Industrial sites can be considered as a new source of biodiversity. Microorganisms belonging to these biotopes represent potential solutions and cures for damaged areas. In the present work we explore different areas of a historical metallurgic site dismissed in the early 90s (Bagnoli-Naples, Italy), in order to compare the native microbial communities in relation with the contaminants and the ecotoxicity levels detected. All the three different areas studied show a biological respiratory activity and harbour diverse microbial communities, a fraction of which is culturable and harbour resistances to heavy metals. The biological respiratory activity, the metabolic profile at community-level and the total heterotrophic bacterial population result inversely correlated to the detected ecotoxicity. The most widespread resistances are to Cr6+ and Pb2+, but also Cd2+ and Co2+. As these metals are present in very low concentrations in nature, usually metabolic genes for these metals are unusual too. Thus these observed resistances are the result of a specific selective process exercised by the unusual excessive presence of these elements in this polluted site. © 2006 Wiley-VCH Verlag GmbH & Co.
