Influence of Lactobacillus plantarum on Staphylococcus aureus growth in a fresh vegetable model systemThe influence of a Lactobacillus plantarum (B4) on the growth of Staphylococcus aureus (Sa4) was verified by impedometric methods in a suitable model reproducing the characteristics of fresh vegetables. The inoculum size of the single strains and their growth temperature were varied according to a Central Composite Design. The results obtained via statistical analysis showed that the temperature affected the growth of both S. aureus and L. plantarum strains. The pathogenic strain, independently of its inoculum size, was inhibited byL. plantarum at all the tested temperatures. A proper combination of specific lactic acid bacteria and storage temperature should improve the safety of the vegetable products.
