5. Conclusions
Based on the knowledge of the beneficial effects of GABA and
the many studies that confirm this, this paper reports the high
capacity of gamma-aminobutyric acid production of ten strains
isolated from artisan Spanish cheeses. The results showed the high
GABA-producing ability of the L. brevis strains, CECT 8183, CECT
8181, CECT 8182 and L. lactis ssp lactis CECT 8184, under nonoptimized
conditions, opening new ways of research to optimize
the production of GABA and the possibility of creating co-cultures
with these strains. Furthermore, the findings of this study make it
possible to use these strains in the bakery industry to obtain healthpromoting
bakery foods that are rich in GABA.
To determine the free amino acid profile of the homemade
Spanish cheeses with particular relevance on GABA content will be
the perspective futures for this study in order to establish any
correlation among amino acid concentration and the amount of
lactic acid bacteria which could indicate specific microbial activity
