Gissa's medium with arabinose is used for the differentiation of microorganisms on the ability to ferment sugars and alcohols. The medium indicator, bromocresol purple, during fermentation of the carbohydrate (alcohol) and acid secretion changes color from purple to yellow, which indicates the ability of bacteria to ferment the carbohydrate (alcohol). The semi-solid medium, seeding method is "pricking" a microbiological loop. The tubes are incubated at 37 ° C for 24 hours, then evaluate the color change.

Purpose: Differentiation of microorganisms by the ability to ferment carbohydrates
