Lysine Iron Agar (500g) – Product Description

Product Description

Lysine Iron Agar (LIA) is a selective and differential medium used to differentiate Salmonella species and other enteric pathogenic microorganisms based upon their ability to decarboxylate lysine and to produce hydrogen sulphide (H2S). This agar is used frequently in food testing, isolation and enumeration of enteric bacteria and water/wastewater analysis.

Lysine Iron Agar (LIA) is a general-purpose medium that, due to its two important physiological characteristics, can sustain the growth of many enteric group bacteria. It has vast applications in the identification of organisms such as Salmonella, Shigella, and other enteric pathogens through characteristic colour changes and H2S formation in the medium.

Key Features

• **Lysine Decarboxylation**: Distinguishes between the bacteria that can decarboxylate lysine, resulting in an alkaline (purple) colouration within the slant.
  • **Hydrogen Sulphide Production**: The presence of ferrous sulphate in the medium triggers the production of hydrogen sulphide, which forms a black precipitate at the bottom of the medium.
  • **Ideal for Enteric Pathogen Detection**: This medium is suitable for the detection and qualification of various enteric pathogens, including Salmonella, Shigella, and others.
  • **Inhibitor Test and Standardized Media**: Inhibition control, H2S production, and lysine decarboxylation are very consistent, making it reliable in classic biochemical reaction patterns.

Specifications

• **Cat No**: Lysine Iron Agar 500g
  • **Amount**: 500g (Dehydrated powder)
  • **Storage**: Store in a cool, dry place, out of direct sunlight and moisture. Prepared media can be stored at 4°C for short periods of time.
  • **pH**: Neutral-ish, usually about 6.8 ± 0.2
  • **Preparation**: Dissolve in dH2O or deionized water to a final volume of 1L, stirring while boiling to ensure complete dissolution. Then, adjust the volume to 1L. Sterilize by autoclaving at 121°C for 15 minutes.

Applications

• **Clinical Microbiology**: For isolation and identification of enteric pathogens such as Salmonella, Shigella and others from clinical specimens.
  • **Food Testing**: For the food industry to detect enteric pathogens in food products, especially those samples that would be submitted for Salmonella.
  • **Environmental Activity**: Applicable for ecological monitoring, including Salmonella detection in water, soil and food processing environments.
