Selenite Cystine Enrichment Broth Selenite Cystine Broth , 100g

Description: 

Selenite Cystine Broth Base is modified from the formula of Leifson 2 with added cystine3. This addition has given favourable results in many studies4. Liefson2 suggested that it is best to tube the medium to a depth of 2 inches (50mm) or more. 

The effect of the cystine may be due to its reducing abilities which will lower the toxicity of selenite to micro-organisms and/or the extra organic sulphur provided may have a sparing effect on the critical sulphur components of the bacteria, again reducing the selective effect of the se lenite. 

Selenite Cystine Broth is used for enrichment culture of salmonellae from faeces, foodstuffs and other materials. The formulation corresponds to that recommended by the AOAC 5 for detection of Salmonella in foodstuffs. It is included among the standard methods media of the American Public Health Association 6,7. It also complies with the requirements of the United States Pharmacopoeia8.
