Selective Enrichment Selenite Cystine Broth for Salmonella

Description

Product Description for Selenite Cystine Broth

Selenite Cystine Broth serves as an essential selective enrichment medium designed specifically for isolating Salmonella from a variety of samples, such as feces, food, and water. This medium plays a crucial role in microbiological testing, ensuring food safety and protecting public health.

The typical formula includes Pancreatic Digest of Casein (5.0 g/L) and Lactose (4.0 g/L), providing vital nutrients that support bacterial growth. Sodium Selenite (4.0 g/L) acts as a selective agent, effectively inhibiting the growth of competing microorganisms. Disodium Phosphate (10.0 g/L) helps maintain pH levels, while L-Cystine (0.01 g/L) further enhances Salmonella recovery. With a final pH of 7.0±0.2 at 25℃, this broth creates optimal growth conditions.

To prepare this effective medium, simply suspend 23.0 g of Selenite Cystine Broth in one liter of distilled or purified water. Heat the mixture to boiling, taking care to avoid overheating. Be sure not to autoclave the broth, as this can compromise its selective properties, essential for isolating Salmonella.

By using Selenite Cystine Broth, laboratories significantly increase their chances of detecting Salmonella in sanitary materials. Its formulation suppresses unwanted microorganisms, allowing Salmonella to thrive. As a result, professionals widely recommend this broth for food safety assessments, clinical diagnostics, and environmental monitoring.

In summary, Selenite Cystine proves invaluable for laboratories focused on microbiological analysis. By choosing this selective enrichment medium, you enhance your ability to detect Salmonella, contributing to overall public health safety. Equip your laboratory with Selenite Cystine, and take a proactive step toward maintaining hygiene and safety standards!
