Product Code TM 1859

  • Description

    Andrade 0.5% lactose peptone water can be used to determine coliforms, particularly Enterobacteriaceae in water and food on the basis of their ability to ferment lactose. Lactose fermentation reaction produces acids which help in differentiation and identification of various bacteria. On metabolism of lactose in the medium, pH of the medium gets lowered due to formation of acid. This causes subsequent colour change of the indicator, from colourless to pink to red. If the carbohydrate is not metabolized, the colour of the medium remains unchanged.
