在很多海域油田中,生長在50℃以上的微生物是負責環境中有機物質的氧化。近年來,在探討油田酸化方面,產生硫化氫的高溫微生物已逐漸受到重視。本文報導從北海油田的產出水中,高溫硫酸根還原細菌能在55℃和70℃的培養溫度下被增殖。另外,在70℃的培養溫度,一株能利用丁酸作為唯一碳源和能源的嗜高溫硫酸根還原細菌NM2成功地被分離出來,此菌株的生長溫度範圍在55℃和90℃之間,最適生長溫度範圍在65℃和75℃之間。類緣關係分析的結果指出兩株NM2和古細菌中的嗜超高溫硫酸根還原古細菌Archaeoglobus fulgidus VC 16非常相似。依據本文中所培養出來的嗜高溫硫酸根還原細菌的生理生態特徵顯示,這些細菌很可能是油田中硫化氫主要的生產者。
Many oil field environments constitute ecological niches in which thermophilic microorganisms growing above 50℃ are responsible for the mineralization of organic material. More recently, thermophilic sulfidogenic microorganisms have been received more attention to when considering reservoir souring. Here we report the enrichment at 55℃ and 70℃ of thermophilic sulfate reducers from production waters in the North Sea oil field. Additionally, a novel thermophilic sulfate-reducing strain NM2, growing at the temperatures between 55℃ and 90℃ with an optimum between 65℃ and 75℃, was isolated from the 70℃ growth medium with butyrate as a carbon and energy source. Phylogenetically, the thermophilic strain NM2 is closely related to Archaeoglobus fulgidus VC 16. As a consequence of the physiological and ecological characteristics described in this paper, such thermophilic sulfate reducers growing at either 55℃ or 70℃ may play an important role in the biogenic production of hydrogen sulfide in the oil field.
