A facultative anaerobic species Serratia marcescens ACE2 isolated from the corrosion products of diesel transporting pipeline in North West, India was identified by 16S rDNA sequence analysis. The role of Serratia marcesens ACE2 on biodegradation of diesel and its influence on the corrosion of API 5LX steel has been elucidated. The degrading strain ACE2 is involved in the process of corrosion of steel API 5LX and also utilizes the diesel as an organic source. The quantitative biodegradation efficiency (BE) of diesel was 58%, calculated by gas-chromatography-mass spectrum analysis. On the basis of gas-chromatography-mass spectrum (GC-MS), Fourier Transform infrared spectroscopy (FTIR) and X-ray diffractometer (XRD), the involvement of Serratia marcescens on degradation and corrosion has been investigated. This basic study will be useful for the development of new approaches for detection, monitoring and control of microbial corrosion.
通过16S rDNA序列分析鉴定出一株从印度西北部柴油运输管道腐蚀产物中分离得到的兼性厌氧物种粘质沙雷氏菌ACE2。阐明了粘质沙雷氏菌ACE2对柴油生物降解的作用及其对API 5LX钢腐蚀的影响。降解菌株ACE2参与了API 5LX钢的腐蚀过程，并且还利用柴油作为有机源。通过气相色谱 - 质谱分析计算得出柴油的定量生物降解效率（BE）为58%。基于气相色谱 - 质谱（GC-MS）、傅里叶变换红外光谱（FTIR）和X射线衍射仪（XRD），研究了粘质沙雷氏菌对降解和腐蚀的影响。这项基础研究将有助于开发检测、监测和控制微生物腐蚀的新方法。
