[Changes in the level of bacitracin synthesis in autolysin-resistant strains of Bacillus licheniformis].


Production of bacitracin by Bac. licheniformis 1001 and its spontaneous autolysin resistant variants was studied. It was found that the antibiotic activity of some variants was 1.5--2 times higher than that of the initial strain. No differences in the activity of serine exoprotease in the initial strain and resistant variants were observed. The latter… (More)
