Contaminants of Emerging Concern (CECs) are human-made chemicals that remain unregulated. The continuous detection CECs in aquatic ecosystems, due to their incomplete removal, emphasizes the importance understanding fate and impact on environment human health. detrimental effects marine eukaryotes well documented multiple studies. However, bacteria biodegradation by these organisms not understood. In this study, two bacteria, Priestia sp 35 ODPABA G14 Rhodococcus 23 AHTN G14, previously isolated from submarine sediments, were used. These strains tested for resistance as capacity degrade different classes hydrophobic hydrophilic CECs, including synthetic musks, UV filters, pesticides pharmaceuticals. Both showed high all even up 500 mg L−1. Only Ketoprofen was toxic bacterial cells, particularly sp. starting at concentration low 4 Furthermore, exhibited potential, especially compounds. Although may apply pollutants, data presented study suggest a positive correlation between potentials.

The unexpected effect of the compound microbial agent NP-M2 on microbial community dynamics in a nonylphenol-contaminated soil: the self-stability of soil ecosystem

PeerJ, Journal Year: 2024, Volume and Issue: 12, P. e17424 - e17424

Background Nonylphenol (NP) is widely recognized as a crucial environmental endocrine-disrupting chemical and persistent toxic substance. The remediation of NP-contaminated sites primarily relies on biological degradation. Compound microbial products, opposed to pure strains, possess greater variety metabolic pathways can thrive in wider range conditions. This characteristic believed facilitate the synergistic degradation pollutants. Limited research has been conducted thoroughly examine potential compatibility compound agents with indigenous microflora, their ability function effectively practical environments, capacity enhance dissipation NP, improve soil physicochemical characteristics. Methods In order efficiently eliminate NP contaminated an eco-friendly manner, simulation study was investigate impact bioaugmentation using functional agent NP-M2 at varying concentrations (50 200 mg/L) dynamics community. treatments were set follows: sterilized 50 mg/kg (CK50) or (CK200); non-sterilized (TU50) (TU200); (J50) (J200). Full-length 16S rRNA analysis performed PacBio Sequel II platform. Results Both microbes (TU50 TU200 treatments) application (J50 J200 exhibited rapid removal, removal rates ranging from 93% 99%. further accelerated rate for subtle lag period.

Transfer of Bisphenol A and Trace Metals from Plastic Packaging to Mineral Water in Ouagadougou, Burkina Faso

International Journal of Environmental Research and Public Health, Journal Year: 2023, Volume and Issue: 20(20), P. 6908 - 6908

Published: Oct. 11, 2023

The consumption of packaged water is growing rapidly in both urban and rural centres Burkina Faso. Bisphenol A (BPA) trace metals are among the compounds used manufacture plastic packaging, their presence can pose a health risk to consumers due alleged toxicity. Therefore, this study explores transfer these from packaging mineral Sudano-Sahelian climatic conditions. Ten samples sachet commercialised Ouagadougou were studied. An absence BPA borehole produce has been shown. into increases with storage temperature. that appears degrades over time. concentrations ranged 0 0.38 mg/L after two weeks storage, 0.8 four 0.35 8 storage.

Background: Bisphenol A (BPA), is an organic component, functions as endocrine disruptor (EDC). It ubiquitously exists in both, the environment and food sources, leading to continuous unintentional exposure among populations of human animal. Aim Study: Investigate biodegradation activity BPA by bacteria isolated from polluted soil with plastic wastes. Materials Methods: 50 samples were taken wastes different sites Kerbala province; minimal salt media (MSM) used identify capability isolates bioremediate 200 mg/L, a final concentration using HPLC analysis. Results: bacterial could degrade ranges started 18.7% 99.9%. recent study found that, Serratia plymuthica, Pantoea spp, Shingomonas paucimobilis, Pseudomonas aeruginosa Bacillus spp. more efficient than Acinetobacter haemolyticus, lwoffii, Escherichia coli Proteus Conclusion: Many types convert toxic compound another metabolites according we employee these eliminate materials safely soils water efficiently chemicals that might be environment, being animals.
