Growth of the Bacillus subtilis cell surface.
A double mutant strain, Bacillus subtilis div IV B1 dal trp, has been constructed which grows as filamentous cells and minicells and requires d-alanine for growth. Removal of d-alanine from a growing population of cells resulted in cell bulging 25% of the cell length from one cell pole, followed by cell lysis. Little ultrastructural change in the cell envelope could be detected during bulge formation.
