Gelatin Iron Agar 500G

Gelatin Iron Agar is recommended for detecting gelatin liquefaction and hydrogen sulphide production.Gelatin acts as solidifying agent and is the substrate for the organisms producing gelatinase enzyme. Ferrous chloride aids in the detection of hydrogen sulphide indicated by black precipitate. Gelatin is usually liquefied by Clostridium perfringens within 24 to 48 hours and it produces H2S.
