A strain of Pseudomonas stutzeri was isolated form an enrichment of perchlorate reducing bacteria from the formation water collected from an Indian coalbed which solubilized coal and produced copious amount of biosurfactant when coal was added to the medium. It produced maximum biosurfactant with lignite coal followed by olive oil and soybean oil which was able to emulsify several aromatic hydrocarbons including kerosene oil, diesel oil, hexane, toluene etc. Haemolytic test, growth inhibition of Bacillus subtilis and FTIR analysis showed rhamnolipid nature of the biosurfactant. The stability of the coal induced biosurfactant in pH range of 4-8 and up to 25% NaCl concentration and 100 °C temperature suggests that due to its ability to produce biosurfactant and solubilize coal P. stutzeri may be useful in the coalbed for in situ biotransformation of coal into methane and in the bioremediation of PAHs from oil contaminated sites including marine environments.

从印度煤层收集的地层水中分离出一株stutzeri假单胞菌,富集高氯酸盐还原细菌,当将煤添加到培养基中时,该地层水溶解了煤并产生了大量的生物表面活性剂。它用褐煤和橄榄油和大豆油产生最大的生物表面活性剂,能够乳化几种芳香烃,包括煤油,柴油,己烷,甲苯等。溶血试验,枯草芽孢杆菌的生长抑制和FTIR分析显示了生物表面活性剂的鼠李糖脂性质。煤诱导的生物表面活性剂在4-8的pH范围内以及高达25% 的NaCl浓度和100 °C的温度下的稳定性表明,由于其能够产生生物表面活性剂和溶解煤P. stutzeri可能在煤层中用于将煤原位生物转化为甲烷以及在PAHs的生物修复中石油污染场地,包括海洋环境。
