After medium evaluation, significant Thalassiosira sp. cell growth was observed in both Walne and enriched seawater media, but not in plain seawater medium. The microalgae grew well in alkaline condition (pH range of 8.0-8.8). The average biomass density cultured in Walne and enriched seawater media on the 6th day was 4.36 and 2.50gL -1, respectively. Based on ESI-IT-MS spectra, the TAGs of algal oil were identified as POP, POO, and SOO, and the FAMEs as oleic acid methyl ester. The oil productivity of Thalassiosira sp. cultured in Walne and enriched seawater media were 150 and 290μLL -1d -1, respectively. The density and kinematic viscosity of Thalassiosira sp. biodiesel were 0.857gmL -1 and 1.151mm 2s -1. © 2011 Elsevier Ltd.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Algal oil,Alkaline conditions,Biomass density,Growth characteristic,Marine diatoms,Marine microalgae,Micro-algae,Oleic acid methyl ester,pH range,Product property,TAG,Thalassiosira sp[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Biodiesel,Oil productivity,TAG,Thalassiosira sp.,Tropical marine microalgae[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The financial support from the Southeast Asian Regional Center for Graduate Study and Research in Agriculture – Seed Fund for Strategic Research and Training Program and from the Ministry of National Education of the Republic of Indonesia through the Beasiswa Unggulan Program are gratefully acknowledged.
