Conference Abstract Book

The important points; • The CFSs resulted in strong decreases in cadaverine and putrescine and agmatine production by E. coli and S. Paratyphi A , although remarkable increases were observed for histamine, spermidine, spermine, serotonin, dopamine (except for S. paratyphi A ) and tyramine in the presence of CFSs of LAB in lysine decarboxylase broth. • Inhibition of CAD production was observed all of CFS of LAB strains. • Most of all CFS of LAB strains revealed statistically inhibitor effect because of weak organic acids. • Lactic acid slowed down microbial growth, reduced pH quickly and lessened the production of AMN and BAs. • Consequently, in order to prevent the formation of high content of BAs by bacteria in fermented food, it is advisable to use CFS for food and food products in the food industry.
