In this study, choline chloride\u2013monoethanolamine (ChCl-MEA)-based solvent systems containing H2O2, NaHCO3, Na2S, or ethylene glycol were prepared and applied for the pretreatment of Dendrocalamus brandisii. Among the tested systems, ChCl-MEA-Na2S showed the best overall pretreatment performance, achieving 92.8 \u00b1 2.3% delignification and 86.1 \u00b1 1.7% cellulose retention. It also effectively disrupted lignin\u2013carbohydrate associations, reduced lignin shielding and generated a more accessible cellulose-rich substrate for bioconversion. In the following separation enzymatic hydrolysis and fermentation, 92.2 \u00b1 2.2% cellulose in substrate was converted to glucose, and 17.49 \u00b1 0.7 g\/L ethanol was obtained via the fermentation of enzymatic hydrolysate. Taking the bioconversion of substrate into consideration, the ChCl-MEA-H2O2 and ChCl-MEA-Na2S were recovered for full component utilization. Especially, the carbon dots produced from the degradation compounds in ChCl-MEA-H2O2 DESs had favorable antioxidation and antibacterial performance due to the oxygen-containing group caused by oxidation of H2O2.<\/jats:p>","DOI":"10.3390\/molecules31111832","type":"journal-article","created":{"date-parts":[[2026,5,26]],"date-time":"2026-05-26T13:28:21Z","timestamp":1779802101000},"page":"1832","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Third-Component-Regulated Choline Chloride\u2013Monoethanolamine-Based Solvent Systems for Enhanced Valorization of Bamboo Toward Concurrent Bioethanol and Carbon Dot Production"],"prefix":"10.3390","volume":"31","author":[{"given":"Sicheng","family":"Jin","sequence":"first","affiliation":[{"name":"College of Material and Chemical Engineering, Southwest Forestry University, Kunming 650224, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-2441-3319","authenticated-orcid":false,"given":"Yongan","family":"Meng","sequence":"additional","affiliation":[{"name":"College of Material and Chemical Engineering, Southwest Forestry University, Kunming 650224, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongtian","family":"Miao","sequence":"additional","affiliation":[{"name":"College of Material and Chemical Engineering, Southwest Forestry University, Kunming 650224, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chun","family":"Shi","sequence":"additional","affiliation":[{"name":"College of Material and Chemical Engineering, Southwest Forestry University, Kunming 650224, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Material and Chemical Engineering, Southwest Forestry University, Kunming 650224, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengjun","family":"Shi","sequence":"additional","affiliation":[{"name":"College of Material and Chemical Engineering, Southwest Forestry University, Kunming 650224, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haiyan","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Material and Chemical Engineering, Southwest Forestry University, Kunming 650224, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1232","DOI":"10.1021\/acs.chemrev.0c00385","article-title":"Deep Eutectic Solvents: A Review of Fundamentals and Applications","volume":"121","author":"Hansen","year":"2021","journal-title":"Chem.
