Metabolic patterns of strains starved of P_i for 14 days^a

Strain	OD600	pH	Concn (mM) of:
			Glucose	Pyruvate	Acetate	d-Lactate	Formate
wt	0.84	4.70	10.1 ± 0.2	0.02 ± 0.01	31.4 ± 0.3	0.19 ± 0.01	0.09 ± 0.02
pflB	0.82	4.76	9.7 ± 0.3	0.01 ± 0.01	27.4 ± 0.5	0.13 ± 0.01	0.06 ± 0.01
poxB	0.91	4.76	10.6 ± 0.3	0.88 ± 0.14	13.6 ± 0.1	1.07 ± 0.01	0.11 ± 0.02

^aThe viabilities of wt, pflB, and poxB strains are shown in Fig. 4. On day 14 of incubation, the OD₆₀₀ and the pH of the cultures and the concentrations in the culture supernatants (adjusted to pH 7) of glucose, pyruvate, acetate, d-lactate, and formate were determined. The concentration data are the means ± standard deviations for two independent cultures.
