Summary: Exposure to MTBE during late puberty compromises the development of Leydig cells in male rats by inhibiting cell proliferation, inducing mitochondrial autophagy and apoptosis, and indirectly stimulating Sertoli cells to secrete anti-Mullerian hormones, resulting in a reduced number of Leydig cells.

Summary: This study investigated the adsorption performance of mesoporous magnesia and commercial adsorbent on MTBE, showing high adsorption capacity. The Langmuir isotherm model and pseudo-second-order kinetics fitted well to predict the adsorption behavior, and the re-use of mesoporous magnesia demonstrated good performance.

Summary: This study proposes and systematically investigates the technology for absorbing MTBE with ionic liquids, from the molecular level to system scale. The research demonstrates that ILs are potential absorbents, and IL-based mixed absorbents may be a better strategy for achieving highly efficient absorption of MTBE, reducing product gas loss and energy consumption.

Summary: In this study, a methyl-modified silica layer (MSL) was supported on porous alpha-Al2O3 ceramic membranes for MTBE/water separation. The MSL, formed by the sol-gel reaction and dip-coating method, combined methyl-modified silica species and pre-synthesized mesoporous silica microspheres to create a hydrophobic mesoporous layer. The MSL-supported alpha-Al2O3 ceramic membranes exhibited high separation factor and total flux.

Summary: This study investigated the effects of MTBE on oxidative stress and DNA damage in earthworms. The results showed that MTBE treatment increased the production of ROS, activated defense enzymes, and caused DNA damage in earthworms. This study contributes to a better understanding of the impact of MTBE on soil invertebrate animals.

Summary: Fatty acids are used as biomarkers to assess prey contribution to consumer diet and define food web structure. Traditional lipid extraction methods involve the use of environmental pollutants. This study found that methyl tert-butyl ether (MTBE) is a reliable alternative for lipid extraction in marine ecological studies.

Summary: In this study, three strains with high adaptability and different degrading characteristics to MTBE were cultured, and kinetic models were established to simulate the biodegradation process of MTBE by the strains at different concentrations. The study found that a mixed consortium of the three strains significantly enhanced the removal efficiency and rate of MTBE, especially at high concentrations. Furthermore, the mixed consortium showed strong adaptability and effectively removed other gasoline components. This research provides support for the use of a mixed consortium to remediate MTBE-contaminated environments.

Summary: Pt/Au NPs@Co3O4 composites with a hollow dodecahedron three-dimensional structure were successfully synthesized, and a CTL sensor based on this composite was established for the accurate and rapid detection of MSBE in MTBE. The experimental results demonstrated that the sensor exhibited strong specificity and sensitivity, and the analytical results were consistent with those obtained using traditional gas chromatography.

Summary: The kinetics of the simultaneous synthesis of ETBE and BTBE over A35 catalyst in the liquid phase was investigated. Various kinetic modeling approaches were compared, and it was found that empirical power-law modeling provided the best fit, while mechanistic modeling explained the reaction mechanisms.

Summary: After 24 weeks of experiment, it was found that exposure to methyl tertiary-butyl ether (MTBE) can significantly reduce serum levels of high-density lipoprotein cholesterol (HDL-C) and significantly increase serum levels of very low-density lipoprotein (VLDL). Through metabolomics analysis, 23 metabolites were identified that may play a key role in systemic energy metabolism. Further pathway analysis showed that MTBE significantly influenced the processes of D-glutamine, D-glutamate metabolism, and three other pathways.

Summary: MTBE, an aliphatic matter, can be successfully removed from contaminated water through advanced oxidation process. This study investigates the effect of arsenic on the photocatalytic removal of MTBE using Fe2O3/MgO catalyst, and finds that arsenic presence remarkably decreases the removal efficiency.

Summary: The addition of water to supercritical tert-butyl methyl ether enhances biodiesel yield, with the optimal conditions being 25 wt% water addition, 300 degrees C temperature, 20 MPa pressure, and 30 min space time resulting in a 77.39 wt% biodiesel yield. The reaction rate is accelerated by water, acting as a catalyst, and the supercritical reaction is found to be endothermic, endergonic, and non-spontaneous based on thermodynamic parameters.

Summary: This study investigated the efficient separation of MTBE from gasoline using ILs and explored the separation mechanism using quantum chemistry and molecular dynamics. The results showed that 1-butyl-3-methylimidazolium nitrate and 1-ethanyl-3-methylimidazole hydrogen sulfate had the highest extraction rate.

Summary: In this study, an MTBE-degrading enzyme, prmABCD, was identified and its role in MTBE metabolism was revealed. Transcriptome analysis showed that the expression of prmABCD was upregulated by MTBE. Functional characterization demonstrated that prmABCD could catalyze the degradation of MTBE, and the loss of genes encoding the oxygenase subunits, coupling protein, or reductase disrupted MTBE degradation. The catalytic capacity of PRM was influenced by specific amino acid residues in the active site and substrate tunnel.
