Microbial Degradation of Naphthalene and Substituted Naphthalenes: Metabolic Diversity and Genomic Insight for Bioremediation

Frontiers in Bioengineering and Biotechnology, Journal Year: 2021, Volume and Issue: 9

Published: March 9, 2021

Low molecular weight polycyclic aromatic hydrocarbons (PAHs) like naphthalene and substituted naphthalenes (methylnaphthalene, naphthoic acids, 1-naphthyl N -methylcarbamate, etc.) are used in various industries exhibit genotoxic, mutagenic, and/or carcinogenic effects on living organisms. These synthetic organic compounds (SOCs) or xenobiotics considered as priority pollutants that pose a critical environmental public health concern worldwide. The extent of anthropogenic activities emissions from coal gasification, petroleum refining, motor vehicle exhaust, agricultural applications determine the concentration, fate, transport these ubiquitous recalcitrant compounds. Besides physicochemical methods for cleanup/removal, green eco-friendly technology bioremediation, using microbes with ability to degrade SOCs completely convert non-toxic by-products, has been safe, cost-effective, promising alternative. Various bacterial species soil flora belonging Proteobacteria ( Pseudomonas , Pseudoxanthomonas Comamonas Burkholderia Novosphingobium ), Firmicutes Bacillus Paenibacillus Actinobacteria Rhodococcus Arthrobacter ) displayed SOCs. Metabolic studies, genomic metagenomics analyses have aided our understanding catabolic complexity diversity present simple life forms which can be further applied efficient biodegradation. prolonged persistence PAHs led evolution new degradative phenotypes through horizontal gene transfer genetic elements plasmids, transposons, phages, islands, integrative conjugative elements. Systems biology engineering either specific isolates mock community (consortia) might achieve complete, rapid, bioremediation synergistic actions. In this review, we highlight metabolic routes diversity, makeup cellular responses/adaptations by naphthalene-degrading bacteria. This will provide insights into ecological aspects field application strain optimization bioremediation.

New Frontiers of Anaerobic Hydrocarbon Biodegradation in the Multi-Omics Era

Frontiers in Microbiology, Journal Year: 2020, Volume and Issue: 11

Published: Nov. 16, 2020

The accumulation of petroleum hydrocarbons in the environment substantially endangers terrestrial and aquatic ecosystems. A number microbial strains have been recognised to utilize aliphatic aromatic under aerobic conditions. Nevertheless, most these pollutants are transferred by natural processes, including rain, into underground anaerobic zones where their degradations much more problematic. Even though bioremediation has well-characterized over past few decades, ample research is yet be done field hydrocarbon biodegradation. With emergence high-throughput techniques, known as omics (e.g. genomics metagenomics), individual biodegraders, hydrocarbon-degrading communities metabolical pathways could specified. Our objective review biodegradation important degraders diverse metabolic use various terminal electron acceptors; describe divergent activation reactions; outline key components so far; explain interactions between community members; provide a short outlook for effective applications technologies.
