FIG. 5.

Levels of β-galactosidase from an exoA-lacZ translational fusion during growth and sporulation of (A) wild-type and (B) sigG strains. B. subtilis strains (A) PERM504 (exoA-lacZ wild type) and (B) PERM527 (exoA-lacZ sigG) were grown and sporulated in liquid DSM. Cell samples were collected at different times and treated with lysozyme, and the extracts were assayed for β-galactosidase as described in Materials and Methods. Shown are β-galactosidase specific activities in (▴) wild-type and (▪) sigG strains and (•) A₆₀₀.
