Bacterial survival of bacteria associated with feed industry at conditions A) 35% RH and 30°C; B) 85% RH and 12°C. Gram positives included Staphylococcus (n = 3), Corynebacterium (n = 2), Gram negatives included Pantoea (n = 2) and Pseudomonas (n = 2) while Salmonella included isolates of S. Agona (n = 2) and one isolate each of serovars Montevideo, Senftenberg and Typhimurium. Dark bars represent total tested Gram positive strains, gray bars depict Gram negatives, and white bars all tested Salmonella strains. Mean values of triplicate experiments are shown with error bars representing standard error of the mean. Within a group with the same incubation period (0 to 28 days; x-axis), mean values sharing at least one common letter are not significantly different at a P value of < 0.05.
