Thermo Scientific™ Jordans Tartrate Agar (5mL Butt)

Description

• Differentiate Enterobacteriaceae based on tartrate utilization using Thermo Scientific™ Remel™ Jordans Tartrate Agar
• In 1928, Jordan and Harmon developed a medium to detect sodium tartrate fermentation by certain strains of Salmonella 1
• In 1957, Ellis et al
• demonstrated that to differentiate Salmonella and Arizona , organic acids such as D-tartrate were useful 2
• This agar medium differentiates Enterobacteriaceae based on tartrate utilization
• This medium contains peptones that supply nitrogenous compounds and amino acids necessary for the growth of enteric gram-negative bacilli
• Ready to use – Convenience of prepared media
• Differential media - Sodium tartrate is a differential agent which is fermented by some enteric gram-negative bacilli Easy to interpret - Positive test - Yellow color development in the lower portion of the tube; the surface zone remains red Negative test - No color change; agar remains alkaline with a red color throughout the tube Sodium chloride is a source of essential electrolytes and maintains osmotic equilibrium
• The acid produced results in a pH change causing the phenol indicator to change from red to yellow in the lower portion of the tube.
