All rights reserved.Spirulina platensis is a microalgae species that contains phycocyanin, a blue pigment that is widely used in the food, cosmetic and pharmaceutical industries. The objective of this study was to isolate phycocyanin from dried biomass of Spirulina platensis. The optimum extraction was through freezethawing extraction with 0.01 M phosphate buffer pH 7. Purification was done using 50% ammonium sulphate precipitation, dialysis, and gel filtration chromatography. The purity ratio of the purified product was 1.729 (A615/A280). Characterization of isolate, carried out using SDS-PAGE, gave molecular weights of around 15-16 Kda and using infrared spectrophotometry the similarity with the standard phycocyanin spectrum was obtained. Both methods confirmed that the isolate was phycocyanin.[/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][/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]Freeze-thawing,Microalgae,Phycocyanin,Purity ratio,SDS-PAGE,Spirulina platensis[/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]This study was supported by Fundamental Research 2016 DIKTI, Directorate of Higher Education of the Ministry of Research, Technology and Higher Education of the Republic of Indonesia.[/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.5614/j.math.fund.sci.2019.51.2.6[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
