Global environmental contamination with a complex mixture of xenobiotics has become major issue worldwide. Many xenobiotic compounds severely impact the environment due to their high toxicity, prolonged persistence, and limited biodegradability. Microbial-assisted degradation is considered be most effective beneficial approach. Microorganisms have remarkable catabolic potential, genes, enzymes, pathways implicated in process biodegradation. A number microbes, including Alcaligenes, Cellulosimicrobium, Microbacterium, Micrococcus, Methanospirillum, Aeromonas, Sphingobium, Flavobacterium, Rhodococcus, Aspergillus, Penecillium, Trichoderma, Streptomyces, Rhodotorula, Candida, Aureobasidium, been isolated characterized, shown exceptional biodegradation potential for variety contaminants from soil/water environments. potentially utilize as carbon or nitrogen sources sustain growth metabolic activities. Diverse microbial populations survive harsh contaminated environments, exhibiting significant degrade transform pollutants.

Lignin modifying enzymes from fungi and bacteria are potential biocatalysts for sustainable mitigation of different potentially toxic pollutants in wastewater. Notably, the paper pulp industry generates enormous amounts wastewater containing high complex lignin-derived chlorinated phenolics sulfonated pollutants. The presence these compounds is a critical issue environmental toxicological perspectives. Some chloro-phenols harmful to environment human health, as they exert carcinogenic, mutagenic, cytotoxic, endocrine-disrupting effects. In order address most urgent concerns, use oxidative lignin bioremediation has come into focus. These catalyze modification phenolic non-phenolic substances, include laccase range peroxidases, specifically peroxidase (LiP), manganese (MnP), versatile (VP), dye-decolorizing (DyP). this review, we explore key pollutant-generating steps processing, summarize recently reported effects industrial compounds, especially pollutants, outline approaches pollutant industry, emphasizing catalytic regard. We highlight other emerging biotechnical approaches, including phytobioremediation, bioaugmentation, Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-based technology, protein engineering, degradation pathways prediction, that currently gathering momentum Finally, current research needs options maximizing biobased biocatalytic

Bacteria, Fungi and Microalgae for the Bioremediation of Marine Sediments Contaminated by Petroleum Hydrocarbons in the Omics Era

Microorganisms, Journal Year: 2021, Volume and Issue: 9(8), P. 1695 - 1695

Published: Aug. 10, 2021

Petroleum hydrocarbons (PHCs) are one of the most widespread and heterogeneous organic contaminants affecting marine ecosystems. The contamination sediments or coastal areas by PHCs represents a major threat for ecosystem human health, calling urgent, effective, sustainable remediation solutions. Aside from some physical chemical treatments that have been established over years sediment reclamation, bioremediation approaches based on use microorganisms gaining increasing attention their eco-compatibility, lower costs. In this work, we review current knowledge concerning in systems, presenting synthesis effective microbial taxa (i.e., bacteria, fungi, microalgae) identified so far hydrocarbon removal. We also discuss challenges offered innovative molecular design reclamation strategies these three components contaminated hydrocarbons.

How to sustainably feed a growing global population is question still without an answer. Particularly farmers, increase production, tend apply more fertilizers and pesticides, trend especially predominant in developing countries. Another challenge that industrialization other human activities produce pollutants, which accumulate soils or aquatic environments, contaminating them. Not only well-being at risk, but also environmental health. Currently, recycling, land-filling, incineration pyrolysis are being used reduce the concentration of toxic pollutants from contaminated sites, too have adverse effects on environment, producing even resistant highly intermediate compounds. Moreover, these methods expensive, difficult execute for soil, water, air decontamination. Alternatively, green technologies currently developed degrade pollutants. This review provides overview current research microbial inoculation as way either replace use agrochemicals clean environments heavily affected by pollution. Microorganism-based inoculants enhance nutrient uptake, promote crop growth, protect plants pests diseases can food production. Several examples how biofertilizers biopesticides production discussed. Plant roots be colonized variety favourable species genera plant growth. Microbial interventions sites accumulated heavy metals, polyaromatic hydrocarbons, industrial effluents.

The oxidation of hydrocarbons by diverse heterotrophic and mixotrophic bacteria that inhabit deep-sea hydrothermal ecosystems

The ISME Journal, Journal Year: 2020, Volume and Issue: 14(8), P. 1994 - 2006

Published: April 30, 2020

Abstract Hydrothermal activity can generate numerous and diverse hydrocarbon compounds. However, little is known about the influence of such hydrocarbons on deep-sea hydrothermal microbial ecology. We hypothesize that certain bacteria live these hydrocarbons. Therefore, in this study, distribution their associated hydrocarbon-degrading were investigated at vents Southern Mid-Atlantic Ridge, Southwest Indian East Pacific Rise. A variety consortia obtained from samples collected aforementioned sites after low-temperature enrichment under high hydrostatic pressures, responsible for degradation by DNA-based stable-isotope probing with uniformly 13C-labeled Unusually, we identified several previously recognized sulfur-oxidizing chemoautotrophs as bacteria, e.g., SAR324 group, SUP05 clade, Sulfurimonas, first time confirmed ability to degrade In addition, Erythrobacter, Pusillimonas, SAR202 clade shown polycyclic aromatic time. These results together relatively abundance situ most above-described highlight potential configuring vent community, have made importance mixotrophs ecosystems evident.
