“…Ralstonia (Di Gioia et al, 2002) and Achromobacter (Pradeep et al, 2015) have been reported as showing the ability of degrading catechol and phthalic acid, respectively, and Delftia have not previously been reported with biodegradation of salicylic acid. The contribution of the other genera with increasing percentages associated with PAHs biodegradation are supported by previous studies for Stenotrophomonas (Zang et al, 2020), Pseudacidovorax (Dealtry et al, 2018), Novosphingobium (Fida et al, 2017), Enterobacter (Lors et al, 2012), Comamonas (Qin et al, 2019), Chryseobacterium (Xiao et al, 2019), and Burkholderia (Morya et al, 2020). After the acclimation that phenanthrene and pyrene were added as carbon source, the dominant genus was Pseudomonas again in sample MBF.…”

Polycyclic aromatic hydrocarbons (PAHs) are highly hard-biodegradable compounds. Therefore, in this work, a multisubstrate enrichment approach was proposed to develop a bacterial community named MBF from activated sludge of coking wastewater plant capable of degrading mixed-PAHs consisting of phenanthrene and pyrene (50 mg/L of each) by 98.8% and 73.3% within 5 days, respectively. The bacterial community could maintain its degradation ability to mixed PAHs relatively under temperatures (20°C–35°C), pH values (5.0–9.0), and salinities (0–10 g/L NaCl). Additionally, the bacterial community MBF degraded 58.9%, 79.9%, and 80.7% of mixed PAHs in the presence of catechol, salicylic acid, and phthalic acid, respectively within 5 days. High-throughput sequencing of 16S rRNA gene amplicon analysis showed that the bacterial community MBF was dominated by Pseudomonas in most treatments, and Burkholderia was predominant under both acidic condition and high salt concentrations. Furthermore, the composition of microbial communities of the bacterial community was significantly different with/without addition of pathway intermediate metabolites after biodegradation of mixed PAHs, revealing the metabolic burden may be distributed between members of this bacterial community. Those results demonstrate that the biodegradation ability of MBF could be maintained with the bacterial community structure altering when facing environmental variations or changes in composition of target contaminants.

A commercial saponin as biosurfactant can reduce the surface tension of water and increase of hydrocarbon degradation. However, this saponin can be toxic to some hydrocarbonoclastic bac-teria. This study aimed to obtain bacterial isolates that were tolerant and incapable to degrade saponin, and to identify them based on 16S rDNA sequence. Bacteria were isolated from petroleum contaminated soil in Wonocolo Village, Bojonegoro Regency, East Java, Indonesia. The soil samples were acclimated using Bushnell-Haas (BH) broth with 0.5% crude oil at room temperature for 3 weeks. The culture was spread onto BH agar incubated at 30°C for 7 days. The first screened, isolates were grown in nutrient broth with addition of sap-onin 0%, 8%, and 12% (v/v) then incubated at 30°C for three days. The bacterial cell density was measured using a spectrophotometer. Second screened, the isolates were grown on BH broth with addition of 0.5% saponin as a sole carbon source, and their cell densities were measured. The selected isolates were identified based on 16S rDNA sequences. Among 34 bacterial isolates, nine isolates were tol-erant to 12% saponin. Three bacterial isolates IHT1.3, IHT1.5, and IHT3.24 tolerant to high concentration of saponin and did not use this substance as growth nutrition. The IHT1.3, IHT1.5, and IHT3.24 isolates were identified as Ochrobactrum pseudogrignonense (99% similarity), Pseudomonas mendocina (99%), and Ochrobactrum pi-tuitosum; (97%), respectively. Those three selected isolates are good candidates as hydrocarbon-degrading bacteria to bioremediation of soil contaminated crude oil. However, the combined activity of bacteria and saponin to degrade hydrocarbon needs further study.

Dealtry et al (2018) scanned the bacterial community of petroleum hydrocarbon degrading consortium inoculated on mangrove tree Avicennia schaueriana for decontamination of artificial petroleum medium.

Nano-bioremediation approach involving the synergistic interaction between indigenous microorganisms and nanoparticles offers an affordable, environmentally, and beneficial solution for wastewater treatment. Herein, environmentally benign, Eichhornia crassipes-mediated green synthesized iron oxide nanoparticles (GS-IONPs) were prepared. The as-prepared GS-IONPs were properly characterized using different spectral analyses. Moreover, a bacterial microbiome was systematically isolated from a wastewater treatment unit located in the natural gas facility, Port Said, Egypt, and grown on a nutrient agar medium. The growth-enhancing effect of GS-IONPs on the bacterial community at different interval periods was studied. Bioremediation activity of employed bacterial consortium towards crude oil was carried out. The outcome data experimentally symbolized that the bacterial consortium was remarkably stable under pH of 7.0 and temperature of 37.0 °C (optimized conditions). Besides, the growth of bacterial consortium was directly proportional to the concentration of GS-IONPs up to the optimum dosage of 0.04 g. Compared to the control sample (non-treated GS-IONPs specimen), the removal % of COD, BOD, and TOC interestingly improved by 74.76, 77.17, and 85.44%, respectively (e.g., 0.04 g of GS-IONPs). Overall, the present study illustrates an ample perspective of nano-bioremediation feasibility as a futuristic rational platform for decontamination of crude oil wastewater using a hydrocarbon-degrading bacterial consortium.
