| 摘 要： | 从塔里木某输油管线中分离出一株硫酸盐还原菌(SRB),并对其生理生化特性及腐蚀行为进行研究。结果表明:该株SRB在不同碳源培养基中生长速率存在明显差异,最适生长温度为35℃左右,最适p H在7.5左右,最适Na Cl浓度在0.5%左右;接菌溶液中Q235钢片的腐蚀速率达到0.043 6 mm/a,远大于其在无菌溶液中的腐蚀速率。

Study on Physiological and Biochemical Characteristics and Corrosion Behavior of Sulfate Reducing Bacteria Isolated From Oil Pipeline |

| Abstract: | A sulfate reducing bacteria (SRB) was isolated from a petroleum pipeline in Tarim. And its physiological and biochemical characteristics and corrosion behavior were studied. The results show that growth rate of the SRB strain has obvious difference in different carbon source culture mediums, the most suitable temperature for the growth of SRB is about 35 ℃, the optimal pH is about 7.5, the optimum concentration of NaCl is 0.5%; and the corrosion rate of Q235 steel in solution with SRB is 0.043 6 mm/a, which is much higher than that in the sterile solution. |
