It can undermine downstream anaerobic wastewater treatment processes, such as upflow anaerobic sludge blanket (UASB) treatment, especially under short hydraulic retention time (HRT). The inhibition effects result from its high chemical oxygen demand (COD) and propionate\u2010skewed volatile fatty acid (VFA) profile. Given its small volume and the availability of low\u2010grade heat on\u2010site, a mild pretreatment compatible with existing infrastructure is desirable. In this study, low\u2010temperature thermal pretreatment (LTTP; 50\u00b0C\u201390\u00b0C, atmospheric operation) was evaluated as a low\u2010grade\u2010heat\u2010compatible conditioning step for improving the short\u2010term anaerobic response of tobacco\u2010stem extraction wastewater. The 48\u2010h short\u2010term methane production (STMP) peaked at 111.8\u2009\u00b1\u20096.1\u2009mL CH\n                    <jats:sub>4<\/jats:sub>\n                    \u00b7g COD\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 90\u00b0C for 90\u2009min, corresponding to a 2.1\u2010fold increase relative to the untreated wastewater. LTTP also shifted the VFA profile from propionate\u2010dominant to acetate\u2010dominant: The acetate\u2010to\u2010propionate ratio increased from 1.0 at 50\u00b0C for 30\u2009min to 11.5 at 90\u00b0C for 90\u2009min. In parallel, COD, pH, and oxidation\u2013reduction potential (ORP) changed only modestly, and no statistically detectable changes in bulk cellulose, hemicellulose, or lignin fractions were observed. The parallel factor analysis (PARAFAC) revealed broad increases in protein\u2010like and humic\u2010\/fulvic\u2010like fluorescent DOM components. These results indicate that LTTP mainly induced liquid\u2010phase mobilization and VFA redistribution rather than measurable bulk lignocellulosic disintegration. Overall, LTTP may provide a gentle, low\u2010grade\u2010heat\u2010compatible side\u2010stream conditioning option for improving the short\u2010term anaerobic treatability of tobacco\u2010stem extraction wastewater.\n                  <\/jats:p>","DOI":"10.1002\/wer.70517","type":"journal-article","created":{"date-parts":[[2026,7,30]],"date-time":"2026-07-30T07:37:15Z","timestamp":1785397035000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Low\u2010Temperature Thermal Pretreatment of Tobacco\u2010Stem Extraction Wastewater: Volatile Fatty Acid Redistribution and Short\u2010Term Methane Production Response"],"prefix":"10.1002","volume":"98","author":[{"given":"Lili","family":"Sun","sequence":"first","affiliation":[{"name":"Anhui Provincial Key Laboratory of Aerosol Analysis, Modulation and Biological Effect  Hefei China"},{"name":"Technology Center China Tobacco Anhui Industrial Co.
