Effect of Growth Media on the Foam Drying Process Recovery of F. tularensis. Formulation 1 (Fr 1) contained 30% (w/v) trehalose and 0.2 wt % Pluronic F68 at pH 6.5, and formulation 2 (Fr 2) further contained 1% (w/v) cysteine and 10 mM potassium phosphate buffer (n = 2 replicates per data point or # of experiment).

Formulation	Growth Media	Foam Drying Process Loss (log10 CFU ± s.d.)
Fr 1	fMHB	2.8 ± 0.6
	fMHB + 250 mM NaCl	2.9 ± 0.0
	fMHB + 29 mM trehalose	3.0 ± 0.2
Fr 2	fMHB	2.3 ± 0.1
	fMHB + 250 mM NaCl	2.8 ± 0.2
	fMHB + 29 mM trehalose	3.0 ± 0.2
