Textile industries use large amounts of water and a wide variety of synthetic dyes. A small concentration of these dyes released in the environment can be extremely toxic in aquatic ecosystems. Among dye removal processes, adsorption, biosorption and biodegradation are the most advantageous techniques. In order to increase the efficiency of these processes, cell immobilization allows that metabolic processes can take place in adverse conditions. Therefore, this study aims the use of Saccharomyces cerevisiae immobilized in activated sugarcane bagasse to promote Acid Black 48 dye (AB48)...
