Residual antibiotics in milk were identified by high-voltage electrophoresis in 1% agarose gel and bioautographic detection. The test strain Bacillus subtilis EGA was used for the detection, pH of the culture medium was 8.0. An electrophoretic identification map of 13 selected antibiotics has been set up and the following minimal inhibition concentrations (MIC), expressed in mu g per 1 g, have been established: benzylpenicillin 0.06
