Did you know?
WebKligler Iron Agar is a differential medium for the identification of enteric bacteria based on the fermentation of dextrose, lactose and H2S production. This medium allows the differentiation of Gram-negative bacilli by their ability to ferment dextrose or lactose, and to produce hydrogen sulfide. WebTiming is less critical when reading H2S results since H2S production is a slower reaction that occurs over a longer period of time. The TSIA/KIA test is a differential medium used …
