[en] Water solutions of different dyes used in textile industry (Reactive Black 5, Acid Orange 7 and Disperse Yellow 5) were treated under laboratory conditions by means of different microorganisms or their metabolites. The following organisms were used in this study: Bacillus megatherium, B.subtilus, B.circulans, activated sludge from industrial w. w. teratment plant and a mixed enriched culture of flocculating bacteria. It was find out that the microbial effect towards the dyes was quite specific and the extent of colour removal varied in broad range. Very good results were achieved also by means of permeable reactive barriers inhabitated by flocculating bacteria and other independent microorganisms and operating under continuous flow conditions. The colour removal in these case varied in the range of about 80 - 90 % and was similar to that achieved by the well known chemical reagents used in the textile industry.
