Molecular Identification and Comparative Evaluation of Tropical Marine Microalgae for Biodiesel Production

Molecular Identification and Comparative Evaluation of Tropical Marine Microalgae for Biodiesel... Marine microalgae have emerged as important feedstock for liquid biofuel production. The identification of lipid-rich native microalgal species with high growth rate and optimal fatty acid profile and biodiesel properties is the most challenging step in microalgae-based biodiesel production. In this study, attempts have been made to bio-prospect the biodiesel production potential of marine and brackish water microalgal isolates from the west coast of India. A total of 14 microalgal species were isolated, identified using specific molecular markers and based on the lipid content; seven species with total lipid content above 20% of dry cell weight were selected for assessing biodiesel production potential in terms of lipid and biomass productivities, nile red fluorescence, fatty acid profile and biodiesel properties. On comparative analysis, the diatoms were proven to be promising based on the overall desirable properties for biodiesel production. The most potential strain Navicula phyllepta MACC8 with a total lipid content of 26.54 % of dry weight of biomass, the highest growth rate (0.58 day−1) and lipid and biomass productivities of 114 and 431 mgL−1 day−1, respectively, was rich in fatty acids mainly of C16:0, C16:1 and C18:0 in the neutral lipid fraction, the most favoured fatty acids for ideal biodiesel properties. The biodiesel properties met the requirements of fuel quality standards based on empirical estimation. The marine diatoms hold a great promise as feedstock for large-scale biodiesel production along with valuable by-products in a biorefinery perspective, after augmenting lipid and biomass production through biochemical and genetic engineering approaches.
