Three groups of samples were used for this analysis: E. coli challenged with 25, 50 or 75 μg/ml of Gentamicin Sulfate, each group having four replicates cultured in space and four on Earth (with the exception of Space and Earth 50 μg/ml, and Space 75 μg/ml, which had n = 3). A Welch’s test showed that there was a 13-fold increase in overall final cell count in space with respect to ground (Welch’s F(1, 10.88) = 116.68, p
