Decoloration of Amaranth by the white-rot fungus Trametes versicolor. Part II. Verification study.

摘要

The involvement of lignin peroxidase (LiP) in the decoloration of the mono-azo substituted napthalenic dye Amaranth was investigated with pure enzymes and whole cultures of Trametes versicolor. The verification study confirmed that LiP has a direct influence on the initial decoloration rate and showed that another enzyme, which does not need hydrogen peroxide to function and is not a laccase, also plays a role during decoloration. These results confirm the results of a previous statistical analysis. Furthermore, the fungal mycelium affects the performance of the decoloration process.
