BIOCHEMICAL AND PIGMENT ANALYSIS ON PHYCOREMEDIATED MICROALGAL BIOMASS

Phycoremediation is a term of treating microalgae with waste water to reduce thetoxic elements in it. Textile dye industrial effluents contain highly concentrated CO2 andNitrogen in it, which causes severe harmful effects to human and to the environment. Thereduction of Physiochemical parameters were seen from before and after treated effluents.Biochemical analysis from the microalgae biomass reveals that Scenedesmus obliquus, Chlorellavulgaris and its consortium have shown high amount of Protein and Lipid in ascending order.Microalgae pigments such as chlorophyll a, b and â-carotene were determined and â-carotenefound high amount than chlorophyll from all the treated biomass as expected but high thannormal grown media. Scenedesmus obliquus is found to be the highest producer of â-carotene.Positive and negative correlation were analysed between removal of nitrogen from the effluentand increase in protein content and removal of COD from the effluent and high lipid content(Positive) and Increase in Lipid content leads to decrease in â-carotene levels (Negative).
