Weathered crude oil (WCO) removals in shoreline sediment samples were monitored for 60 days in bioremediation experimentation. Experimental modeling was carried out using statistical design of experiments. At optimum conditions maximum of 83.13, 78.06 and 69.92% WCO removals were observed for 2, 16 and 30 g/kg initial oil concentrations, respectively. Significant variations in the crude oil degradation pattern were observed with respect to oil, nutrient and microorganism contents. Crude oil bioremediation were successfully described by a first-order kinetic model. The study indicated that the rate of hydrocarbon biodegradation increased with decrease of crude oil concentrations.
在生物修复实验中，监测了 60 天的岸滩沉积物样品中风化原油（WCO）的去除情况。实验模型采用实验设计的统计方法进行。在最佳条件下，对于初始油浓度为 2、16 和 30 g/kg 的情况下，WCO 的最大去除率分别为 83.13%、78.06%和 69.92%。观察到原油降解模式与油、营养物和微生物含量有显著变化。原油的生物修复可以用一级动力学模型成功描述。该研究表明，随着原油浓度的降低，烃类生物降解的速率增加。
