Description

m–Endo Agar Les is a selective medium recommended for cultivation, isolation and enumeration of total Coliforms from water samples with the membrane filters method (APHA – APAT – ISTISAN). The coliform colonies are red-purple with a characteristic metallic appearance (gold with green reflections). Bacteria that do not ferment lactose such as Salmonella, Shigella e Proteus produce colonies of the same color as the medium. Only colonies with dark red colonies with or without metallic gloss are considered positive.
