从沿海烃污染沉积物中分离出一种海洋细菌，并根据其表型和基因型特征将其归为鞘氨单胞菌属。该菌株能够使用烷基化菲- 2-甲基菲作为碳和能量的唯一来源。实验中，在培养基中加入2-甲基菲（0.2 g/l）结晶体。在30℃有氧生长5天后，70%降解，20天后完全耗散。此外，菌株可以降解多种多芳香族化合物，但不能降解脂肪烃。
A marine bacterium isolated from a coastal hydrocarbon-polluted sediment has been described and attributed on the basis of its phenotypic and genotypic characteristics to the genus Sphingomonas sp. This strain was capable of using an alkylated phenanthrene 2-methylphenanthrene, as sole source of carbon and energy. In experiments, 2-methylphenanthrene (0.2 g/l) was added as crystals to the culture medium. After 5 days of aerobic growth at 30 degrees C, 70% was degraded and the complete dissipation occurred after 20 days. Furthermore, the strain could degrade various kinds of polyaromatic compounds, but failed to grow on aliphatic hydrocarbons.
