WebLysine Iron Agar is used for the differentiation of microorganisms on the basis of lysine decarboxylase and hydrogen sulfide production. Neogen® will conduct a physical inventory at the Lansing location on Friday, April 21, 2024. Any food safety orders received after 3 p.m. ET, Monday, April 20, 2024 will be processed on Monday, April 24, 2024 WebLysine is the decarboxylase substrate. Sodium thiosulfate and ferric ammonium serve as indicators of hydrogen sulphide production under alkaline conditions. Phenol red is the pH indicator. Sodium deoxycholate is the selective agent inhibiting most Gram-positive bacteria. Agar is the solidifying agent. PREPARATION

WebAgar is the solidifying agent. Fermentation of dextrose leads to the production of acid, which changes the indicator from red to yellow. As there is little sugar, i.e. dextrose, the production of acid is very limited and therefore a reoxidation of the indicator is produced on the surface of the medium, and the indicator remains red.
