L cystein brot. Selenite cystine broth is a modification (North and Bar tram, 1953) of the original Leifson (1936) formula, differing only in the addition of L cystine which is considered to enhance Salmonella growth by reduction of toxicity In view of developments in regulatory bodies such as ISO and AOAC this medium is expected to have a limited life. Selenite Cystine Broth contains tryptone as a source of carbon, nitrogen, vitamins and minerals Lactose is the carbohydrate Sodium acid selenite inhibits grampositive bacteria and most enteric gramnegative bacteria except Salmonella LCystine is a reducing agent. 500 ml of cellfree fermentation broth (24 g/l of Lcysteine, 12 g/l of Lcystine, 18 g/l of Nacetylserine) were applied with natural pH (pH 7) to 150 ml of an anion exchange resin (OH − form) commercially available under the name Amberlite® FPA 42C1 from Rohm & Haas The resin was then washed with 250 ml of water (pH 7) and eluted with.
