There are multiple purposes for thiosulfate. A few of these are smelting silver, setting textile dyes, and ceasing bleaching when making paper.
Sodium thiosulfate is reduced to hydrogen sulfide and hydrogen sulfide react with an iron salt yielding typical black iron sulfide.
TSI test used to differentiate the enterobacteriaceae family members like e.coli and enterobacter and pseudomonas

Agar jelly is a type of jelly using the seaweed gelatin know as agar agar as a thickener. Usually it is used in Europe because it does not appeal to the American pallate for the fact that it does not melt in your mouth like gelatin or pectin.
When lactose is replaced with another type of sugar like glucose in the MacConkey Agar, it is usually to identify bacteria mutations. The method to detect the fermentation in a replacement sugar solution is the same as lactose fermented solution.
Agar solidifies media, and will remain solid even when placed in an incubator. Few microorganisms are able to metabolize it, so it won't provide an energy source.
The triple sugar iron agar is a differential medium. The three sugars it contains are:lactose (1%)sucrose (1%)glucose (0.1%)
Agarslant is a means whereby agar is created. It is also known as a TSI or Triple Sugar Iron Test. It is a process whereby agar is cooled in a slanted position. Here's what happens: agar is mixed in a test tube with 1% lactose, 1% sucrose, 0.1% glucose, sodium thiosulfate, and ferrous sulfate or ferrous ammonium sulfate. This causes the agar to react in such a way so that it cools in a slanted position.

triple sugar iron agar is called the multi test because in this test we differentiate the enteric pathogen on the basis of different carbohydrate fermentation i.e glucose,sucrose and lactose.as well as we differentiate on the basis of gas and h2S production....
