结果表明，这两种放线菌都能以变压器介质油为惟一碳源进行生长繁殖，前者为革兰氏染色阴性，培养早期断裂为杆状；后者为革兰氏染色阳性，有明显的分枝菌丝。

Results Infected by this peptide, cell viability decreased 28.9%. Under light microscope, cells were shrinked and rounded, many cells were divorced from plate wall, some neuraxon shortened and broke. Apoptotic cells which nucleolus shrinked and rounded could be coloured orange by fluorescent colouration. Under electron microscope, chromatin gathered along the inside of the nuclear membrane, vacuole bodies appeared. Apoptotic peak was detected by flow cytometry and the ladder band appeared in DNA electrophoresis.

结果：细胞接触肽段后存活率下降28.9％；光镜下可见细胞贴壁不良，胞体缩小，细胞突起断裂缩短；荧光染色可见细胞突起缩短、胞核固缩、胞质染成橘红色的凋亡细胞；电镜下可见胞质中出现空泡样结构，细胞染色质浓集于核膜内侧并裂解成碎块状；流式细胞仪检测细胞出现亚二倍体峰，DNA电泳出现梯状带。
