BIOCHEMICAL AND PIGMENT ANALYSIS ON PHYCOREMEDIATED MICROALGAL BIOMASS

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