The stability and efficacy of the microalgae in long-term repetitive operations was also examined. The results obtained from the experiments revealed that the ability of the select algal species in removing colouring agents from the medium and metals. The effect for physico-chemical parameters on decolorization was examined. The findings provide evidence for the suitability of certain microalgae as indicators of effluent status and determine its composition. https://www.biotech-asia.org/vol6no1/biological-decolorization-and-removal-of-metal-from-dye-industry-effluent-by-microalgae/ Biological decolorization; dye industry effluent; microalgae
