ABSTRACT:
The present invention relates to a microbioligcal test method for detecting antibacterial compounds in liquid samples such as milk, meat juice, serum and urine. The method employs an acid-base or redox indicator to detect growth of a test organism and is characterised in that a thermophilic strain ofBacillusorStreptococcus, e.g.Bacillus stearothermophilusvar.calidolactisC953, is employed at a concentration of above 107CFU/ml, preferably between 2×107and 3×108CFU/ml.
