Dichloromethane emerges as the toxic malodor that causes carcinogenicity, mutagenicity and teratogenicity. The aim of the present study was to find out the potency of hybrid materials for the removal of dichloromethane using raw rice husk, coconut shell, metal organic framework and <i>Pseudomonas aeruginosa</i>. The identification of bacteria was done by biochemical methods and 16SrRNA test. The characterization of adsorbents was done using sophisticated fourier transform infrared, field emission scanning electron microscopy and x-ray diffraction technique. The particle size of adsorbents was calculated using the Scherrer equation. The analysis of the final concentration of dichloromethane in hybrid materials was done by gas chromatography-flame ionization detector. The removal percentage obtained using Pse + RRH, Pse + CSAC, Pse + MOF (UiO-66(Zr), Pse + RRH + CSAC, Pse + RRH + CSAC + MOF (UiO-66)(Zr) was 96.87%, 99.80%, 97.63%, 97.35%, 98.08%, respectively with 50 mg/L of dichloromethane concentration.

Biotransformation is a high-potential and low-cost way to remove PMPs, where ammonia-oxidizing microorganisms (AOM) are essential for eliminating pharmaceutical micropollutants. On the other hand, AOM are associated with nitrous oxide (N₂O) emission generation in nitrifying. In this sense, micropollutants can inhibit the activity of AOB, reducing the ammonia oxidation rate and increasing N₂O emissions. To mitigate these challenges, systems that allow satisfactory performance of the metabolism of AOB and NOB, such as the Sequencing Batch Reactor (SBR) and Sequencing Batch Biofilm Reactor (SBBR), are essential. However, no systematic review of the advances or gaps in this field has been published, mainly focused on SBR or SBBR. Thus, this work reviews recent advances regarding PMP biotransformation and N₂O production by AOM, emphasizing SBR and SBBR systems. Besides, we compare the removal performances of various micropollutants in biological processes. The biotransformation of emerging pollutants was also presented to explore the metabolic pathways of N₂O production and the critical factors that influence N₂O emissions in biological processes. Controlling DO levels, intermittent aeration, and maintaining low ammonium concentrations can help mitigate N₂O emissions. The simultaneous removal of PMPs and N₂O emissions was also analyzed; however, there is still limited research regarding the effect of PMPs on N₂O emission production in the nitrification process using SBR or SBBR. However, SBBRs may provide a more stable platform for both PMP removal and minimized emissions, mainly when biofilm characteristics and intermittent aeration are well managed. Thus, this review gives a complete vision of the advances of SBR and SBBR to remove PMPs and minimize the N₂O, as well as the future directions that research needs to address to improve the PMPs biotransformation and N₂O minimization.</p></div>","PeriodicalId":486,"journal":{"name":"Biodegradation","volume":"36 3","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, urease-producing bacteria have gained attention for their ability to remove heavy metals through microbial-induced carbonate precipitation (MICP). In this study, eight urease-producing bacteria were exposed to individual solutions of zinc (Zn²⁺), cadmium (Cd²⁺), and nickel (Ni²⁺) at concentrations ranging from 0 to 6 mM to assess their resistance. Three strains—<i>Bacillus subtilis</i> HMZC1 (B2), <i>Bacillus sp.</i> HMZCSW (B6), and <i>Comamonas sp.</i> HMZC (B11)—survived at 4 mM and 6 mM, while most others could not tolerate 4 mM.

This study presents the first investigation into the genetic responses of anammox bacteria to elevated N₂H₄ concentrations, offering critical insights into their potential for sustainable environmental applications. In this scope, anammox cultures were exposed to high levels of N₂H₄ (up to 3 g/L) over a short-term period to evaluate their nitrogen treatment capacity and transcriptional responses. The results indicated that anammox activity continued at N₂H₄ concentrations of 1.88 g/L or less. However, acute N₂H₄ exposure significantly downregulated key genes, such as acetyl-CoA synthase beta and delta subunits, hydrazine synthase, hydrazine dehydrogenase, and hydroxylamine oxidoreductase, except for AAA family ATPase. Overall, high exogenous N₂H₄ concentrations severely constrained the metabolism and survival of anammox bacteria at a molecular level. Understanding the genetic responses of anammox bacteria to elevated N₂H₄ concentrations is crucial for optimizing their application in further anammox-based technologies.

The purpose of the experiment was to study the effect of lead (Pb), cadmium (Cd), and arsenic (As) on the growth, photosynthetic pigments content, enzymatic and low molecular weight antioxidants, and the uptake of metals in the wheat seedlings. We carried out a pot experiment in which HMs were introduced into the soil Pb (1300 mg kg^–1), Cd (20 mg kg^–1), As (100 mg kg^–1) separately and all together in one combination and an uncontaminated control. The doses of HMs corresponded to the registered high pollution level in impact zone (10 approximate permissible concentrations). The results showed that HMs contamination of the soil affected the growth, photosynthetic pigments and antioxidant enzymes activities in wheat. The polyelement contamination significantly reduced root growth. The polyelement contamination led to an intensification of lipid peroxidation processes, which was reflected in an increase in malondialdehyde content in leaves and roots by 39% and 127% compared with the control. The cumulative exposure affected antioxidants in wheat, leading to deregulation of defense mechanisms, characterized by an increase in reduced glutathione content in leaves and roots by 23% and 69%, an increase in proline and ascorbic acid content in leaves by 174% and 20%, and a decrease in roots by 80% and 43%, respectively.
