https://www.selleckchem.com/products/gossypol.html An electrochemical membrane-aerated biofilm reactor (EMABR) was developed for removing sulfamethoxazole (SMX) and trimethoprim (TMP) from contaminated water. The exertion of electric field greatly enhanced the degradation of SMX and TMP in the EMABR (~60%) compared to membrane-aerated biofilm reactor (MABR, less then 10%), due to the synergistic effects of the electro-oxidation (the generation of reactive oxygen species) and biological degradation. Microbial community analyses demonstrated that the EMABR enriched the genus of Xanthobacter, which was potentially capable of degrading aromatic intermediates. Moreover, the EMABR had a lower relative abundance of antibiotic resistance genes (ARGs) (0.23) compared to the MABR (0.56), suggesting the suppression of ARGs in the EMABR. Further, the SMX and TMP degradation pathways were proposed based on the detection of key intermediate products. This study demonstrated the potential of EMABR as an effective technology for removing antibiotics from micro-polluted surface water and suppressing the development of ARGs.In this study, torrefaction under mechanical pressure of 10-70 MPa at 250 °C was proposed as a pretreatment method and its effect on pyrolysis behaviours of Leucaena (LC) was examined at 900 °C. It was found that the mechanical pressure applied during torrefaction could significantly increase the char yield at 900 °C. The char yield increased from 18.7% for Raw to 26.4% and 27.5% for MP40 and MP70, respectively. The %C of biochar prepared from MP40 (MP40-900) was 86.5%, whereas the %C of biochar prepared from raw (Raw-900) was 82.6%. From TG-MS analyses during the pyrolysis of MP, a large amount of oxygen was removed as H2O and CO2. The analyses of tars produced from MP showed higher fraction of acids and furans compared with tar produced from Raw. Furthermore, the mechanism of the pyrolysis of LC torrefied under mechanical pressure was discussed.The aim of this s
