Lighthart, B. Shaffer, B. 1997. Increased airborne bacterial survival as a function of particle content and size. Aerosol Science and Technology. 27:439-46.

Two test vegetative bacteria, Pseudomonas syringae and Erwinia herbicola, and a physical aerosol decay indicator. Bacillus subtilis var. niger spores, were sprayed into a particle size fractionating wind tunnel. Test bacteria survival significantly increased directly with droplet size for varying test cell to spore ratios and temperature. However survival varied inversely with relative humidity.
