Bismuth sulfite agar

Bismuth sulfite agar

Bismuth sulfite agar is a type of agar media used to isolate "Salmonella" species. It uses dextrose as a primary source of carbon. BLBG and bismuth stop gram-positive growth. Bismuth sulfite agar tests the ability to utilize ferrous sulfate and convet it to hydrogen sulfide. T
