摘要：

Cyanobacteria are widely distributed in the environment and may be an effective and economic alternative for removing dyes from textile industry effluents. The present work investigated the potential of six cyanobacterial strains in decolorizing eleven types of textile dyes. The maximum absorbance of each dye was verified using a spectrophotometer. Mass spectrometry was used to verify the removal and possible degradation of dyes by the cyanobacteria. The results showed that all of the evaluated cyanobacteria were able to remove indigo, palanil yellow, indanthrene yellow, indanthrene blue, dispersol blue, indanthrene red and dispersol red by more than 50%. The Brazilian isolate Phormidium sp. CENA135 was able to decolorize and completely remove indigo blue BANN 30. This study confirmed the capacity of cyanobacteria to decolorize and possibly to structurally degrade different textile dyes, suggesting the possibility of their application in bioremediation studies.
