| 摘 要： | 从１０００份土壤和水等样品中，经富集培养、血平板分离、摇瓶培养和排油活性测定等方法筛选出１０株能产生各种生物表面活性剂的菌株（包括细菌，酵母和霉菌）。其中一株细菌产海藻糖脂，一株细菌产鼠李糖脂，两株细菌分别产长碳链不饱和脂肪酸和壬二酸，两株酵母产生的脂多糖具有良好的乳化性能

| Abstract: | Microorganisms capable of producing biosurfactants can be isolated by a series of steps including hydrocarbon enrichment culture, hemolytic activity assay on blood agar plates and oil displacement activity assay etc. Ten strains(including bacteria, yeasts and fungi) were isolated with higher surface activity from 1000 samples from soil, sludge, waste water etc. Two strains of bacteria produced rhamnolipids and trehaloselipids respectively. One strain of bacterium produced long chain unsaturated carboxylic acid and another produced azelaic acid. Two strains of yeasts produced lipopolysaccharides with excellent emulsification property. |
