Synergistic effects of a functional bacterial consortium on enhancing phenanthrene biodegradation and counteracting rare earth biotoxicity in liquid and slurry systems

Abstract: Significance and Impact of the Study: This study focused on the effect of rare earth (REs) on the biodegradation of polycyclic aromatic hydrocarbons (PAHs). The RE ions Ce 3+ and Y 3+ inhibited Moraxella osloensis CFP312 from degrading phenanthrene without affecting its glucose utilization. This inhibition effect can be relieved through co-cultivation with Bacillus subtilis MSP117, which has high adsorption capacity for RE ions in liquid and slurry systems. MSP117 adsorbed and fixed RE ions on its cell surface… Show more

“…Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants posing significant threats due to their carcinogenicity and mutagenicity . This concern is reflected in the U.S. Environmental Protection Agency’s inclusion of 16 PAHs on its priority pollutant list . Their hydrophobic nature leads to persistence in nonaqueous-phase liquids (NAPLs) like coal tar, creosote, and leaked petroleum, further increasing their environmental threat .…”

“…1 This concern is reflected in the U.S. Environmental Protection Agency's inclusion of 16 PAHs on its priority pollutant list. 2 Their hydrophobic nature leads to persistence in nonaqueous-phase liquids (NAPLs) like coal tar, creosote, and leaked petroleum, further increasing their environmental threat. 3 While crude oil represents a natural source of PAHs, oil spills introduce acute hydrocarbon pollution, with PAHs constituting 3−30% of spilled oil depending on the type.…”

“…However, the occurrence of organic pollutants such as hydrocarbons inhibits plant growth and ultimately the population and performance of plant-associated indigenous microorganisms. To overcome this issue, the augmentation of microorganisms capable of degrading pollutants, and with plant growth-promoting (PGP) activities, has been employed in FTWs and CWs to improve the phytoremediation process [23,25,26]. Although bacterial-augmented FTWs and CWs can efficiently remove hydrocarbons from the water, their efficiency has never been compared for the remediation of PAH-contaminated water [27,28].…”
