In　this　work,　the　effects　of　different　nutrient　contents　in　simulated　soil　solution　containing　sulfate-reducing　bacteria　(SRB)　on　the　corrosion　of　X80　pipeline　steel　were　studied.　The　highest　amount　of　sessile　SRB　was　found　in　the　initial　medium　concentration　of　1/3,　followed　by　the　concentration　of　10%,　and　the　lowest　in　the　simulated　soil　solution　without　culture　medium.　However,　the　biofilm　formed　in　the　simulated　soil　solution　without　culture　medium　had　the　strongest　adhesion　and　corrosiveness,　with　X80　steel　having　the　highest　corrosion　rate,　which　was　approximately　7.2　times　of　the　initial　medium　concentration　of　1/3.　The　research　results　have　a　positive　role　in　promoting　the　development　of　SRB　corrosion　prevention　technology　for　buried　pipeline.
