Abstract: The present disclosure relates to a culture medium for cultivation and identification of bacteria of genus Pectinatus, which includes at least one source of carbon, at least one source of nitrogen, at least one source of amino-acids, at least one source of vitamins, at least one source of sulphur, at least one source of biogenous metals, at least one substance reducing redox potential and a buffer component, whose principle consists in that, it further comprises iso-?-acids and/or their reduced hydrogenated derivatives in concentration of 10 to 80 mg/l. The disclosure further relates to a method for taking swab samples using swabs with sampling head, whose principle consists in that, before taking swab sample the sampling head of the swab is dipped into the solution of sterilised distilled water with addition of substance reducing the redox potential in concentration of 0.25 to 3 g/l, and once the swab sample is taken, it is positioned into the culture medium according to the disclosure.
