For what bacteria would you use the TSI test
Homework Answers
Ans. Triple sugar iron (TSI) medium consists of three sugars (glucose, lactose and sucrose), sulphur in from of ferrous sulfate, sodium thiosulfate, and phenol red as indicator.
The bacteria which can ferment any of these sugars cause change of the color of the medium. Sulphur reduction by bacteria is exhibited blackening of the medium.
# It is used as differential medium for identification of enteric bacteria including Enterobactor, Salmonella, Shigella, etc.

Questions
Experiment 2: TSI The triple sugar iron agar (TSI) can identify gram negative bacteria based on how they metabolize carbohydrates. It contains three carbohydrates-glucose, lactose and sucrose, in addition to sodium thiosulfate which some bacteria use in the production of hydrogen sulfide (H2S). It also contains iron in the ferrous form and phenol red as a pH indicator. TSI is poured into a tube when heated to a liquid form, and the tube is slanted as...
