Quantifoil R2/2 grids (200-mesh) (Quantifoil Micro Tools GmbH) were glow-discharged for 60 s at 10 mA.

ETHANE-PROPANE 100 FEI VITROBOT MARK III

Salmonella strain TH16943 (ParaftsZ) was grown aerobically overnight in LB broth from freezer stocks at 37C. After overnight culture, 50 uL of 5% (wt/vol) L-arabinose were added to 5 mL fresh LB broth for each culture, and cultures were incubated for an additional 5 h. To enrich for minicells, 3 mL this culture were spun at 6,000 x g for 5 min, and the supernatant was recovered. The supernatant was spin-concentrated by centrifugation at 18,000 x g for 5 min, and the resultant pellet was resuspended in 50 uL LB broth and was immediately plunge-frozen.
