| Releasing of textile dye effluents into general water bodies is a major environmental and health problem. Color removal, in particular, has recently become of major scientific interest, as indicated by the multitude of related research reports. During the past two decades, several physico-chemical decolorization techniques have been reported, few, however, have been accepted by the textile industries. Their lack of implementation has been largely due to high cost, low efficiency and inapplicability to a wide variety of dyes. The ability of microorganisms to carry out dye decolorization has received much attention. Green algae and blue green algae are considered as an important source for decolorizing dye and textile effluent. The dye Congo red and textile dye effluent is chosen for this investigation and the green algae Haematococcus sp., Chlorella sp., Chlorella vulgaris, Scenedesmus obliquuss, S. officinalis, and S. quadricauda and blue green algae Arthospira maxima was used for the decolorization process. Chlorophyll, protein content of this organism was tested before and after the treatment. Haematococcus sp shown the maximum degradation among all the seven microalgae was found at 10ppm which was 98%, which decolorize the textile effluent efficiently in short period of time. | ||
