SPS AGAR (PERFRINGES SELECTIVE AGAR SEG ANGELOTTI) MERCK
RENDIMENTO 40,0g/l GRANULADO
EMBALAGEM 500G
Mode of Action
Sulfite Polymyxin Sulfadiazine Agar contains a broad spectrum of nutrients. Sulfite is reduced by most clostridia (including Cl. perfringens) to sulfide, which reacts with iron citrate and causes the colonies to turn black. Other sulfite-reducing microorganisms are largely suppressed by polymyxin and sulfadiazine (sulfapyrimidine). The low sulfite content allows growth of even sulfite-sensitive clostridia which also exhibit an adequate blackening of the colonies (PUT et al. 1961; BEERNS et al. 1961).
Typical Composition (g/litre)
Peptone from casein 15.0;
yeast extract 10.0; iron(III) citrate 0.5;

Polymyxin B sulfate 0.01;
sodium sulfadiazine 0.12;
agar-agar 13.9.
Preparation
Suspend 40 g/litre, autoclave (15 min at 121 °C).
pH: 7.0 ± 0.2 at 25 °C.
