Growth of the PNPT1_Ec strain.

	pnp+	Δpnp	PNPT1Ec
g (min)a	24.7 ± 1.3	32.6 ± 1.7	39.7 ± 3.4
OD600a,b	5.9 ± 0.2	4.0 ± 0.3	2.8 ± 0.2

^aCultures of C-1a (pnp⁺), C-5691 (Δpnp), and C-6001 (Δpnp::PNPT1_Ec) grown with aeration at 37 °C in LD broth. Mean (N = 3) ± standard deviation is reported.

^bOD₆₀₀ reached by the culture after 24 h. All cultures were in stationary phase.
