我们发现，细菌密切相关的Alcanivorax成为优势菌群在石油污染的海水中，当氮和磷营养盐供应充足的数量。Alcanivorax细菌的优势在三种实验条件下得到了证明：（i）在含有重油的海水的分批培养中;（ii）在经历连续海水流动的填充有油涂层砾石的柱中;以及（iii）在模拟用新鲜海水经历潮汐循环的海滩的大规模潮汐通量反应器中。这些结果表明，与Alcanivorax相关的细菌是石油污染海洋环境生物修复的主要参与者。
We found that bacteria closely related to Alcanivorax became a dominant bacterial population in petroleum-contaminated sea water when nitrogen and phosphorus nutrients were supplied in adequate quantity. The predominance of Alcanivorax bacteria was demonstrated under three experimental conditions: (i) in batch cultures of sea water containing heavy oil; (ii) in columns packed with oil-coated gravel undergoing a continuous sea water flow; and (iii) in a large-scale tidal flux reactor that mimics a beach undergoing tidal cycles with fresh sea water. These results suggest that bacteria related to Alcanivorax are major players in the bioremediation of oil-contaminated marine environments.
