“…Biological treatment of wastewater is advantageous over physical-chemical treatment because of its low cost, environmentally friendly approach and the ability of using microbial enzymes and biosurfactants in degrading (converting) organic pollutants into harmless substances (Wang and Fingas 1995;El-Bestawy et al 1998;El Bestawy et al 2014;Crini and Lichtfouse 2019;Liu et al 2019b). Immobilized (fixed) microbial cells are preferred than suspended cells due to their operational stability against adverse environmental conditions (temperature and pH), high mechanical strength, high metabolic activity, easier separation and the ability to be reused (Hou et al 2016;Katam and Bhattacharyya 2019).…”

The study aimed to investigate the efficiency of exogenous bacterial consortium (Enterobacter cloacae and Pseudomonas otitidis) decorated (immobilized) with Fe 3 O 4 Nanoparticles for the treatment of petroleum hydrocarbon-contaminated wastewater. Glycine coated magnetite Nanoparticles (Fe 3 O 4 NPs) were prepared using reverse co-precipitation method and were characterized using X-ray diffraction, transmission and scanning electron microscopy and vibrating sample magnetometer. They were used to decorate exogenous bacterial consortium (Enterobacter cloacae and Pseudomonas otitidis) at 3 different Fe 3 O 4 /bacteria ratios (1:1, 1:3 and 3:1 w/w). Bioremediation of oil contaminated wastewater collected from one of the petroleum distribution companies, Alexandria was conducted for 168 h using Fe 3 O 4 /bacterial association at the best ratio (3:1) and compared with non-decorated consortium and the indigenous bacteria in the control. Analysis indicated crystalline structure of Fe 3 O 4 NPs with spherical particles (size: 15-20 nm) and superparamagnetic properties. Glycine modified-Fe 3 O 4 exhibited high ability to immobilize bacteria which acquired its magnetic properties. The highest coating efficiency (92%) was achieved at 3:1 Fe 3 O 4 /bacteria ratio after 1 h. This ratio positively affected bacterial growth reaching the highest growth rate (5.07 fold higher than the control) after 4 h. The highest removal efficiencies of the total suspended solids (TSS), chemical oxygen demands (COD), oil and grease (O&G) and total petroleum hydrocarbons (TPH) recording 96, 65.4, 83.9 and 85% reaching residual concentrations of 9.5, 598, 99 and 60 mg/l respectively were achieved after 4 h by the Fe 3 O 4-bacteria assembly. Compared with the maximum permissible limits of the tested parameters, TSS residue was highly compiled with its limit (50 mg/l), while COD, O&G and TPH were 7.5, 9.9, and 120-folds higher than their limits (100, 15 and 0.5 mg/l respectively). To the best of our knowledge it is first time to use integrated Enterobacter cloacae and Pseudomonas otitidis consortium decorated with Fe 3 O 4 NPs for the treatment of petroleum hydrocarbon-contaminated wastewater. The proposed system proved to be a very efficient, economical and applicable for the removal of the included contaminants in very short running time which increases its biotechnological added value.

“…A. baumannii is abundant in nature, and can be acquired from water, soil and living organisms. Some strains of Acinetobacter are known to be associate in biodegradation of different number of pollutants such as Permethrin (Zhan et al 2018 ), phenanthrene, 3-chloroaniline (Duc 2016 ), diesel (Ho et al 2020 ), indole (Sadauskas et al 2017 ), malathion (Xie et al 2009 ), deltamethrin (Tang et al 2020 ), azo dye (Sreedharan et al 2021 ) and phenol (Liu et al 2020 ). Biodegradation of cellulose, chitin, pectin, fluoranthene, and phenanthrene by Actinetobacter from deep Sea Sediments were reported by (Chen et al 2016 ).…”

Ciprofloxacin (CIP) and levofloxacin (LEV), widely used fluoroquinolone antibiotics, are often found in sewage from the sewage treatment plants and marine environment. In this study, CIP and LEV biodegrading bacterial consortia were obtained from industrial wastewater. Microorganisms in these consortia were identified as Acinetobacter baumannii (A. baumannii), Klebsiella pneumoniae (K. pneumoniae) and Elizabethkingia miricola (E. miricola). The impacts of the critical operating parameters on the elimination of CIP and LEV by bacterial consortia have been investigated and optimized to achieve the maximum levels of CIP and LEV biodegradation. Using liquid chromatography with tandem mass spectrometry (LC-MS-MS), possible degradation pathways for CIP and LEV were suggested by analyzing the intermediate degradation products. The role of the enzymes fluoroquinolone-acetylating aminoglycoside (6′-N-acetyltransferase) and cytochrome P450 (CYP450) in the breakdown of fluoroquinolones (FQs) was investigated as well. According to our findings, various biodegradation mechanisms have been suggested, including cleavage of piperazine ring, substitution of F atom, hydroxylation, decarboxylation, and acetylation, as the main biotransformation reactions. This study discovers the ability of non-reported bacterial strains to biodegrade both CIP and LEV as a sole carbon source, providing new insights into the biodegradation of CIP and LEV.

“…Additionally, phenolic compounds can result from degradation of natural organic matter in the environment, e.g., from the decomposition of plants and animals (Anku et al, 2017), and are thus ubiquitous in the environment. A number of mesophilic bacteria and yeasts can degrade phenol, e.g., Acinetobacter radioresistens, Glutamicibacter nicotianae, and Candida subhashii (Filipowicz et al, 2017;Duraisamy et al, 2020;Liu et al, 2020). The mechanism of phenol degradation in mesophilic microorganisms has been thoroughly studied because of their application in bioremediation.…”

Utilization of Phenol as Carbon Source by the Thermoacidophilic Archaeon Saccharolobus solfataricus P2 Is Limited by Oxygen Supply and the Cellular Stress Response

Present in many industrial effluents and as common degradation product of organic matter, phenol is a widespread compound which may cause serious environmental problems, due to its toxicity to animals and humans. Degradation of phenol from the environment by mesophilic bacteria has been studied extensively over the past decades, but only little is known about phenol biodegradation at high temperatures or low pH. In this work we studied phenol degradation in the thermoacidophilic archaeon Saccharolobus solfataricus P2 (basonym: Sulfolobus solfataricus) under extreme conditions (80°C, pH 3.5). We combined metabolomics and transcriptomics together with metabolic modeling to elucidate the organism’s response to growth with phenol as sole carbon source. Although S. solfataricus is able to utilize phenol for biomass production, the carbon source induces profound stress reactions, including genome rearrangement as well as a strong intracellular accumulation of polyamines. Furthermore, computational modeling revealed a 40% higher oxygen demand for substrate oxidation, compared to growth on glucose. However, only 16.5% of oxygen is used for oxidation of phenol to catechol, resulting in a less efficient integration of carbon into the biomass. Finally, our data underlines the importance of the phenol meta-degradation pathway in S. solfataricus and enables us to predict enzyme candidates involved in the degradation processes downstream of 2-hydroxymucconic acid.
