EPS have been found to enhance
gastrointestinal (GI) colonization of probiotic bacteria in the
GI tract and thus,also play a significant role as prebiotics
(Welman &Maddox,2003).
Many of the LAB strains considered as probiotic are found
to be effective agains tdiverse GI exertions either by adhering
to the gut mucosa,combating pathogens by virtue of producing antimicrobial compounds and/or exerting beneficial
effects on human health (Servin, 2004). Before using bacterial
strains as probiotics,they should be screened for certain
imperative characteristics such as resistance to bile and
low pH,antibiotic susceptibilities and antimicrobial activity
