Abstract

SUMMARY

Changes in the amidase, nitrate reductase and phenolphthalein sulphatase activity of were observed following B1-lysogeny. These changes were more consistent in lysogenic derivatives of strains 2 and 14 than in those of strain 10. Strains 2 and 14 appeared to differ from 10 only in that the former possessed a functional salicylamidase locus while the latter did not. Emergence of various phenotypes in the same strain and during the same lysogenic event were observed. Multiple sites of phage integration may have accounted for the variation of 10 (B1) phenotypes.
