The ability of two recently isolated actinobacteria, that degrade medium and long chain n-alkanes in laboratory water medium, was investigated in soil microcosms using different standard soils that were artificially contaminated with n-alkanes of different length (C(12)- C(20)- C(24)- C(30)). The two strains, identified as Nocardia sp. SoB and Gordonia sp. SoCp, revealed a similar high HC degradation efficiency with an average of 75% alkane degraded after 28 days incubation. A selectivity of bacteria towards n-alkanes of different length was detected as well as a consistent effect of soil texture and other soil physical chemical characteristics on degradation. It was demonstrated the specific aptitude of these selected strains towards specific environmental conditions.
两种最近分离的放线菌具有在实验室水介质中降解中长链正烷烃的能力，本研究使用不同的标准土壤在土壤微宇宙中进行了研究，这些标准土壤是通过人为添加不同长度的正烷烃（C(12)-C(20)-C(24)-C(30)）而被污染的。两种菌株被鉴定为诺卡氏菌 SoB 和戈登氏菌 SoCp，它们在 28 天的培养后表现出相似的高 HC 降解效率，平均降解了 75%的烷烃。研究还检测到了细菌对不同长度正烷烃的选择性，以及土壤质地和其他土壤物理化学特性对降解的一致影响。研究结果表明，这些筛选出的菌株对特定环境条件具有特定的适应性。
