    Definition cell culture growth medium comprising agar, a pH-sensitive dye (phenol red), 1% lactose, 1% sucrose, 0.1% glucose, sodium thiosulfate and ferrous sulfate or ferrous ammonium sulfate Reference Wikipedia, 'TSI slant', http://en.wikipedia.org/wiki/Triple_sugar_iron_agar [13.6.2012]
    Comment All of these ingredients are mixed together and allowed to solidify in a test tube at a slanted angle. The slanted shape of this medium provides an array of surfaces that are either exposed to oxygen-containing air in varying degrees (an aerobic environment) or not exposed to air (an anaerobic environment).Bacteria that ferment any of the three sugars in the medium will produce byproducts. These byproducts are usually acids, which will change the color of the red pH-sensitive dye (phenol red) to a yellow color. Position of the color change distinguishes the acid production associated with glucose fermentation from the acidic byproducts of lactose or sucrose fermentation.
