Pseudomonas stutzeri, isolated from crude oil-contaminated soil, was used to degrade diesel oil. Of three surfactants, 120 mg rhamnolipids 1(-1) significantly increased degradation of diesel oil giving 88% loss after 14 days compared to 54% loss without the surfactant. The system with rhamnolipids was characterised by relatively high particle homogeneity. However, the addition of saponins to diesel oil caused the cells to aggregate (the polydispersity index: 0.542) and the biodegradation of diesel oil was only 46%. The cell yield was 0.22 g l(-1).
从受原油污染的土壤中分离到的恶臭假单胞菌被用于降解柴油。在三种表面活性剂中，120mg 鼠李糖脂 1(-1) 显著提高了柴油的降解率，在 14 天内与无表面活性剂相比，降解率从 54%提高到 88%。添加鼠李糖脂的体系具有相对较高的颗粒均一性。然而，向柴油中添加皂素会导致细胞聚集（多分散指数：0.542），柴油的生物降解率仅为 46%。细胞产率为 0.22g/L。
