Various physicochemical and biological techniques can be
employed to remove dyes from wastewaters. They include
the membrane coagulation/flocculation [1], ion exchange [2],
advanced oxidation (chlorination, ozonation) [3], decolourisation
and metabolism of the commercially used Remazol dye by a strain
of P. Chrysosporium [4], and biological treatment (bacterial and
fungal biosorption), biodegradation in aerobic or anaerobic conditions
