Abstract |
The purpose of this study was to investigate the inhibitory
effect of antibacterial substances produced by probiotic lactic
acid bacteria (LAB) against biogenic amines-producing bacteria
and the influence of culture conditions on the antibacterial
activity of bacteriocin and organic acid. The bacteriocin solutions
of Lactobacillus plantarum FIL20 (64 AU/ml) and Lactobacillus
paracasei FIL31 (128 AU/ml) showed strong antibacterial
activity against Serratia marcescens CIH09 and Aeromonas
hydrophilia RIH28, respectively. And the lactic acid contents
in the cell-free culture supernatants (CFCS) obtained from
FIL20 and FIL31 strains were 107.3 ± 2.7 mM and 129.5 ± 4.6
mM, respectively. Therefore, the bacteriocin solution (200
AU/ml) and the CFCS (200 μl/ml) produced by L. plantarum
FIL20 and L. paracasei FIL31 significantly (P < 0.05) decreased
the bacterial numbers and histamine and tyramine production
ability of S. marcescens CIH09 and A. hydrophilia RIH28. The
amounts of histamine and tyramine produced by the CIH09
strain under conditions of low initial pH (5.0) and incubation
temperature (15°C) was significantly reduced by treatment
with bacteriocin solution and CFCS obtained from L. plantarum
FIL20. In addition, the bacterial counts and biogenic amines
contents of CIH09 strain were significantly decreased (P <
0.05) when sodium chloride (5%) or potassium nitrite (200
mg/g) were mixed with the antibacterial substances of L.
plantarum FIL20. Consequently, the bacteriocin and organic
acid solution of L. plantarum FIL20 and L. paracasei FIL31
can be used as a biological preservation to effectively control
the production of biogenic amines by the application of hurdle
technology. |
