Epiphytic microorganisms degrading aromatic hydrocarbons from the phyllosphere of urban woody plants


From the leaves of three urban trees (Tilia sp., Acer sp., and Fraxinus sp.), 180 strains degrading phenanthrene, naphthalene, and salicylate were isolated by direct plating and enrichment cultures. The leaves of each tree species were characterized by a specific profile of aromatic hydrocarbon-degrading microflora. Members of the type Actinobacteria were predominant in the case of direct plating on media with phenanthrene and naphthalene. Enrichment cultures with phenanthrene and salicylate were shown to yield microbial consortia, the composition of which changed with time. Members of the type Proteobacteria were predominant in these consortia. No plasmids of polycyclic aromatic hydrocarbon degradation of the P-7 and P-9 incompatibility groups were revealed in the studied strains.
