| Research Abstract |
The purpose of this study was to determine the peculiar malodors produced by food-poisoning bacteria, Staphylococcus aureus, and to develop the novel control method for preventing food-poisoning using these malodors. L-leucine(Leu), L-tyrosine(Tyr), and L-methionine(Met) were revealed as the precursors of malodors metabolized by S. aureus. Isovaleric acid, 2-phenypropanoic acid(derived from Leu) and 2-hydroxy-4-methypentanoic acid(derived from Tyr) were identified as the main contributors to the malodors produced by S. aureus. These precursors of malodors had no effect on the bacterial growth and the production of staphylococcal enterotoxin A.
