Abstract

A lactic acid bacteria Leuconostoc paramesenteroides was isolated and characterized from cheddar cheese and was adapted to grow at low pH (2.0) and high bile salt concentration (2%) by sequential sub-culturing so that it can survive the extreme environmental condition of gut. Cell hydrophobicity assay shows the maximum adherence of the culture to toluene (46.11%). Adhesion ability was confirmed by in vitro assay using rat intestinal epithelial layer. The culture has an antimicrobial activity against food borne pathogens and is vancomycin sensitive. The culture shows a b-galactosidase activity of 3.42 lM/ mg protein, which indicates the ability of the culture to hydrolyze lactose for easy absorption. All these properties determine the ability of the culture to be used as a probiotic. Keywords
