Ruthenium has no known biological function, but ruthenium is present in the human body at a higher concentration than the essential element cobalt (Emsley, 1989). The nuclear fission products 103Ru and 106Ru are minor constituents of nuclear power plant effluents, and the potential for microorganisms to accumulate ruthenium isotopes has been explored (Zharova, 1961; Gibson et al, 1986). Isolated Bacillus subtilis cell walls have been shown to bind Ru3+ with high affinity (Beveridge, 1978).
