| 摘 要： | 从原油污染的士样中筛选得到了一株产生物表面活性剂的菌株RDY7-l,经细菌生理生化试验和16SrDNA基因序列分析初步鉴定为地衣芽孢杆菌(Bacillus licheniformis),菌株RDY7-1的主要发酵产物通过离子性检测、糖、氨基酸等组分分析初步定性为脂肽类化合物. |
| 关 键 词： | 地衣芽孢杆菌 筛选 鉴定 脂肽 |

| Abstract: | Lipopeptide producing strain RDY7-1 was isolated and purified from oil field.The morphology,physiological and biochemical properties of bacteria and 16SrDNA gene sequence demonstrated that RDY7-1 was closely related to the genus Bacillus licheniformis.The main metabolites of strain RDY7-1 were characterized as lipopeptide by ion detection,sugar and amino acid composition analysis. |
| Keywords: | Bacillus licheniformis screening identification lipopeptide |
