Growth-inhibitory effect of Dtryptophan on Vibrio spp. in shucked and live oysters
Vibrio vulnificus and Vibrio parahaemolyticus are important human pathogens that are frequently transmitted via consumption of contaminated raw oysters. A small amount of D-tryptophan (D-Trp) inhibits some foodborne pathogenic bacteria in high-salt environments. In this study, we aimed to evaluate the antibacterial effect of D-Trp on V. vulnificus and V. parahaemolyticus in culture media, artificial seawater, and shucked and live oysters. The effectiveness of D-Trp in growth inhibition of Vibrio spp. was highly dependent on environmental NaCl concentrations. Higher levels of NaCl (>4.0%) with D-Trp (>20 mM) resulted in higher and more consistent growth inhibition of both Vibrio spp. Treatment with 40 mM D-Trp significantly (P < 0.05) reduced viable V. parahaemolyticus cell counts in tryptic soy broth (TSB) with > 4.0% NaCl at 25C. In contrast, V. vulnificus was more sensitive to D-Trp (20 mM) than V. parahaemolyticus. D-Trp (40 mM) treatment with NaCl (>4.5%) significantly (P < 0.05) inhibited the growth of V. parahaemolyticus and V. vulnificus in shucked oysters immersed in peptone water at 25C throughout a 48-h incubation period. In artificial seawater, D-Trp exhibited a stronger growth-inhibitory effect on V. vulnificus and V. parahaemolyticus at 25C than in TSB at the same level of salinity and inhibited the growth of both V. parahaemolyticus and V. vulnificus in live oysters at 25C for 48 h. Furthermore, we tested the synergistic effect of D-Trp and salinity on the inhibition of total viable bacterial counts (TVC) at refrigeration temperature. D-Trp (40 mM) inhibited the growth of TVC in shucked oysters immersed in artificial seawater at 4C. Therefore, these results revealed that D-Trp will serve as a novel and alternative food preservative to control Vibrio spp. in live oysters at ambient temperature and to extend the shelf-life of shucked oysters at refrigeration temperature. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 153-94-6, and how the biochemistry of the body works.Related Products of 153-94-6
