“…Some PAHs such as Anthracene, benzo(a)pyrene, phenanthrene, and naphthalene are well-known to produce harmful biological effects such as genotoxicity, mutagenicity, and carcinogenicity and therefore pose a serious threat to the human health (Kim et al, 2013 ; Lin et al, 2020 ). Microorganisms belonging to Sphingomonas, Sphingobium , and Novosphingobium have been found as efficient degrader of PAHs (Lee et al, 2016b ; Fida et al, 2017 ; Auti et al, 2019 ). Rhodococcus, Cunninghamella, Pleurotus ostreatus, Oscillatoria, Agmenellum quadriplicatum, Brevibacterium , and Nocardiodes have been widely shown to metabolize particularly naphthalene and phenanthrene (Ghosal et al, 2016 ; Siles and Margesin, 2018 ).…”

“…This study demonstrated the biodegradation efficiency of microbial consortia with their degradative enzymes and metabolites generated during the remediation process. The microbial-community dynamics of refined- and crude-petroleum-contaminated soil by next-generation sequencing (NGS), and their capability to degrade hydrocarbons and plant-growth-promotion potential through in-silico analysis was investigated by Auti et al ( 2019 ). In this study, 16S rRNA amplicon sequencing on the Illumina MiSeq platform and PICRUSt revealed that both types of soil contained microbial communities with excellent metabolic potential for petroleum hydrocarbon (PHC) degradation.…”

Global environmental contamination with a complex mixture of xenobiotics has become a major environmental issue worldwide. Many xenobiotic compounds severely impact the environment due to their high toxicity, prolonged persistence, and limited biodegradability. Microbial-assisted degradation of xenobiotic compounds is considered to be the most effective and beneficial approach. Microorganisms have remarkable catabolic potential, with genes, enzymes, and degradation pathways implicated in the process of biodegradation. A number of microbes, including Alcaligenes, Cellulosimicrobium, Microbacterium, Micrococcus, Methanospirillum, Aeromonas, Sphingobium, Flavobacterium, Rhodococcus, Aspergillus, Penecillium, Trichoderma, Streptomyces, Rhodotorula, Candida, and Aureobasidium, have been isolated and characterized, and have shown exceptional biodegradation potential for a variety of xenobiotic contaminants from soil/water environments. Microorganisms potentially utilize xenobiotic contaminants as carbon or nitrogen sources to sustain their growth and metabolic activities. Diverse microbial populations survive in harsh contaminated environments, exhibiting a significant biodegradation potential to degrade and transform pollutants. However, the study of such microbial populations requires a more advanced and multifaceted approach. Currently, multiple advanced approaches, including metagenomics, proteomics, transcriptomics, and metabolomics, are successfully employed for the characterization of pollutant-degrading microorganisms, their metabolic machinery, novel proteins, and catabolic genes involved in the degradation process. These technologies are highly sophisticated, and efficient for obtaining information about the genetic diversity and community structures of microorganisms. Advanced molecular technologies used for the characterization of complex microbial communities give an in-depth understanding of their structural and functional aspects, and help to resolve issues related to the biodegradation potential of microorganisms. This review article discusses the biodegradation potential of microorganisms and provides insights into recent advances and omics approaches employed for the specific characterization of xenobiotic-degrading microorganisms from contaminated environments.

“…The resultant FTIR spectrum ( Figure 5) has exhibited several absorption bands that correspond to the functional groups of the biomolecules existing in the plant extract. Five main absorption peaks were observed, the broad peak centered at 3340 cm -1 is assigned to O-H stretching vibrations 6 , the intense peak at 1650 cm -1 is due to C=O stretching and N-H bending vibrations of primary amides group which is commonly found in the protein 26 . The two peaks located at 1364 cm -1 and 1204 cm -1 are assigned to the nitro banding N-O vibrations and C-O-C stretching vibrations of the aromatic ring respectively 27 .…”

In this study, green synthesis of silver /silver oxide nanoparticles was successfully prepared from Phoenix Dactylifera L aqueous leaves extract. The effect of different volume ratio (% v/v) (Plant extract / Precursor) on the nanoparticles silver /silver oxide nanoparticles formation, optical properties, and catalytic activity for dye degradation was studied. The obtained Ag/Ag2O nanoparticles were characterized using various techniques, such as UV-Visible, FT-IR, XRD, SEM for this purpose. The UV-Vis spectrum shows the absorption at 430 nm associated with Ag/Ag2O NPs. The optical bandgap values were found to be in the range of 3.22 to 4.47 eV for the direct bandgap and 3.73 to 5.23 eV for the indirect bandgap. The functional groups present in plant extracts were studied by FTIR. XRD confirmed the crystalline nature of Ag / Ag2O NP, and its average particle size was between 28.66-39.40 nm. SEM showed that the green synthesized silver/silver oxide nanoparticles have a spherical shape. The purpose of this study, it highlights the high catalytic activity for dye degradation of Ag/Ag2O NPs green synthesized. As a result, the use of Phoenix Dactylifera L aqueous leaves extract offers a cost-effective and eco-friendly method.

“…In addition to the selection of populations that can decompose hydrocarbons occurring after petroleum pollution, microbial community successions in contaminated soils are determined by the initial soil microbial composition, as well as by the soil's physicochemical properties and oil concentration 17,18,20,30 . The initial microbial composition is mainly influenced by the soil organic carbon content, pH, moisture and oxygen content, climate conditions, geographic position and soil genesis, and plants 19,[31][32][33][34][35][36][37][38][39] . Particle size, clay content, and organic matter content are the main factors affecting the sorption and desorption of hydrocarbons in soil particles that, in turn, affect their toxicity and bioavailability [40][41][42] .…”

Petroleum pollution of soils is a major environmental problem. Soil microorganisms can decompose a significant fraction of petroleum hydrocarbons in soil at low concentrations (1–5%). This characteristic can be used for soil remediation after oil pollution. Microbial community dynamics and functions are well studied in cases of moderate petroleum pollution, while cases with heavy soil pollution have received much less attention. We studied bacterial and fungal successions in three different soils with high petroleum contents (6 and 25%) in a laboratory experiment. The proportion of aliphatic and aromatic compounds decreased by 4–7% in samples with 6% pollution after 120 days of incubation but remained unchanged in samples with 25% hydrocarbons. The composition of the microbial community changed significantly in all cases. Oil pollution led to an increase in the relative abundance of bacteria such as Actinobacteria and the candidate TM7 phylum (Saccaribacteria) and to a decrease in that of Bacteroidetes. The gene abundance (number of OTUs) of oil-degrading bacteria (Rhodococcus sp., candidate class TM7-3 representative) became dominant in all soil samples, irrespective of the petroleum pollution level and soil type. The fungal communities in unpolluted soil samples differed more significantly than the bacterial communities. Nonmetric multidimensional scaling revealed that in the polluted soil, successions of fungal communities differed between soils, in contrast to bacterial communities. However, these successions showed similar trends: fungi capable of lignin and cellulose decomposition, e.g., from the genera Fusarium and Mortierella, were dominant during the incubation period.
