Abstract
A urease-deficient derivative of Streptococcus salivarius 57.I was construc ted by allelic exchange at the ureC locus. The wild-type strain was protect ed against acid killing through hydrolysis of physiologically relevant conc entrations of urea, whereas the mutant was not. Also, S. salivarius could u se urea as a source of nitrogen for growth exclusively through a urease-dep endent pathway.
