文摘内容 Several wood rotting fungi decolourized Remazol brilliant blue R (RBBR) and carminic acid (CA). Parallel activity of laccase in these fungi was studied. The addition of acetovanillone (AV) or acetosyringone (AS) intensified these processes: decolourization was more extensive than in the experiment omitting these compounds. At the presence of AS the decourization was more extensive than AV. However the level of decolorizing was relatively low in comparison to laccase activity on syringaldazine. The highly purified constitutive form of Cerrena unicolor and inducible form of Trametes versicolor laccases also destained both dyes. Anyway the addition of AV and AS improved the efficiency of dyes decolourization by wood rotting fungi and fungal laccase. Nitrogen starvation induced the laccase and decoloration activity in both organisms, irrespective of nitrogen availability. This fact indicates laccase not solely responsible for discoloration, and probably discoloration of dyes involves more than one mechanism。
