Evaluation of Efficient Extraction Methods for Recovery of Photosynthetic Pigments from Microalgae

A. Ilavarasi, D. Pandiaraj, D. MubarakAli, M.H. Mohammed Ilyas and N. Thajuddin

Abstract:
Microalgal species are known to have pigments in their cellular constitute at the maximum and are valuable bioactive products. In the present study focused was on the evaluation of efficient extraction methods for photosynthetic pigments from microalgal species. They are, Chlorella sp., Acrochaete sp., Phormidium chlorinum, Jaaginema pseudogeminatum and Chroococcus sp. There are four different extraction methods were adopted for active recovery and are economically feasible such as direct extraction, mechanical grinding, heating and preheated solvent method. It was found that mechanical grinding method has extract two fold increased amount than the other methods. Additionally, this methods is inexpensive, less laborious and active extraction. It is suggested that this method could be used for the extraction of photosynthetic pigments from microalgae for pharmaceutical to biotechnological purpose.
