Abstract:

Enterococci belong to the lactic acid bacteria (LAB) and they are of importance in foods due to their involvement in food spoilage and fermentations as well as their utilization as probiotics in humans and slaughter animals. The purpose of this study was to evaluate the probiotic properties of Enterococcus faecalis RT 122, RI 6, RI 21 strains isolated from traditional naturally fermented cheese produced in different regions of Iran and Turkey. The ability to autoaggregation and coaggregation are desirable properties for probiotics in health-promoting foods. Therefore, in the current study, we assessed the effect of exopolysaccharides (EPSs) produced by E. faecalis strains on the aggregation and hydrophobicity properties. All E. faecalis strains tested showed auto and coaggregation ability with Salmonella enteritidis ATCC 13076 but the results were strain specific and dependent on exopolysaccharides production. In addition, enterococci strains tested showed affinity to all solvents, suggesting a high complexity of the cell surface. Our results indicate that the ability to autoaggregation, together with cell-surface hydrophobicity and coaggregation abilities with S. enteritidis strain can be used for preliminary screening in order to identify potentially probiotic bacteria suitable for human or animal use.
