Chakravarty P, Deka H, Chowdhury D. Green titanium dioxide (TiO 2) nanoparticles assisted biodegradation of anthracene employing Serratia quinivorans HP5. J Basic Microbiol 2024; 64:e2300680. [PMID: 38381060 DOI: 10.1002/jobm.202300680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 12/28/2023] [Accepted: 02/03/2024] [Indexed: 02/22/2024]
Abstract
The anthracene biodegradation potential of Serratia quinivorans HP5 was studied under a controlled laboratory environment. The green TiO2 nanoparticles (NPs) synthesized from Paenibacillus sp. HD1PAH was used to accelerate the biodegradation process. The synergistic application of TiO2 NPs and S. quinivorans HP5 resulted in a reduction of anthracene concentration by 1.2 folds in liquid-medium and 1.5 folds in contaminated soil. Gas-chromatography and mass-spectrometric investigation showed the production of four anthracene derivatives, namely 1,2-anthracene dihydrodiol, 6,7-benzocoumarin, anthrone, and 9,10-anthraquinoneat the termination of experimental periods. Furthermore, bacterial biomass increased by 23.3 folds in the presence of TiO2 NPs, and overall soil enzyme activities were enhanced by 4.2 folds in the treated samples. In addition, there was a negative correlation observed between the biomass of S. quinivorans HP5 and the concentrations of anthracene, suggesting the involvement of bacterium in anthracene biodegradation processes. The degradation pathway of anthracene revealed its transformation into the less toxic compound 9,10-anthraquinone. Overall, this study elucidates a novel biodegradation pathway for anthracene and highlights the potential of nano-assisted bacterial remediation as a promising approach for environmental cleanup.

CHEMOSPHERE 2023; 321:138102. [PMID: 36764617 DOI: 10.1016/j.chemosphere.2023.138102] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 02/07/2023] [Accepted: 02/08/2023] [Indexed: 06/18/2023]
Abstract
Anthracene biodegradation potential has been studied in liquid culture and soil microcosm environment by employing green synthesized TiO2 nanoparticles (NPs) and Alcaligenes faecalis HP8. The bacterium was isolated from crude oil contaminated soil, while TiO2 nanoparticles were synthesized using Paenibacillus sp. HD1PAH and Cyperus brevifolius which have PAHs remediation abilities. The dual application of TiO2 nanoparticles and Alcaligenes faecalis HP8 decreases anthracene concentration up to 21.3% in liquid at the end of 7 days and 37.9% in the soil treatments after completion of 30 days. Besides, the GC-MS analysis revealed production of five metabolites including 1,2-anthracenedihydrodiol; 6,7-benzocoumarin; 3-hydroxy-2-naphthoic acid; salicylic acid and 9,10-anthraquinone at different time interval of the treatments. Anthracene degradation pathway confirms the breakdown of three ring anthracene to one ring salicylic acid. Additionally, soil dehydrogenase, urease, alkaline phosphatase, catalase and amylase activities increased up to 4.09 folds, 8.6 folds, 4.4 folds, 3.6 folds and 2.1 folds respectively after the combined treatments of TiO2 nanoparticles and Alcaligenes faecalis HP8. The bacterial biomass and residual anthracene concentration were found to be negatively correlated. Finally, the study brings into light a novel anthracene biodegradation pathway and provides a new dimension in nano assisted bacterial remediation.

Analysis of phenanthrene degradation by Ascomycota fungi isolated from contaminated soil from Reynosa, Mexico. Lett Appl Microbiol 2021; 72:542-555.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) are organic compounds generated mainly by anthropogenic sources. They are considered toxic to mammals, since they have carcinogenic, mutagenic and genotoxic properties, among others. Although mycoremediation is an efficient, economical and eco-friendly technique for degrading PAHs, the fungal degradation potential of the phylum Ascomycota has not been widely studied. In this work, we evaluated different fungal strains from the polluted soil of 'La Escondida' lagoon in Reynosa, Mexico to know their potential to degrade phenanthrene (PHE). Forty-three soil isolates with the capacity to grow in the presence of PHE (0·1% w/v) were obtained. The fungi Aspergillus oryzae MF13 and Aspergillus flavipes QCS12 had the best potential to degrade PHE. Both fungi germinated and grew at PHE concentrations of up to 5000 mg l-1 and degraded 235 mg l-1 of PHE in 28 days, with and without an additional carbon source. These characteristics indicate that A. oryzae MF13 and A. flavipes QCS12 could be promising organisms for the remediation of sites contaminated with PAHs and detoxification of recalcitrant xenobiotics.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2020; 746:140455. [PMID: 32758981 DOI: 10.1016/j.scitotenv.2020.140455] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 06/18/2020] [Accepted: 06/21/2020] [Indexed: 05/15/2023]
Abstract
Polycyclic aromatic hydrocarbons (PAHs) are typical persistent organic pollutants that accumulate in the environment, mainly from anthropogenic activities. Microbial degradation is the main pathway of PAHs degradation in the natural environment. Therefore, the widen of the available bank of microbial resources and exploration of the molecular degradation mechanisms of PAHs are crucial to the proper management of PAHs-polluted sites. In this work, a bacterial strain, YM-6, which has a high ability to utilize phenanthrene (PHE) as its sole source of carbon and energy, was isolated from sediment contaminated with PAHs. The strain YM-6 was found to degrade 96.3% of 100 mg/L of PHE in liquid cultures within 52 h. The strain was identified as Diaphorobacter sp. by 16S rDNA sequencing. The optimum growth conditions of the YM-6 strain were studied, and the results indicated that the optimum growth temperature of the strain was 30 °C, and the optimum growth pH was 7. The stain is well-suited for high-temperature stress (40 °C), and it could withstand 400 mg/L of PHE. The strain's PHE metabolism was assayed using GC-MS analyses. The results revealed that the YM-6 strain metabolized PHE via the phthalic acid pathway because the intermediates, such as phthalic acid, diethyl ester and phthalaldehydic acid, methyl ester, were detected. The use of this strain may be an attractive alternative for the bioremediation of polycyclic aromatic hydrocarbons in an aquatic environment.
