Sulfate Reducing Bacteria (SRB) is a bacteria that frequently caused corrosion in steel surface by creating pits. In this research, the corrosion test was done by using one species of SRB which is Desulfovibrio Baculatus. The water that contains bacteria growth medium (API Sulfate Broth) is used as a media for API 5L X65 steel corrosion test. Sulfate for the growing of SRB was added in the solution for 8.56, 17.12, 42.8 and 85.64 ppm, and the immersion test was carried out for 1, 7, 14 and 21 days. The source of sulfate is FeSO4.7H2O, and this compound was also considered as a source of Iron (II). The result shows that the weight loss increased with immersion period. Between 7 to14 days of immersion time, the increase of weight loss that represents a corrosion rate attains the highest condition and decrease again after 14 days. Morphologic observation revealed that the corrosion product consists of Iron Oxide and biological deposits that formed at the beginning of corrosion test, and continued with the formation of Iron Sulfide. The formation of Iron Sulfide was associated with the increase of corrosion rate. © (2014) Trans Tech Publications, Switzerland.[/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]Desulfovibrio,FeSO4 content,Immersion,MIC,SRB[/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]Desulfovibrio baculatus,FeSO4 content,Immersion,MIC,SRB[/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][/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/10.4028/www.scientific.net/AMR.858.177[/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]
