N 等4 从Kazakhstan 和West Siberia 油田分离到嗜热的烃氧化菌。菌株杆状、运动,内生芽孢,严格好氧,生长温度为4070 。最适生长条件:pH ,68 ,温度5560 ,NaCl 浓度510gPL。该菌鉴定为嗜热嗜油芽孢杆菌。微生物石油降解微生物石油降解综述Abstract: Oil as a important energy has been one of the

代谢产生H2S酸性气体,不但可以提高地层压力,还可以溶解碳酸盐岩层,促进原油的释放和增大地层的渗透率。某些菌种还可以降解石油中的组分,改善原油的流动性,提高原油采收率。但这类菌群的活动使产出的油气中含有硫化氢,增加生产设施的腐蚀问题,并带来严重的生产安全问题。因为其有害性,SRB 是油田水中研究得最详细的细菌群落。微生物石油降解微生物石油降解综述Abstract: Oil as a

产甲烷菌为严格厌氧菌。从油层深部分离产甲烷菌直到最近才有报道。在低盐度到高盐度的中温油藏中都有产甲烷菌存在。一般认为高温高盐环境使得微生物群落急剧减少。Borzenkov 等研究表明产甲烷菌随盐度增加而减少1 。此外,甲胺的浓度(一种产甲烷底物) 随地层水矿化度增加而增加。嗜甲基菌从盐度达140gPL 的开发井样品中分离出。该菌轻度嗜盐,利用甲醇、甲胺和二甲基硫化物作底物。另一种利用甲醇和三甲基胺的中度嗜盐产甲烷菌从含90gPL NaCl 的法国Alsacian 油田中分离。. 微生物石油降解微生物石油降解综述Abstract: Oil as a important energy has been one of the countries all over the world widely

石油是多种烃类组成的混合物,包括烷烃、环烷烃和芳烃等。在石油烃类中,以直链的烃类最易被氧化,芳烃和环烷烃的氧化较难。微生物对直链烃的氧化有多种方式:单末端氧化、双末端氧化和次末端氧化等。其中单末端氧化是最主要的方式。如微生物对正链烷的氧化,首先是在单氧化酶系的酶促下,将氧分子的一个氧原子加入到烃中去,使其形成相应的醇,另一个氧原子与烃类脱下的氢结合形成水。已知在细菌中有两种类型的氧化酶系,其氧化作用如反应图式。 正链烷被氧化成相应的醇后,在脱氢酶的作用下,接着被氧化成相应的醛和酸。脂肪酸再通过氧化和三羧酸循环进一步氧化成二氧化碳和水。苯是芳烃的代表,微生物对苯的氧化,首先是在氧化酶系的作用下,将氧的分子加到苯环上形成邻苯二酚,然后经一系列酶促反应,相继生成顺-顺粘糠酸、-酮基巳二酸、琥珀酸等。烃类被微生物氧化后,约有2070的组分转化为微生物细胞的组分。3.1影响降解的因素

4种不同的原油中接种含有烃类氧化菌的相同水样,经培育,微生物的种类组成出现了差异。又据试验,中温菌对柴油在20C时的氧化速度比10C时快3倍,而在5C时几乎不发生降解作用。在海水中加入氮和磷,有利于烃类微生物的繁殖,促进对烃类的降解作用。大多数烃类微生物降解石油需要氧,理论上推算,氧化 1升原油大约要消耗3.2105升海水中的溶解氧。据佐贝尔计算,在适宜条件下,细菌氧化海水中油的速率可达到100960毫克/(米3天),入海石油的30可被微生物降解。4防治试验 微生物石油降解微生物石油降解综述Abstract: Oil as a important energy has been one of the countries all over the world widely

由于石油含有成千上百种烃,一种细菌又只能降解一种或几种烃,因此要消除海上油污必须添加微生物的混合培养物。据试验,若在添加烃类微生物混合培养物的同时,又加入含氮和磷的营养剂可在几天内降解原油中6080的烃类。4.2 用“超级微生物”消除油污。微生物石油降解微生物石油降解综述Abstract: Oil as a important energy has been one of the

的降解效果不显著,部分研究者提出了微生物的厌氧降解和共代谢处理等修复方法,且逐渐成为该领域的研究重点。这些方法较一般好氧修复法有特别的效果与优越性,有望得到推广和应用。此外,人们还较全面地探讨和分析了各种影响微生物修复效果的因素,研究了减少影响提高降解的措施,对控制微生物修复受石油污染土壤技术有很强的指导意义。但由于微生物修复受石油污染土壤是一个复杂的过程,对其中许多的机理和过程尚未完全明确,而且由于各种环境条件的复杂性,该领域的研究还需进一步的拓宽和深入。微生物石油降解微生物石油降解综述Abstract:
