Negative public sentiment built up around bisphenol A (BPA) follows growing awareness of the frequency this chemical compound in environment. The increase air, water, and soil contamination by BPA has also generated need to replace it with less toxic analogs, such as Bisphenol F (BPF) S (BPS). However, due structural similarity BPF BPS BPA, questions arise about safety their usage. toxicity BPF, towards humans animals been fairly well understood. biodegradability potential microorganisms each these bisphenols is widely recognized. scale inhibitory pressure on microbiomes enzyme activity not estimated. These parameters are extremely important determining health, which turn influences plant growth development. Therefore, manuscript, knowledge expanded systematized regarding differences between its two analogs.

Study on Genomics of the Bisphenol A-Degrading Bacterium Pseudomonas sp. P1

Water, Journal Year: 2023, Volume and Issue: 15(4), P. 830 - 830

Published: Feb. 20, 2023

As a widespread pollutant, bisphenol A (BPA) has created serious threat to ecosystem and human health. Therefore, expanding the available microbial resources used screen highly efficient BPA-degrading bacteria with BPA as sole carbon source is very important for removal of this pollutant from environment. In study, degradation rate Pseudomonas sp. P1 30 mg/L was 96.89% within 120 h. Whole genome sequencing showed that strain composed single circular chromosome full length 6.17 Mb, which contained 5636 predicted coding genes. Comparative genomic analysis 210 functional genes related degradation. It confirmed ferredoxin (bisdA), P450 (bisdB), CotA Lac in were expressed under induction BPA.

The Threat of Bis(2-Ethylhexyl) Phthalate in Coastal and Marine Environments: Ecotoxicological Assays Using Tropical Species from Different Trophic Levels

International Journal of Environmental Research and Public Health, Journal Year: 2025, Volume and Issue: 22(3), P. 402 - 402

Published: March 10, 2025

Plastic and plasticizer pollution has been a concern worldwide over the past decade. Bis(2-ethylhexyl) phthalate (DEHP) is most produced detected in coastal marine ecosystems. This study aimed to assess toxicity of acute exposure (24, 48, 72, 96 h) DEHP concentrations (0.045–6.00 mg·L−1) on estuarine tropical species from distinct trophic levels. The lethality sublethal responses were assessed two microorganisms three invertebrates, independently. microorganisms—the microalga Tetraselmis sp. microbial consortium MP001—showed high tolerance density-rising tendency during DEHP. Among mortality brine shrimp Artemia amphipod Apohyale media rose with increasing concentrations. However, A. was more sensitive across time since its reached 100% almost all 72 h. dark false mussel Mytilopsis leucophaeata tolerant invertebrate: no significant (≤20%) observed exclusively h at intermediate–high M. presented that seem be good endpoints for ecotoxicological assays. These results reinforce evidence contamination risks ecosystems, as well suggest candidate biodegradation.

Effects of different concentrations of chlormequat chloride on bacterial community composition and diversity in peanut soil

BMC Microbiology, Journal Year: 2025, Volume and Issue: 25(1)

Published: March 11, 2025

The application of pesticides may have significant impacts on soil environment and communities. In order to understand the deep relationship between chlormequat chloride (CC) bacterial community in peanut soil, high-resolution characterization was performed using samples (12 points; 0-20 cm rhizosphere soil) from untreated sprayed with different concentrations CC. Experimental data showed that increase concentration, operational taxonomic units (OTUs) richness a decreasing tendency. OTUs at low concentration (D, 50% CC diluted 5000 times, 45 g ai/ha), medium (M, 300 75 high (G, 1000 225 ai/ha) were 5583, 5430, 3910, respectively. Low increased composition relative abundance contrast, significantly reduced diversity. As increases, Proteobacteria decreases, while Firmicutes Bacteroidetes increases. number Acidobacterium groups D M, it decreased group G.

Mangrove consortium resistant to the emerging contaminant DEHP: Composition, diversity, and ecological function of bacteria

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(4), P. e0320579 - e0320579

Published: April 24, 2025

The continuous use of Di(2-ethylhexyl) phthalate (DEHP) in plastic products turns it into a ubiquitous contaminant the environment. However, DEHP can cause harm to human beings, wildlife, and ecosystems due its estrogenicity toxicity. Thus, finding an efficient approach removing this from environment is crucial. present study aimed prospect characterize bacterial consortium (MP001) isolated neotropical mangrove for bioremediation. A laboratory experiment was performed with environmentally relevant concentrations (0.05, 0.09, 0.19, 0.38, 0.75, 1.50, 3.00, 6.00 mg L -1 ) determine resistance high-throughput sequencing accomplished assess composition, diversity, potential ecological function MP001. MP001 presented significant biomass increase throughout short-term incubations increasing (GLMs, p< 0.001). constituted by Paraclostridium sp. (78.99%) Bacillus (10.73%). After 48 h consortia exposure DEHP, population changed (50.00%), Staphylococcus (12.72%) , epidermidis (10.40%) sp . (17.63%). In negative control, bacteria community composed (54.02%), Pseudomonas stutzeri (19.44%), (11.97%). alpha diversity not (Kruskall-Wallis; p > 0.05), no difference found between treatment control. Furthermore, higher application bioremediation purposes fermentation. results highlight be used DEHP-contaminated aquatic environments.
