Abstract: Histamine is mainly produced by microorganisms that are found in fermented foods, and is frequently involved in food poisoning. Two histamine-producing bacteria were isolated from fermented fish products, anchovy sauce, and sand lance sauce by using a histidine decarboxylating medium. The species were identified as Bacillus licheniformis A7 and B. coagulans SL5. Multiplex PCR analysis showed the presence of the conserved histidine decarboxylase (hdc) gene in the chromosome of these bacteria. B. licheniformis A7 and B. coagulans SL5 produced the maximum amount of histamine (22.3±3.5 and 15.1±1.5 mg/L, respectively). As such, they were determined to be potential histamine-producing bacteria among the tested cultures.

Isolation and Characterization of Biogenic Amine-Producing Bacteria in Fermented Soybean Pastes: Jin Seok Moon , Seung Kee Cho , Hwa Young Choi , Ji Eun Kim , So-Young Kim , Kyung-Ju Cho , Nam Soo Han; J.

Abstract: Biogenic amines (BAs) are produced primarily by microorganisms found in fermented foods and are often implicated in food poisoning. BA-producing bacteria found in fermented soybean pastes were isolated and characterized using a decarboxylating medium and multiplex PCR analysis. Two BA-producing bacteria were isolated from traditional soybean pastes: one was a histamine-producing Clostridium strain, and the other was a tyramine-producing Pseudomonas strain. The Clostridium strain was determined to be a potent histamine producer among the cultures tested. Synthesis of tyramine by Pseudomonas sp. T1 was observed for the first time in this study.
