Of 53 strains of lactic acid bacteria and Kocuria, screened for production or degradation of biogenic amines, 29 Kocuria varians and four strains of Enterococcus faecalis produced tyramine and, at lower concentrations, histamine. In contrast, Lactobacillus strains that did not possess amino acid decarboxylase activity degraded tyramine. The greatest tyramine oxidase activity was present in the strains L. casei CRL705 (98% degradation) and CRL678 (93%) as well as in L. plantarum CRL681 (69%) and CRL682 (60%).
