Influence of polyamine production and proteolytic activities of co-cultivated bacteria on histamine production by Morganiella morganii

In this study, the histamine forming potential of M. morganii (BSS142) is evaluated when it is co-incubated with proteolytic and polyamine forming bacteria. This experiment was designed to examine whether biotic factors such as proteolysis and the presence of other amines influenced histamine forming ability of BSS142. The study showed that the proteolytic activity of Aeromonas hydrophila as well as Pseudomonas aeruginosa greatly enhanced the histamine forming ability of M. morganii. Psychrobacter sangunis, a non proteolytic polyamine producer, negatively influenced histamine production by M. morganii.PMID:35858814 | DOI:10.2323/jgam.2022.04.001
