**4. Conclusions**

The use of the supernatants of *L. plantarum* is a good alternative in the industry of foods to be used as biopreservatives, since these are able to inhibit *S. aureus* during a period of time of 20 weeks when stored at 25 ± 1.0°C; although there is a significant difference between the antimicrobial activity at time 0 and time 20, the antimicrobial activity remains effective.
