Product Description:
SELENITE CYSTINE BROTH
A liquid enrichment used for isolating Salmonella spp from faeces, foods, and other sources in a laboratory setting. Enzymatic Digest of Casein and Animal Tissue supply nitrogenous substances and carbohydrates for bacterial growth. Sodium Phosphate stabilizes pH and reduces toxicity to Selenite. The reducing ability of L-Cystine also lowers the toxicity of this anion. Sodium Selenite inhibits growth of Gram-positive microorganisms such as coliforms and fecal Streptococci. Lactose is the fermentable carbohydrate and maintains an optimal pH by neutralizing the alkalinization occurring upon selenite reduction.
