Abstract

The microorganisms Pseudomonas aeruginosa, Pseudomonas putida and Bacillus subtilis, Bacillus cereus, Bacillus licheniformis and Bacillus laterospor strains are used as biological agents in the biodegradation process of a model mixture of hydrocarbons, as well as in a mixture of emulsifiers. These consist of AT 7, Tween-80, L-10 or Lutensol GD 70. The examination of hydrocarbon biodegradation was carried out using aseptic solutions and water samples from the River Warta in Poland. Significant effectiveness of hydrocarbon biodegradation of the examined bacterial strains and their mixtures in both was observed after seven days of biodegradation. The effectiveness of biodegradation depends on the type of emulsifier used. Results of the biodegradation experiments indicate the important role of the natural emulsifiers which are produced by the Pseudomonas aeruginosa and Pseudomonas putida strains.

乳化剂对假单胞菌和芽孢杆菌降解碳氢化合物的影响

微生物铜绿假单胞菌、恶臭假单胞菌和枯草芽孢杆菌、蜡样芽孢杆菌、地衣芽孢杆菌和芽孢杆菌菌株被用作生物制剂，用于碳氢化合物模型混合物的生物降解过程，以及乳化剂混合物。这些包括at7, Tween-80, L-10或Lutensol GD 70。使用无菌溶液和波兰瓦尔塔河的水样进行了碳氢化合物生物降解的检查。经过7天的生物降解，观察到所检测的细菌菌株及其混合物在两者中的生物降解效果显著。生物降解的效果取决于所用乳化剂的类型。生物降解实验结果表明，铜绿假单胞菌和腐臭假单胞菌产生的天然乳化剂具有重要作用。
