Health-promoting properties exhibited by Lactobacillus helveticus strains.
Many strains belonging to lactobacilli exert a variety of beneficial health effects in humans and some of the bacteria are regarded as probiotic microorganisms. Adherence and capabilities of colonization by Lactobacillus strains of the intestinal tract is a prerequisite for probiotic strains to exhibit desired functional properties. The analysis conducted here aimed at screening strains of Lact...

2 Department of Food Science, University of Wisconsi nMad ison, WI 53706, USA A prolinase (pepR) gene was cloned from an industrial Lactobacillus helveticus strain (53/7). Three clones, hybridizing with a gene probe specific for a peptidase shown to have activity against diand tripeptides, were detected from a L. helveticus genomic library constructed in Escherichia coli. None of the three clon...

متن کاملGenetic and haplotype diversity among wild-derived mouse inbred strains.
With the completion of the mouse genome sequence, it is possible to define the amount, type, and organization of the genetic variation in this species. Recent reports have provided an overview of the structure of genetic variation among classical laboratory mice. On the other hand, little is known about the structure of genetic variation among wild-derived strains with the exception of the pres...
متن کاملLactobacillus helveticus: the proteolytic system
Lactobacillus helveticus is one of the species of lactic acid bacteria (LAB) most commonly used in the production of fermented milk beverages and some types of hard cheese. The versatile nature of this bacterium is based on its highly efficient proteolytic system consisting of cell-envelope proteinases (CEPs), transport system and intracellular peptidases. Besides use of L. helveticus in cheese...
