Zusammenfassung:	The use of white-rot fungi, especially Trametes versicolor and isolate IZU-154, to delignify and brighten kraft pulps is reviewed. The fungal treatments are effective but slow; the responsible enzymes are being studied with a view to accelerating the process. Manganese peroxidase, or laccase with a co-substrate, can demethylate and partially solubilize the lignin in pulps, mimicking the early steps of the fungal delignification.
