Coliforms are indicator organisms used for assessing the effectiveness of water treatment and disinfection, and for monitoring the sanitary integrity of water and wastewater. They are aerobic or facultative anaerobic, gram-negative, non-spore forming bacteria that can ferment lactose and produce acid and gas.Use m-ENDO Agar LES for cultivation and enumeration of coliform bacteria.
• Selective:Sodium lauryl sulfate and sodium deoxycholate inhibit non-coliforms
• Recommended by the American Public Health Association (APHA) inStandard Methods for the Examination of Water and WastewaterandCompendium of Methods for the Microbiological Examination of Foods^2,3
• Easy-to-read: Coliforms form red colonies with metallic green sheen within 24 hrs when incubated at 35°C.
• Ready-to-use conveience of prepared media.Lactose-fermentation produces acetaldehyde that reacts with the sodium sulfite and basic fuchsin to form red colonies. A metallic green sheen is observed when the organism produces aldehydes with the rapid fermentation of lactose. Nonlactose fermenting colonies are clear, colorless or light pink.On m-Endo LES Agar, coliforms appear as red colonies with a metallic green sheen.This medium contains lactose as the carbohydrate source. Casein peptone and casein-meat polypeptone provide essential nutrients for the growth of bacteria. Yeast extract acts as a growth enhancer and supplies B-complex vitamins. Monopotassium and dipotassium phosphate serve as buffers whereas sodium chloride provides electrolytes and maintains osmotic equilibrium. Sodium lauryl sulfate and sodium deoxycholate are selective agents that inhibit the growth of gram-positive bacteria. Basic fuchsin is the pH indicator. Agar is the solidifying agent.Not all products are available for sale in all territories. Please inquire.Remel™ and Oxoid™ products are now part of the Thermo Scientific brand.
