The presence of inhibitory substances in the dairy industry is an urgent problem. The article presents data from experiments on expanding the spectrum of determination of various groups of antibiotics and the sensitivity of the method for determining inhibitory substances using a test culture of thermophilic streptococcus and indicator resazurin. Various groups of antibacterial substances in the form of veterinary drugs and State standard samples were artificially introduced into milk. In the laboratory series of experiments, the following sensitivity of the method to antibiotics, found in the form of residual concentrations in milk: cephalosporins – 0.01 mg/l; aminoglycosides, fluoroquinolones – 0.001 mg/l; lincosamides, phenols – 0.0001 mg/l. This rapid method remains optimal for the analysis of antibiotics and other inhibitory substances.
