Descrizione

Descrizione generale

Sulfite Polymyxin Sulfadiazine (SPS) Agar contains a broad spectrum of nutrients. Most clostridia (including C. perfringens) reduce sulfite to sulfide, which reacts with iron citrate and causes the colonies to turn black. Other sulfite-reducing microorganisms are suppressed by polymyxin and sulfadiazine (sulfapyrimidine). The low sulfite content allows the growth of even sulfite-sensitive clostridia, which exhibit an adequate blackening of the colonies.

Applicazioni

SPS agar is suitable for the isolation and enumeration of Clostridium perfringens and Clostridium botulinum in all types of foodstuffs.
