1 Data are from three independent triplicates and presented as mean ± standard deviation. Means within the same column denoted by the different letters are significantly (p < 0.05) different by Duncan’s multiple range test. The order was sorted in alphabetical order. 2 Ss: Streptomycin sulfate, 3 Oa: Oxolinic acid, 4 Sr-Pcc: streptomycin-resistant P. carotovorum subsp. carotovorum.
