Abstract:
Transconjugants of plasmid pJP4, originating from an agar plate mating of a Pseudomonas putida donor with an activated sludge-derived microbial community, were isolated and identified by partial 16S rDNA sequencing. The transconjugant strains belonged to a variety of genera of the alpha-, beta-, gamabeta- and gamma-classes of the Proteobacteria, mostly to the families Rhizobiaceae and Comamonadaceae and the genus Stenotrophomonas. Only P. putida and Delftia spp. strains were able to grow on 2,4-D as the sole carbon source.
