Anthracene is a PAH that is not readily degraded, plus its
degradation mechanism is still not clear. Thus, two strains
of anthracene-degrading bacteria were isolated from longterm
petroleum-polluted soil and identified as Sphingomonas
sp. 12A and Pseudomonas sp. 12B by a 16S rRNA
sequence analysis. To further enhance the anthracenedegrading
ability of the two strains, the biosurfactants
produced by Pseudomonas aeruginosa W3 were used,
which were characterized as rhamnolipids. It was found
that these rhamnolipids dramatically increased the solubility
of anthracene, and a reverse-phase HPLC assay showed
that the anthracene degradation percentage after 18 days
with Pseudomonas sp. 12B was significantly enhanced from
34% to 52%. Interestingly, their effect on the degradation by
Sphingomonas sp. 12A was much less, from 35% to 39%.
Further study revealed that Sphingomonas sp. 12A also
degraded the rhamnolipids, which may have hampered the
effect of the rhamnolipids on the anthracene degradation.
