Triple sugar iron agar triple sugar iron agar (tsi) is a differential medium that contains lactose, sucrose, a small amount of glucose (dextrose), ferrous sulfate, and the ph indicator phenol red it is used to differentiate enterics based on the ability to reduce sulfur and ferment carbohydrates.

Interpretation of triple sugar iron agar test if lactose (or sucrose) is fermented, a large amount of acid is produced, which turns the phenol red indicator yellow both in butt and in the slant some organisms generate gases , which produces bubbles/cracks on the medium. Triple sugar iron agar (tsi agar) is used for the differentia- tion of gram-negative enteric bacilli based on carbohydrate fermentation and the production of hydrogen sulfide.

Triple sugar iron agar (tsi agar) is used for the differentiation of gram-negative enteric bacilli based on carbohydrate fermenta- tion and the production of hydrogen sulfide. Intended use hardy diagnostics triple sugar iron (tsi) agar is recommended for use in the differentiation of enterobacteriaceae by their ability to ferment glucose, lactose, and sucrose, and their ability to produce hydrogen sulfide. These triple sugar iron (tsi) agar slants contain sucrose, lactose, glucose and iron (ferrous sulfate) lactose and sucrose are both present in tsi in very large amounts (1%.
