Survival and recovery of S. meliloti cells after drying and rewetting. (A) Survival (CFU) of S. meliloti strains 1021, 102F84, and 102F85 in PMM, dried on nitrocellulose filters and stored at 22% relative humidity (RH) for three days (n = 45, 18, 18, respectively). (B) Survival (CFU) of S. meliloti 1021 on nitrocellulose filters, Ottawa sand, or alfalfa seeds. Cells were stored at either 100% (black bar) or 22% RH (white bar) for five days (n = 6). (C) Survival (CFU, white bar) and cell recovery (direct counts, black bar) of cells using a nitrocellulose filter over seven days (n = 6). (D) Quantitative recovery of cells (direct count) after three days of storage under 100% or 22% RH on nitrocellulose filters (white bar = cristal violet, light grey bar = Live/dead, dark grey bar = %red, black bar = %green). In all graphs the error bars represent the SEM.
