Abstract
In this study, we report the isolation of denitrifiers from hydrocarbon-contaminated Antarctic soils. Seventy-two isolates were obtained from soils that had received a fertilizer treatment to stimulate hydrocarbon degradation. All isolates, except one, belonged to the genus Pseudomonas. The one exception was a member of the Microbacteriaceae, which was also, coincidentally, the only isolate negative for the nirS gene. The diversity of the 16S rRNA and nosZ genes was assessed by denaturing gradient gel electrophoresis and sequencing. There was a slight correlation between the 16S rRNA and nosZ operational taxonomic units. Surprisingly, many isolates contained nosZ on plasmids and, to the best of our knowledge, this is the first report of nosZ being extra-chromosomally present in Pseudomonas spp. © 2006 Springer-Verlag.
