| 摘 要： | 油田中硫酸盐还原菌(SRP)的生长代谢能产生大量H_2S,会引起油藏酸化和微生物腐蚀等严重的生产和环境问题,而关于油田环境中SRP微生物多样性与生理活性的研究仍十分缺乏.为了深入了解我国渤海湾海域高温酸化油藏中SRP代谢特点并探究其潜在危害控制方法,本研究采用厌氧纯培养技术从渤海湾某高温油田采出水中分离筛选到1株耐高温、耐盐的SRP菌株BQ1,研究了其生理特性,并评价了不同杀菌剂和代谢抑制剂对其产H_2S活性的影响.结果表明,菌株BQ1的细胞呈短杆状,大小为(1.2~2.5)μm×(0.5~0.8)μm,有运动性.尽管BQ1与普通脱硫弧菌(Desulfovibrio vulgaris Hildenborough)的16S rRNA基因序列相似性达99%,但两者生理特性具有明显差异.BQ1可在温度为14~70℃(最适30℃)、p H 6.0~9.0(最适7.0)、盐度为0%~10%条件下生长代谢.BQ1可利用甲酸钠、乳酸钠、乙酸盐等多种碳源,能以硫酸盐、亚硫酸盐、硫代硫酸盐或单质硫为唯一电子受体产生H_2S.次氯酸钠(600 mg·L~(-1))、苄基三甲基氯化铵(300 mg·L~(-1))或NaNO_3(800 mg·L~(-1))对BQ1产H_2S活性无明显抑制效果.戊二醛(50 mg·L~(-1))、溴硝醇(30 mg·L~(-1))、二氧化氯(50 mg·L~(-1))或NaNO_2(70 mg·L~(-1))可抑制BQ1产H_2S活性达30 d以上,是控制渤海湾高温油田微生物酸化的潜在有效抑制剂.
