PRIORITY: FR 2005-8770 26 Aug 2005. DOCUMENT TYPE: Patent CA Section: 9 (Biochemical Methods) Section cross-reference(s): 10, 16, 17, 61 The invention concerns a compn. for the detn. of Salmonella; the compn. includes a chromogenic substrate for caprylate esterase and a surfactant from the group of nonylphenyl ethoxylates. Thus medium was prepered from (g/L): meat or yeast ext. 3; peptone 5; sodium chloride 5; agar 15; 5-bromo-6-chloro-3-indolyl caprylate 0.2; 5-bromo-4-chloro-3-indolyl-b-glucoside 0.1; sodium deoxycholate1.5; Tergitol NP9 deoxycholate 1.5. The culture medium enabled the differentiation of Salmonella spp. and Salmonella lactose pos. from Escherichia coli. .
