Bacteria with limited genomic cross-hybridization were isolated
from soil contaminated with C5+, a mixture of hydrocarbons, and
identified by partial 16S rRNA sequencing. Filters containing denatured
genomic DNAs were used in a reverse sample genome probe (RSGP)
procedure for analysis of the effect of an easily degradable compound
(toluene) and a highly recalcitrant compound (dicyclopentadiene [DCPD]) on community composition. Hybridization with labeled
total-community DNA isolated from soil exposed to toluene indicated
enrichment of several Pseudomonas spp., which were
subsequently found to be capable of toluene mineralization.
Hybridization with labeled total-community DNA isolated from soil
exposed to DCPD indicated enrichment of a Pseudomonas sp.
or a Sphingomonas sp. These two bacteria appeared capable
of producing oxygenated DCPD derivatives in the soil environment, but
mineralization could not be shown. These results demonstrate that
bacteria, which metabolize degradable or recalcitrant hydrocarbons, can
be identified by the RSGP procedure.
