说明
一般描述
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.
应用
SPS agar is suitable for the isolation and enumeration of Clostridium perfringens and Clostridium botulinum in all types of foodstuffs.
特点和优势
GranuCult® offers superior granulated culture media
Safe and sustainable due to reduced risks associated with fine dust and toxic substance inhalation, resulting in a safer work environment
Excellent wettability, solubility, and free-flowing properties
Convenient, with minimal component separation and clumping, even under warm or humid conditions
High batch-to-batch reproducibility
Prolonged shelf life of up to five years
High number of test strains exceeding all regulatory demands
Granulation technology allows many supplements to be included, with no need to add these separately
