Abstract：
:The photosynthetic sulfur bacterium, Chromatium vinosum, was cultured in inorganic photographic processing solutions containing silver thiosulfate complex salt (AgNa3(S2O3)2) under light. It was found that Chromatium was resistant to Ag and accumulated granular silver in the membrane during growth. The amount of Ag accumulated in the cells depended on the initial concentrations of the Ag salt in the culture solution. When the concentration of Ag was 300 mg/l, the bacteria accumulated Ag as high as 30% of the dry cell weight. The size of the granules was 0.1 to 0.3 μm. Results from X-ray microanalysis indicated that these granules consisted mostly of Ag(o) with small fractions of Ag2S and AgCl.
