In this study we used Chlorella vulgaris to remediate anaerobically digested dairy manure wastewater (ADDMW) which contained a high concentration of nitrogen and phosphor. The light intensity of 50, 100 μmol/m2s and sunlight were applied to the microalgal culture. Percentage of reduction in ammonium and orthophosphate content in the media were measured. Protein content in microalgal biomass was measured using hot-TCA method. At the light intensity of 100 μmol/m2s, microalgal productivity in biomass reached its high level i.e. 0.149 ± 0.03 gL-1d-1 with its protein content 10.74 ± 0.63%. However, the highest specific growth rate (0.343 ± 0.034 d-1) with the shortest doubling time (2.028 ± 0,141 d) were reached under sunlight conditions. The reduction rate of ammonium and orthophosphate content in the medium were 36-48 mgL-1h-1 and 5-6.62 mgL-1h-1 respectively in a culture which was inoculated with C. vulgaris. C. vulgaris can be used as phycoremediator for ammonium and orthophosphate, and ADDMW medium can supply C. vulgaris with appropriate nutrients. Moreover, light intensities of 50 and 100 μmol/m2s can be used in the indoor culture of 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=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Anaerobically digested dairy manures,Chlorella vulgaris,Microalgal biomass,Microalgal cultures,Phycoremediation,Pollutants removal,Protein contents,Specific growth rate[/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][/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 author would like to thank the Institute of Research and Community Service of Bandung Institute of Technology (Lembaga Penelitian dan Pengabdian Masyarakat ITB) for providing funding for the implementation of research through the P3MI program in 2018.[/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/10.1088/1755-1315/299/1/012013[/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]
