Eight type of biosurfactants extracted from indigenous bacterial isolates were investigated for their ability to eradicate or inhibit biofilm growth. Materials and Method: Biofilm assays were performed using broth microdilution method in microtiter plate 96 wells. The parameters used were Minimum Inhibitory Concentration (MIC), Minimum Biofilm Inhibitory Concentration (MBIC) and Minimum Biofilm Eradication Concentration (MBEC). MIC and MBIC were tested on biofilm consortium liquid culture, while MBEC was tested on preformed biofilm. Results: Biosurfactant of isolate F3 exhibited the highest eradication level (68.3%) at 100 µg mLG1. The MIC, MBIC50, MBIC90 and MBEC50 were observed at 50, 25, 25 and 25 µg mLG1, respectively. Based on these results of this study, biosurfactants produced by isolate F3 was potential to be an alternative biocide that can eliminate biofilm-forming microbial consortium. Conclusion: This study affirms that biosurfactant is not only useful for enhancing oil recovery in petroleum industry. It is also potential to be an alternative biocide to eliminate biofilm associated with biocorrosion.[/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]Biocide,Biocorrosion,Biofilm eradication,Biosurfactant,MBEC,MBIC,MIC[/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 authors would like to thank ITB for funding this research through “Program Penelitian, Pengabdian kepada Masyarakat, dan Inovasi (P3MI) ITB 2017” and Qonita Afinanisa for editing the manuscript.[/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/10.3923/jest.2018.104.111[/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]
