Abstract
Diatoms are a major storehouse of valuable fucoxanthin and polyunsaturated fatty acids, with enormous nutraceuticals and biofuel potential. Three marine diatom species isolated from the southern coast of India has been screened and their results show that highest biomass concentration and fucoxanthin yield was obtained in Chaetoceros sp. as 0.217 g L−1 and 0.403 mg L−1 respectively. Lipid % as dry cell weight was maximum in Thalassiosira sp. (52%) followed by Skeletonema sp. (44%) and Chaetoceros sp. (22%). However, protein and secondary metabolites content besides the total antioxidant activity was estimated highest in Skeletonema sp. Having strong inhibition zones of 18–20 mm against all the five strains of bacteria also highlights the highest antibacterial prospect in Skeletonema sp. This work manifests the plasticity of diatoms and may provide useful insights for further species-specific selection for large-scale production of eicosapentaenoic acid, docosahexaenoic acid, fucoxanthin and other metabolites with potential health benefits.
