Effect of different compatible solutes on desiccation survival of Acinetobacter baumannii. Cultures of A. baumannii were grown overnight and subsequently washed and adjusted to OD 600 2.0 in H2O (○) or 10 mM of the following compatible solutes: trehalose (Δ), glutamate (□), mannitol (▽), glycine betaine (◊). Percent survival in relation to the starting CFU values (2.4 × 105–4.6 × 107 CFU per filter) was determined after 6 and 13 days. For each experiment, mean values of at least four biological replicates are shown. Error bars represent the standard error of the mean (SEM)
