Abstract

Abstract

In this study the viability of a potentially probiotic Lactobacillus paraplantarum DSM 14485 in the intestinal tract of 22 healthy test subjects was qualitatively assessed in a randomised double blinded cross-over study design lasting 2 x 4 weeks (interventions I and II) with a 4-week washout period. The subjects were given in their diet either spontaneously fermented vegetables (SF) or vegetables fermented by starter bacteria which contained  Lb. paraplantarum DSM 14485 (P). The numbers of lactic acid bacteria (LAB) in fecal samples were at the level of 105 cfu g-1 in both groups. The presence of Lb. paraplantarum DSM 14485 was confirmed by biochemical and molecular methods. We were able to show that Lb. paraplantarum DSM 14485, isolated from spontaneously fermented cucumbers, was viable in the intestine of ten test subjects after taking P-diet when the numbers of LAB were sufficiently high in the product.
