According to their 16S rRNA gene analyses, and the physiological properties, the isolated XS1 was identified as Brevibacillus sp; and the isolated XS2 and XS3 were identified as Geobacillus pallidus. The three isolates could degrade crude oil and had effective emulsification activity. All the isolates can grow at a high temperature, with the optimal growth temperature of XS2 being 60℃, and have a wide adapt-ability to pH, in the range of 5.5—9.5. NaCl concentration has no obvious effect on the growth of three strains. Meanwhile, XS2 has an effective emulsification activity; and the emulsification activity has no apparent change at 100℃ and under 20% salinity conditions. The analysis of chromatogram characteristic changes of crude oil during biodegradation process shows that the strain XS2 can degrade not only the light-weight components of crude oil, but also its heavy-weight components, it enhances the fluidity of crude oil, and the quality of crude oil is also improved. It will have a good prospect in microbial enhanced oil recovery., authors=XU Shuang^1,2, HUANG Zhiyong², LU Fuping¹, WANG Yongli³, authorsList=XU Shuang;HUANG Zhiyong;LU Fuping;WANG Yongli, authorCompany=1.

XS1）和白色土芽孢杆菌（Geobacillus pallidus XS2，XS3）。3株分离菌均可在50℃高温下生长，其中菌株XS2的最适生长温度为60℃，在pH值为5.5—9.5范围内均可生长，有良好适应性，盐浓度对菌株生长影响不大。菌株XS2同时还具有很好的乳化活性和乳化稳定性，在100℃高温，20%盐浓度下，乳化活性均无明显变化。通过对原油降解过程中色谱特征分析，菌株XS2不仅可降解原油组分中的轻质组分，而且还能很好地降解原油中重质组分，提高原油流动性，原油品质也得到大大改善，可见菌株XS2是一株潜在驱油微生物，在微生物采油中具有较好的应用前景。,
