^bP = 0.0004 for MA-1 versus NMB values in the exponential phase. 

^cP = 0.1352 for NMB versus NMB ΔgalEt::npt values in the exponential phase. 

^dP = 0.0514 for MA-1 values in the exponential versus the stationary phase. 

^eP = 0.1365 for MA-1 versus MA-1 ΔgalEt::npt values in the stationary phase. 

^fP < 0.0001 for NMB values in the exponential versus the stationary phase. 

^gP = 0.0002 for MA-1 versus NMB values in the stationary phase. 

^hP = 0.009 for NMB versus NMB ΔgalEt::npt values in the stationary phase.
