Resumen:
Kefir is a fermented milk containing microorganisms showing several
properties beneficial to health. In the present work the safety aspects
and beneficial properties of kefir-isolated Enterococcus strains were investigated for the first time. Enterococcus strains were identified as Enterococcus durans
using phenotypical and molecular characterisation methods. Neither
resistance to clinically important antibiotics, nor genes encoding for
eight different virulence factors were found. Interestingly, selected E. durans
strains were able to inhibit different Gram+ and Gram− pathogens. These
strains were able to survive simulated gastrointestinal conditions and
showed a similar power of adhesion to mucins. Of note, the E. durans
strains possessed anti-inflammatory properties as demonstrated by a
significant inhibition of flagellin-induced response on Caco-2 cells.
Our results indicate that the presence of E. durans in kefir does not represent a threat to consumers' health, and shows their potential both functionality and as probiotics.
