Description
Selenite Cystine Broth (SC) – 10ml Tubes
Overview: Introducing our Selenite Cystine Broth (SC), a specialized 10ml selective enrichment medium designed for the isolation and cultivation of Salmonella species, particularly Salmonella enterica serotype Typhimurium. Packaged in convenient, leak-proof plastic tubes, this product is ideal for laboratories focusing on microbiological testing and food safety.
Key Features:
- Product Specification: 10ml per tube, 20 tubes per box
- Packaging: Individually packed to ensure sterility and prevent contamination
- Application: Perfect for selective enrichment culture of Salmonella spp.
Composition and Functionality: Our Selenite Cystine Broth contains essential nutrients that facilitate bacterial growth. Protein peptone provides both carbon and nitrogen sources, supporting the proliferation of Salmonella and inhibiting unwanted bacterial species. The inclusion of lactose serves as a fermentable carbohydrate, while sodium selenite effectively suppresses most Gram-positive bacteria and non-Salmonella Gram-negative intestinal flora. Additionally, phosphate acts as a buffering agent, and L-cystine acts as a reducing agent, optimizing conditions for microbial growth.
Microbiological Sensitivity Testing: To validate the effectiveness of our SC broth, we recommend inoculating the following quality control strains under aerobic conditions at 36±1°C for 18-24 hours:
| Quality Control Strain | Strain Number | Inoculation Amount (CFU) | Reference or Counting Medium | Method | Quality Control Result | Other Characteristics |
| Salmonella enterica serotype Typhimurium Escherichia coli Pseudomonas aeruginosa |
ATCC14028 ATCC25922 ATCC27853 |
10-100 1000-5000 1000-5000 |
TSA | Semiquantitative | >10 CFU on XLD | Colonies are colorless and translucent, with a black center |
| Escherichia coli | ATCC25922 | 1000-5000 | TSA | Semiquantitative | <100 CFU on TSA | / |
| Enterococcus faecalis | ATCC29212 | 1000-5000 | TSA | Semiquantitative | <100 CFU on TSA | / |
Why Choose Selenite Cystine Broth? Selecting Selenite Cystine Broth ensures you achieve reliable results in your microbiological testing. This medium not only enhances the growth of Salmonella but also minimizes interference from non-target organisms. Its robust formulation allows for the effective screening of food samples, clinical specimens, and environmental sources. visit our [Ready-to-use culture medium] for more related products
