Over time, the number of both WT B. subtilis Bs916 and ΔgltB mutant cells initially increased and then began to decrease. However, although WT B. subtilis Bs916 could produce normal clusters of cells, the ΔgltB mutant also demonstrated this same trend. By the last time point (i.e., 15 d), there were very few cells in either the WT B. subtilis Bs916 or the ΔgltB mutant, and the clustering of WT B. subtilis Bs916’s had disappeared.
