(having 95.9% similarity to the almost full-length 16S rRNA gene sequence from isolate 1lE25) and
two Erythrobacter species, isolated from an actual crude-oil-polluted
Indonesian sea site, have recently been reported to degrade PAHs
(16). Degrading activity in the genus Rhodovulum has not been
reported previously.
The Altererythrobacter isolate 1lE25 was pigmented, and the
acetone extract of this isolate showed a visible absorption spectrum
with maxima at 454 and 481 nm, closely resembling the spectrum
of zeaxanthin (LipidBank; http://lipidbank.jp/), a major non-polar
carotenoid in Erythrobacter (29). Though aerobic cultures of Rhodovulum
have been reported to be pink to red (30), cells of the
Rhodovulum-related isolates 1R7 and 2R27 did not appear to be
pigmented.
