FIELD: biotechnologies.
SUBSTANCE: invention can be used for detection of coliform bacteria and E.coli in specimens of food products and water at performance of bacteriological tests. Feed medium includes a nitrogen source represented by meat peptone or pancreatic hydrolysate of fish flour, sodium chloride, dibasic sodium phosphate, potassium monophosphate, sodium pyruvate, L-tryptophane, sodium dodecyl sulphate, 6-chloro-3-indolyl-β-D-galactopyranoside (Salmon - GAL), 5-bromine-4-chloro-3-indolyl-β-D-glucoronide-(X-GLUC), isopropyl- β-D1-tiogalactopyranoside (IPTG) and microbiological agar in the specified ratio.
EFFECT: invention allows reducing identification time, improving difernetiation accuracy of coliform bacteria and Ecoli, and simplifying a feed medium preparation method.
