a
Expression in cultures grown in minimal medium and exposed to 10 mM glutamic acid potassium salt monohydrate, compared to paired cultures grown in minimal medium without glutamate (P < 0.05; n = 4).
b
Expression in cultures grown at pH 5.5 compared to paired cultures grown at pH 7.5 (P < 0.05; n = 4).
c
ND, not determined.
