Spontaneous deletion formation within the beta-galactosidase gene of Lactobacillus bulgaricus.

Journal of bacteriology - 1 Oct 1990

Mollet B, Delley M

Abstract excerpt

To investigate the genetic stability of the dairy organism Lactobacillus bulgaricus, we have analyzed 107 spontaneous mutations of the beta-galactosidase gene of this organism. Ten of these mutations were DNA rearrangements giving rise to different deletions, located predominantly within a small hot spot area. The DNA sequences of the different deletion junctions have been determined. The analysis showed that the...
