  In recent decades, microalgae have acquired attention from pharmaceuticals to biofuels. The growth and total chorophyll content of three economically important microalgae (Chlorella sp. NTAI01, Monoraphidium sp. NTAI02 and Scenedesmus sp. NTAI03) isolated from fresh water body in five selected culture media on different days of incubation was studied for biomass production. Biomass feedstock has reviewed great interest to be used as an alternative and renewable source of energy. All the three organisms showed varied growth pattern and total chlorophyll content in different culture media. However the growth and total chlorophyll content of Chlorella sp. NTAI01 and Monoraphidium sp. NTAI02 was optimum in Half strength Chu 10 medium. In case of Scenedesmus sp. NTAI03 the growth and total chlorophyll content was found to be significant in Bold’s Basal medium. The Acidified Bold’s Basal medium and BG-11 medium fairly supports the growth of all the three microalgae whereas the Modified Hoagland’s medium does not support the microalgal growth. The optimized growth medium will be used for biomass production for biofuel application.

  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.
