hierarchical_section_title: Bismuth sulfite agar
context_page_description: Bismuth sulfite agar is a type of agar media used to isolate Salmonella species. It uses glucose as a primary source of carbon. BLBG and bismuth stop gram-positive growth. Bismuth sulfite agar tests the ability to use ferrous sulfate and convert it to hydrogen sulfide.
  Bismuth sulfite agar typically contains:
  1.6% bismuth sulfite Bi₂(SO₃)₃
  1.0% pancreatic digest of casein
  1.0% pancreatic digest of animal tissue
  1.0% beef extract
  1.0% glucose
  0.8% dibasic sodium phosphate
  0.06% ferrous sulfate • 7 water
  pH adjusted to 7.7 at 25 °C
  This medium is boiled for sterility, not autoclaved.
