Bioremediation of Polycyclic Aromatic Hydrocarbons by Means of Bacteria and Bacterial Enzymes

Microorganisms, Journal Year: 2024, Volume and Issue: 12(9), P. 1814 - 1814

Published: Sept. 2, 2024

Polycyclic aromatic hydrocarbons (PAHs) are widespread, persistent, and toxic environmental pollutants. Many anthropogenic some natural factors contribute to the spread accumulation of PAHs in aquatic soil systems. The effective environmentally friendly remediation these chemical compounds is an important challenging problem that has kept scientists busy over last few decades. This review briefly summarizes data on main sources PAHs, their toxicity living organisms, physical approaches PAHs. basic idea behind existing bioremediation outlined with emphasis a detailed description use bacterial strains as individual isolates, consortia, or cell-free enzymatic agents.

Metagenomics-metabolomics analysis of microbial function and metabolism in petroleum-contaminated soil

Brazilian Journal of Microbiology, Journal Year: 2023, Volume and Issue: 54(2), P. 935 - 947

Published: May 10, 2023

Contamination of soil by petroleum is becoming increasingly serious in the world today. However, research on gene functional characteristics, metabolites and distribution microbial genomes oil-contaminated limited. Considering that, metagenomic metabonomic were used to detect microbes soil, changes pathways analyzed. We found that oil pollution significantly changed composition microorganisms metabolites, promoted relative abundance Pseudoxanthomonas, Pseudomonas, Mycobacterium, Immundisolibacter, etc. The degradation toluene, xylene, polycyclic aromatic hydrocarbon fluorobenzoate increased Xenobiotics biodegradation metabolism. Key monooxygenases dioxygenase systems regulated promote ring opening hydrocarbons. Metabolite contents hydrocarbons (PAHs) such as 9-fluoronone gentisic acid significantly. microbiome degraded pollutants into small molecular substances bioremediation petroleum-contaminated soil. Besides, we discovered complete pathway generate from hydroxylation naphthalene PAHs salicylic acid. This study offers important insights aspect regulation mechanism provides a theoretical basis for screening new degrading bacteria.

The persistence and slow rate of natural attenuation genotoxic endocrine-disrupting aromatic pollutants has impacted the soil heath agro-ecologies leading to various health environmental issues. Ecotoxic-xenobiotic compounds degradation property along with plant growth promoting traits microbes are beneficial for devising strategies improved agricultural its clean-up. Present study assessed multipartite promoting-, biocontrol- niche adaptive- five degrading bacteria viz. Pseudomonas bharatica CSV86T, sp. C5pp, PP4, PPD Acinetobacter ISP4. Solubilization rock phosphate (P) feldspar (K), production hormone (auxin; IAA), ammonia, siderophores ACC deaminase by strain C5pp PP4 were observed. Similarly, high fusaric acid resistance (MIC: 1–1.2 mg mL−1) tolerance salinity (5–7.5 %) was In vitro application ISP4 as consortium resulted in significant increase (P < 0.05) seedling shoot length (15–37 %), root (65–150 biomass (30–40 wheat, mung bean fenugreek.

Construction of a Spatial Distribution Relationship Network between Dissolved Organic Matter and Microbial Communities in Chlorobenzene-Polluted Groundwater

ACS ES&T Water, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 2, 2025

Dissolved organic matter (DOM) is an important geochemical feature connecting pollutants and microorganisms in groundwater. However, the patterns of DOM–microbial community interactions caused by spatial distribution differences remain unclear, necessitating construction a correlation network to elucidate relationships between DOM accurately predict biodegradation process pollutants. This study selected chlorobenzene (CBs)-contaminated bioremediation site analyze fluorescent components molecular structures Microbial metabolic activities were more active areas with high CBs concentration, leading significant microbial source contributions DOM. Intense degradation processes accompanied transformation highly oxidized unsaturated Co-occurrence analysis revealed that communities exhibited density, Pseudomonas playing crucial role The constructed DOM–CBs–microbial relationship showed indices, such as O/C, NOSC, CHO (%), strongly correlated structure could directly indicate CBs. characteristics their links provide rapid accurate method monitor contaminated
