FIELD: chemistry.
SUBSTANCE: invention relates to field of food industry, biotechnology and deals with antibacterial composition and strain of bacteriophage Escherichia coli, used for obtaining said composition. Characterised composition includes filtrate of Escherichia coli phage lysate, obtained with application of strain of bacteriophage Escherichia coli, deposited in collection of museum of microorganisms of Federal Budget Institution of Science "State Research Centre for Applied Microbiology and Biotechnology" of the Federal Service on Customers' Rights Protection and Human Well-being Surveillance (FBIS SRC AMB of Rospotrebnadzor) under number Ph 64, filtrate of Escherichia coli phage lysate, containing coli bacteriophage, filtrate of staphylococcus phage lysate, filtrate of salmonella phage lysate, filtrate of Listeria monocyctogenes phage lysate and target additives in amount 1.0÷95.0 wt % of composition weight.
EFFECT: claimed composition has required spectrum of specific activity due to inclusion of polyvalent bacteriophage and can be used in production of biologically active additives and food additives.
