| 摘要 |
A new enzyme-based process for oxidation and/or bleaching is described, comprising of oxidoreductases such as laccases and/or peroxidases-seperately or in combination-in the presence of their respective co-substrates like O<SUB>2</SUB>, air, H<SUB>2</SUB>O<SUB>2</SUB>, organic peroxides, peracids etc. and comprising of enhancer compounds from the class of oxocarbons, from the class of urazoles and hydrazides, from the class of hydantoins and the class of nitril (Cyan)-compounds, and comprising additionally of carbonyl compounds such as ketones, aldehyds, whereby the combination of enzyme, co-substrate, enhancer compound and carbonyl compound generate active oxygen species like dioxiranes, dioxetanes, peroxy-compounds etc. or form other reactive compounds or transition states like radicals (kation radicals, anion radicals) or reactive (red/ox-active) neutral compounds as oxidizing and/or bleaching agents.
