Activation of intact bacteria and bacterial fragments mixed with agar as cloud droplets and ice crystals in cloud chamber experiments

"Experiments were carried out at the Karlsruhe Institute of Technology's Atmosphere cloud chamber, injectingbacteria-containing aerosol samples into the cloud chamber and inducing cloud formation by expansion over a temperature range of -5 to -12 °C. " cloud droplets and ice crystals were sampled by a pumped counterflowvirtual impactor inlet. Results from three expansions of two bacterial strains show that the cloud dropletresiduals had nearly the same size distribution as the smaller particles mold mode and had mass spectra that closely matched those of bacterialfragments mixed with agar. "It's analysis of ice residuals that were sampled through an ice-selecting PCVI also shows that the same particles that caused cloud droplets, bacteria fragments mixed with agar, were the only particle type found in ice residuals. ".
