FIELD: chemistry; biochemistry. ^ SUBSTANCE: present invention pertains to biotechnology and can be used for identifying types of Streptococcus on appearance of three different colour shades of detected microorganisms and fluorescence emission, in addition to changes in the colour of the medium. The selective medium contains specific ratios of mixtures of nutrient bases, rich in natural protein compounds (polypeptides, peptides, protease, amino acids) and vitamins, which allow for heavy growth of the type of interest. The medium also contains a group of inhibitors, a mixture of degradable chromogenic and fluorogenic substances and desaminase activity indictors. ^ EFFECT: identification with high degree of sensitivity and specificity. ^ 7 cl, 3 dwg, 6 tbl, 10 ex
