Abstract
Silver resistance was studied in a silver-resistant Pseudomonas stutze ri AG259 strain and compared to a silver-sensitive P. stutzeri JM303 s train. Silver resistance was not due to silver complexation to intrace llular polyphosphate or the presence of low molecular weight metal-bin ding protein(s). Both the silver-resistant and silver-sensitive P. stu tzeri strains produced H2S, With the silver-resistant AG259 strain pro ducing lower amounts Of H2S than the silver-sensitive JM303 strain. Ho wever, intracellular acid-labile sulfide levels were generally higher in the silver-resistant P. stutzeri AG259 strain. Silver resistance ma y be due to formation of silver-sulfide complexes in the silver-resist ant P. stutzeri AG259 strain.
