Culture media and detection means for food microbiological analysis

摘要: A selective culture medium for bacterial microbiology analysis comprises a base broth and at least one growth inhibitor selected from brilliant green, nalidixic acid lithium chloride. Preferably there is promoter sodium tetrathionate, ferric ammonium citrate citrate. the inhibitors are present concentrations less than usually used such that 'health' of bacteria to be not compromised. Specifically, media comprising 0.05-0.25 mg per litre green or 1-3 g chloride disclosed. The Salmonella, Shigella Listeria species. promoters concentration greater used. Methods liberation lipopolysaccharides (LPS) using Tween (RTM) affinity detection LPS an antibody core oligosaccharide epitope claimed.
