The aim of this study was to characterize the activity of oxidoreductases during biotransformation of 0.01% anthraquinone dyes: Alizarin Blue Black B (ABBB) and Acid Blue 129 (AB129), Carminic Acid (CA), Remazol Brilliant Blue R (RBBR), Acid Green 25 (AG25) and Poly R-478 by immobilized strain of Bjerkandera adusta CCBAS 930. Phenolic compounds, phytotoxicity (Lepidium sativum L.), biotoxicity were evaluated to determine the toxicity of anthraquinone dyes before and after the treatment with immobilized B. adusta CCBAS 930. More than 60% of CA and AB129 were removed by immobilized B. adusta CCBAS after 7 days. No secondary products toxic to plants and bacteria were formed during immobilized cultures of B. adusta CCBAS 930.
Key words: white-rot fungi / versatile peroxidase / anthraquinone dyes / immobilization
