Abstract

The urease activity of 414 strains representing 21 species of the genus Bifidobacterium was surveyed. The strongest ureolytic strains belong mostly to the species B. suis and only a few to B. breve, B. magnum and "subtile" homology group. The study of some strongly ureolytic strains showed that urea and organic nitrogen concentration did not influence… (More)
