pH of the culture medium measured before bacterial inoculation (initial) and after the bacterial culture reached logarithmic growth for WT, ΔaraA, and ΔaraE in 1:20 TSB, +0.2% L-arabinose, and +2% L-arabinose.

	Initial	WT	ΔaraA	ΔaraE
1:20 TSB	6.83	6.14	6.14	6.19
+0.2% L-arabinose	6.81	4.69	6.14	6.06
+2% L-arabinose	6.92	4.20	6.09	4.53
