1996年，海皇后号搁浅后，英国米尔福德港的Bullwell湾搁浅了福蒂斯原油和重质燃料油混合物，研究了生物修复方法。采用三份的随机区组设计来测试两种生物修复处理的效果：每周施用溶解在海水中的矿物质营养素和单次施用缓释肥料。每种处理提供等量的氮和磷。残留碳氢化合物浓度归一化到生物标记物17α(H),21β(H)-藿烷的浓度表明，两个月后，处理过的试验区的石油生物降解程度显著高于对照组（p<0.001）。平均而言，在营养改良过的地块中，油的降解程度比对照组高出37%。没有证据表明生物修复处理增加了含油沉积物的毒性。结果表明，生物修复技术可用于处理原油和重质燃料油混合物。
Bioremediation was investigated as a method of treating a mixture of Forties Crude Oil and Heavy Fuel Oil stranded on Bullwell Bay, Milford Haven, UK after the grounding of the Sea Empress in 1996. A randomised block design in triplicate was used to test the efficacy of two bioremediation treatments: a weekly application of mineral nutrients dissolved in seawater and a single application of a slow-release fertilizer. Each treatment supplied an equivalent amount of nitrogen and phosphorus. Concentrations of residual hydrocarbons normalised to the biomarker 17α(H),21β(H)-hopane showed that after two months the oil was significantly (p<0.001) more biodegraded in the treated plots than in the controls. On average, the oil in the nutrient amended plots was 37% more degraded than that found in the controls. There was no evidence that the bioremediation treatments increased the toxicity of the oiled sediment. The results confirm that bioremediation can be used to treat a mixture of crude and heavy fuel oil on a ...
