[Inhibitory action of the residues of some new disinfecting agents on the microflora of Bulgarian milk].

Studied were the amounts of residues of disinfection solutions such as antigerm 0.3 per cent, bradophen 0.2 per cent, abosanit 0.35 per cent, trosilin 0.5 per cent, and oxania 2 per cent which could produce inhibitory effects of the microflora of the Bulgarian sour milk. It was established that the presence of more than 25 ml/1 of a given disinfection solution in the milk of the above-mentioned ones at the concentrations cited (with the exception of trosilin) exert a strong inhibitory action on milk microflora and the enzyme processes. As a result no curdling sets in. The use of Bac. stearothermophilus as a test organism can detect but the presence of 150 mg/1 antigerm in the milk.
