Klinglers iron agar medium is used to find the enterobacteria which can ferment glucose , lactose and hydrogen Sulphide . They are H₂S producing bacteria .
This media have phenol red as an indicator. When the glucose is fermented to acid , the production of acid turn the indicator from red to yellow, but it is then reoxidised and turns red again .
