Silver toxicity to Pseudomonas stutzeri AG259 was strongly dependent on the NaCl concentration in the medium, which reduced the availability of Ag+ by precipitation as AgCl. Accumulation of Ag by growing cultures was low being less than or equal to 7.5 nmol (mg dry mass)-1 over all treatments examined. The presence of NaCl in the growth medium did not markedly affect the amounts of Ag accumulated by the cells but influenced toxicity as manifest by a lag period which was greatest at low NaCl… CONTINUE READING
