Metagenomics: an emerging tool for the chemistry of environmental remediation

Frontiers in Environmental Chemistry, Journal Year: 2023, Volume and Issue: 4

Published: May 9, 2023

Metagenomics is the study of genetic information, including sequences and genomes microorganisms present in an environment. Since 1998, full-scale application this technique to environmental chemistry has brought significant advances characterization nature chemical composition/distribution contaminants matrices contaminated and/or remediated sites. This been critical selection contributed significantly success biological treatment over years. gone through different phases development, which ranges from initial sequencing strategies next-generation (NGS), a recently developed technology obtain more robust deoxyribonucleic acid (DNA) profile devoid chimeric reduces quality metagenomic data. Therefore, objective review evaluate applications metagenomics understanding dynamics during remediation studies. Also, presents relationship between characteristics properties compounds, forms basis bioremediation could be useful developing predictive models that enhance efficiency. In conclusion, techniques have improved characterisation environment provides correlation for prediction type contaminant expected various matrices.

Diversity and metagenome analysis of a hydrocarbon-degrading bacterial consortium from asphalt lakes located in Wietze, Germany

AMB Express, Journal Year: 2021, Volume and Issue: 11(1)

Published: June 14, 2021

The pollution of terrestrial and aquatic environments by petroleum contaminants, especially diesel fuel, is a persistent environmental threat requiring cost-effective environmentally sensitive remediation approaches. Bioremediation one such approach, but dependent on the availability microorganisms with necessary metabolic abilities adaptability. aim this study was to examine microbial community in contaminated site, isolate organisms potentially able degrade hydrocarbons. Through successive enrichment soil from samples an historic site Wietze, Germany, we isolated bacterial consortium using fuel hydrocarbons as sole carbon energy source. 16S rRNA gene analysis revealed dominance Alphaproteobacteria. We further reconstructed total 18 genomes both original sample consortium. metagenome metagenome-assembled show that most abundant genus consortium, Acidocella, possess many genes required for degradation aromatic hydrocarbons, which are often toxic component. This can explain why proliferated all cultures. Therefore, reveals its dominant genus, could serve effective inoculum bioremediation sites polluted or other organic contaminants.

Salicylate or Phthalate: The Main Intermediates in the Bacterial Degradation of Naphthalene

Processes, Journal Year: 2021, Volume and Issue: 9(11), P. 1862 - 1862

Published: Oct. 20, 2021

Polycyclic aromatic hydrocarbons (PAHs) are widely presented in the environment and pose a serious environmental threat due to their toxicity. Among PAHs, naphthalene is simplest compound. Nevertheless, its high toxicity presence waste of chemical oil processing industries, one most critical pollutants. Similar other released into via incomplete combustion organic compounds, pyrolysis, spills, processing, household disposal, use fumigants deodorants. One main ways detoxify such compounds natural through microbial degradation. For first time, pathway degradation was investigated pseudomonades. The salicylate found be key intermediate. some this considered main, if not only one, bacterial destruction naphthalene. However, later, data emerged which indicated that gram-positive bacteria overwhelming majority cases capable formation/destruction salicylate. obtained made it possible reveal protocatechoate, phthalate, cinnamic acids predominant intermediates by rhodococci. Pathways degradation, enzymes, genetic regulation subjects present review, representing an attempt summarize current knowledge about mechanism PAHs. Modern molecular methods also discussed context development “omics” approaches, namely genomic, metabolomic, proteomic, used as tools for studying mechanisms biodegradation. Lastly, comprehensive understanding formation specific ecosystems provided.
