Abstract
T. FUJISAWA AND M. MORI. 1996. The β-glucuronidase activity of intact cells of Escherichia coli and Clostridium perfringens was increased in the presence of bile salts. In contrast, bile salts had inhibitory effects on the activity of β-glucuronidase extracted from the lysed cells. These results suggest that the permeability of the bacterial cells is increased by the presence of bile salts, and that bile salts may significantly enhance bacterial β-glucuronidase activity in the intestinal tract.
