WGS of Bacillus subtilis DK1042 epeAB mutant flare
During prolonged biofilm growth, sporadic outgrowths at the periphery of Bacillus subtilis DK1042 epeAB mutant colonies were observed, and these flares remained stable upon re-streaking, suggesting the emergence of suppressor mutants under severe cannibalism stress. One of these spontaneous mutants was subsequently characterized by whole-genome sequencing of genomic DNA.
