Involvement of rocG in elevated pH and ammonia levels in the growth medium of strain 1A95 (degU32). (A) Growth curves of B. subtilis strains 168 (closed squares) and TM013 (rocG::cat, closed diamonds) in the soytone–glucose medium; pH values are indicated for 168 (open squares) and TM013 (open diamonds) cultures. (B) Growth curves of strains 1A95 (degU32, closed squares) and TM014 (degU32 rocG::cat, closed diamonds) in the soytone–glucose medium; pH values are indicated for 1A95 (open squares) and TM014 (open diamonds) cultures. (C) Levels of ammonia in media at 12 (gray bars) and 24 (black bars) h after inoculation.
