| 摘 要： | 研究了自行分离的两株原油降解菌SYl和SY2的降解特性．结果表明，在不加任何营养盐下，菌株SYl和SY2的原油降解率分别达到41．3％和42．6％，实际海水的盐含量、温度、pH值和氧溶解量能够满足菌株降解原油的需求，并且具有较宽的底物利用范围．建立了菌株SYl和SY2降解原油的动力学模型，该模型基本符合Miehealis-Menten方程．

| Abstract: | The biodegragation efficiency of two petroleum-degrading strains SY1 and SY2 was investigated with synthetic seawater. Experimental results indicated that their biodegradation rates were 41.3% and 42.6% respectively without addition of minor nutrients. Both the strains can adapt to typical ocean conditions including temperature, pH and dissolved oxygen, and also degrade a broad spectrum of hydrocarbon substrates. The kinetic model of biodegradation of crude oil by these two strains were also established, which abides by Michealis-Menten equation. |
