[Isolation of phenol-degrading bacteria from natural soil and their phylogenetic analysis].

Five bacterial strains capable of utilizing phenol as sole carbon source for growth were isolated from non-contaminated natural soil sample after enrichment in the presence of phenol. They were preliminarily identified according to their phylogenetic analysis and physiological and biochemical characteristics. Strain PHD-2, PHD-4 and PHD-5 belonged to the genera of Ralstonia, Acinetobacter and Microbacterium respectively; strain PHD-1 and PHD-3 were from the genus of Pseudomonas. Homology comparing of their 16S rRNA gene sequences and phylogenetic analysis displayed the high biodiversity of phenol-degrading microorganisms in the natural soil.
