At present it is very important to screen the indigenous hyper-lipid producing microalgae for Biofuel application and should cultivate native microalgal strains that adapt to their local environment conditions. As part of pioneering efforts to assess the potential of native microalgae as biofuel feedstock in Tamil Nadu India, six microalgae (corresponding to the Phylum Chlorophyta) from a total of 25 isolated cultures were selected based on their morphology and ease of cultivation under our laboratory condition. Six strains were identified as Scenedesmus armatus FW005, S. deserticola FW006, Chlorella vulgaris PRR04, S. obliquus PRR02, C. vulgaris SE002 and S.dimorphus PRR05 based on 18s and LSU (D1-D2) rDNA sequence analysis. Among the six species, C. vulgaris PRR04 showed a higher biomass productivity 1.72 ± 0.06 g d wt L-1. The fatty acid compositions of the six species were studied and the major fatty acids are lauric acid, palmitic acid and oleic acid comprising of 5-35%, 16-54% and 3-34% of the total fatty acids. Oleic acid, occupied up to 34% of the total fatty acids in C. vulgaris SE002 which is an ideal component of biodiesel hence we suggest they might represent valuable resources for future research towards the regional development of the technology for microalgae-based biofuels. | | Keywords : | | |
