BMRI-2, Rossendorf/Dresden, Germany (30 August - 1 September 2000).

Clearly, there is much left to be understood about microbial processes and interactions with metals, but much progress has been made, and the multidisciplinary approach of groups who are studying both the microbial populations and the chemistry of biotransformations of metals by bacteria will ensure rapid progress in our understanding of these issues. Several major points from different speakers summarize this meeting and are usefully reiterated at this point: Toxic metal ions, unlike organic pollutants, are immutable, and their bioavailability is a critical feature of their toxicity. The mobility, transport and fate of toxic metals and radionuclides in the environment are dependent on chemical and geochemical processes in which micro-organisms are intimately involved. Metals can be mobilized as well as immobilized by microorganisms. Metal/radionuclide valencies and chemical properties are critical to their environmental mobility. Bacterial- or fungal-metal interactions will be complicated by the presence of other pollutants. The identification of bacteria from environmental samples should not rely on one methodology, as these have been shown to be biased. Sonja Selenska-Pobell organized both BMRI-1 in 1998 and BMRI-2, which had well over 100 participants from Europe, Russia, USA and Japan in attendance. Thirty-one oral presentations were given, and over 30 posters were displayed over two poster sessions. BMRI-3 is provisionally planned for 2002 at GBF, Braunschweig, Germany.
