Elucidating the role of electric field application in promoting humification and identifying enhancement strategies remains a key challenge. This study investigated the role of conductive and redox pathways in enhancing the humification efficiency of EC systems through the incorporation of conductive graphite and sodium lignosulfonate. Compared with EC, the conductive graphite treatment (EGPC) and sodium lignosulfonate treatment (ESLC) increased current intensity by 2.5- and 1.8-fold, respectively. Additionally, humic acid (HA) content increased by 62.34 % in EGPC and 60.86 % in ESLC. EGPC treatment increased the abundance of Bacillus and enhanced synergistic interactions among core bacteria. Conversely, ESLC treatment significantly altered β-diversity and increased the abundance of Flavobacterium during composting. Correlation analysis and partial least squares path modeling indicated that EGPC treatment promoted direct electron transfer and bacterial interactions, thereby enhancing organic matter humification. ESLC treatment improved bacterial community diversity and facilitated the conversion of furanic acid into HA. These findings provide a theoretical basis for optimizing EC and highlight its potential for large-scale application.","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":" ","pages":"133454"},"PeriodicalIF":9.0,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermophilic BMP outperformed mesophilic BMP, yielding 279-309  mL-CH4/g-CODfed. In 340-day continuous experiment, thermophilic AD of the pretreated PHB wastewater in CSTR was confirmed to be feasible at hydraulic retention time (HRT) of 24-30d, with 91-94 % COD removal and 276-290 mL-CH4/g-CODfed. At 20d HRT, crotonate accumulation caused severe methanogenic inhibition. Distinct bacterial communities and co-dominance of Methanosarcina and Methanothermobacter were underlying PHB and intermediate degradation and methanogenesis.

The dual-enzyme reactor was constructed through affinity recognition between artificial antibodies and antigens, a modular strategy that allowed rational regulation of enzyme ratios in the co-immobilized system to match cascade reaction requirements, thereby promoting optimal yield. This GOx-LIP dual-enzyme reactor achieved alkene epoxidation with epoxide yields exceeding 70% under optimized conditions.

For hydrochars and hydropyrochars, graphitization degree, defects, and graphitic/pyridinic/pyrrolic N increased, whereas the stacking degree and number of acidic O-containing groups decreased as the HTC temperature and time increased. The characteristics of the hydrochars significantly affected those of the hydropyrochars, whereas those of the pyrochar were clearly different. In the presence of peroxydisulfate (PDS), acetaminophen (ACT) removal was negligible for hydrochars + PDS, poor for pyrochar + PDS, and excellent for hydropyrochars + PDS. The best ACT removal was >99 % in 20 min with a 20 mg/L hydropyrochar from a hydrochar prepared via HTC at 250 ℃ for 3 h (HY250/03-PY) (PDS 0.05 mM, ACT 5 mg/L). For the hydropyrochars, possible reactive sites, such as the graphitic structure, CO, and pyridinic/graphitic-N, correlated well with the ACT removal rate. Despite the large differences in the performance and characteristics, the dominant reactive species (1O2) and ACT degradation pathways were similar in HY250/03-PY + PDS and pyrochar + PDS. However, HY250/03-PY was significantly superior to pyrochar in 1O2 generation and PDS adsorption. HY250/03-PY + PDS showed significant inhibition by coexisting ions and natural organic matter; however, most of these effects were overcome by simply increasing HY250/03-PY. These results strongly suggest that hydropyrochars with excellent reactivity and field application potential can be prepared by combining HTC control and pyrolysis.","PeriodicalId":258,"journal":{"name":"Bioresource Technology","volume":" ","pages":"133442"},"PeriodicalIF":9.0,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145249193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pretreatment methods such as alkaline or mechanical disruption can enhance solubilization; however, the resulting hydrolysate often contains recalcitrant compounds that inhibit further degradation. In this study, a combination of alkali along with ultrasonication was applied to enhance the solubilization of WAS, followed by CH4 production under AD. Pretreated results showed alkaline (pH = 12) + ultrasonication (30 min) showed 300 % higher solubilization compared to ultrasonication (60 min) alone. Batch experiments (with and without Fe3O4) were conducted, and the results showed that pretreated hydrolysate supplemented Fe3O4 showed higher CH4 yield than their control counterparts (up to 85 %). To validate the batch results of pretreated hydrolysate, a continuous operation was conducted without (Control) and with an electric voltage reactor (EVR) at different organic loading rates (OLR) up to 4 g chemical oxygen demand (COD)/L/d. The results showed that EVR enhanced the CH4 production by 28 % and COD removal by 19 % at 4 g COD/L/d compared to the control. Microbial community analysis highlighted the dominance of Syntrophomonas zehnderi (a fatty acid oxidizer) in EVR, which increased by 27 %, suggesting stronger syntrophic partnerships with methanogens. Genetic profiling further supported these findings, showing a 25 % upregulation in Adenosine triphosphatease related genes and a striking 69 % increase in pili-associated genes, both critical for direct interspecies electron transfer.

The results demonstrated that intermittent magnetic field (IMF) exposure maintained consistently high metabolic activity and nitrogen assimilation capacity in HAA bacteria by improving the utilisation efficiency of electron donors and energy. A 3 h-on/9h-off duty cycle (25 %) achieved the optimal balance between positive stimulation and stress mitigation, leading to a 27.6 % improvement in ammonia removal efficiency.
