Oxidation of non‐phenolic substrates: An expanded role for laccase in lignin biodegradation
Abstract
In the presence of substrates such as Remazol Blue and 2,2'‐azinobis(3‐ethylbenzthiazoline‐6‐sulphonate) (ABTS), laccases Coriolus (Trametes) versicolor can also oxidize non‐phenolic lignin model compounds. Veratryl alcohol (I) and 1‐(3,4‐dimethoxyphenyl)‐2‐(2‐methoxyphenoxy)‐propane‐1, 3‐diol (III) were oxidized by laccase and mediator to give the α‐carbonyl derivatives. The β‐1 lignin model dimer, 1‐(3,4‐dimethoxyphenyl)‐2‐phenoxy‐ethane‐1, 2‐diol(II) was cleaved by laccase in the presence of ABTS to give veratraldehyde and benzaldehyde. On the basis of these observations, we propose that laccase is capable of oxidizing both phenolic and non‐phenolic moieties of lignin but that the latter is dependent on the co‐presence of primary laccase substrates.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
