However, the inherent structure of Kraft lignin, as well as that resulting from laccase modification, still presents challenges for fundamental comprehension and successful lignin valorization. In this study, bacterial and fungal laccases were employed to modify eucalypt Kraft lignin. To evaluate the type and range of the chemical and structural changes of laccase-treated lignins, different NMR techniques, including solution 1H and 2D NMR (heteronuclear single quantum correlation (HSQC)), and solid-state 13C NMR, were applied. Size exclusion chromatography and infrared spectroscopy were also used. Interestingly, HSQC analysis showed substantial changes in the oxygenated aliphatic region of lignins, showing an almost complete absence of signals corresponding to side-chains due to laccase depolymerization. Simultaneously, a significant loss of aromatic signals was observed by HSQC and 1H NMR, which was attributed to a deprotonation of the lignin benzenic rings due to polymerization/condensation by laccase reactions. Then, condensed structures, such as α-5', 5-5', and 4-O-5', were detected by HSQC and 13C NMR, supporting the increment in molecular weight, as well as the phenolic content reduction determined in lignins.This research was funded by Comunidad de Madrid via Project SUSTEC-CM S2018/EMT-4348; MCINN/AEI/10.13039/501100011033 and by “ERDF A way of making Europe” via Project RTI2018-096080-B-C22; and MCINN via Project TED2021-132122B-C21.Peer reviewedMultidisciplinary Digital Publishing InstituteComunidad de MadridAgencia Estatal de Investigación (España)Ministerio de Ciencia e Innovación (España)Ibarra Trejo, David [0000-0003-3001-7308]García-Fuentevilla, Luisa [0000-0001-8255-0097]Domínguez, Gabriela [0000-0001-7358-0913]Martín-Sampedro, Raquel [0000-0003-2083-3723]Arias, María Enriqueta [0000-0002-6804-1779]Santos, José I.
