Mart ez1Abstract Background: Regardless of claims as essential enzymes in enzymatic delignification, incredibly scarce information and facts on the reaction rates amongst the ligninolytic versatile peroxidase (VP) and lignin peroxidase (LiP) plus the lignin polymer is offered, resulting from methodological difficulties related to lignin heterogeneity and low solubility. Results: Two watersoluble sulfonated lignins (from Picea abies and Eucalyptus grandis) had been chemically character ized and utilised to estimate single electrontransfer prices towards the H2O2activated Pleurotus eryngii VP (native enzyme and mutated variant) transient states (compounds I and II bearing two and oneelectron deficiencies, respectively). When the ratelimiting reduction of compound II was quantified by stoppedflow fast spectrophotometry, from fourfold (softwood lignin) to over 100fold (hardwood lignin) lower electrontransfe.
