It revealed that the nitrate addition could suppress the growth of SRB and stimulate the growth of nitrate-reducing bacteria (NRB). It is not quite clear, however, whether NRB could lead to souring in oil fields and Microbiologically Influenced Corrosion (MIC). In this study, we isolated NRB and investigated the effect of isolated NRB on souring and MIC. Based on 16S ribosomal RNA identification, isolated NRB belongs to the genus Marinobacter and was named Marinobacter YB03. This bacterium is identified as NRB with sulfate reducing ability. Severe pitting corrosion was found on the carbon steel coupon associated with YB03. Therefore, YB03 promotes souring and corrosion.[/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]16S ribosomal RNA identifications,Marinobacter,Microbiologically influenced corrosions,Nitrate-reducing bacteria,Souring,Sulfate reducing,Sulfate reducing bacteria,Sulfate reduction[/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]Marinobacter,Microbiologically influenced corrosion,Pitting,Souring,Sulfate reduction[/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]Samples were provided by the International Petroleum Exploration Corporation (INPEX, Tokyo, Japan).[/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/10.1016/j.bej.2020.107520[/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]
