologies their combinations target site. simulated results were used to establish relationship between using method. then an optimization method provide optimal strategies under various constraints requirements evaluated site contaminated with both arsenic polycyclic aromatic hydrocarbons at former shipbuilding factory in Guangzhou City, China. An strategy obtained successfully implemented site, which included partial excavation soils natural attenuation residual soils. advantage is that it can fully consider capacity designing reduce costs cost-effective variable policymakers. general be applied other sites.
