Effects of different test media on JK-SH007 biofilm formation. a Images of crystal violet-stained biofilms formed by serial 1, serial 7 and serial 10. Cells were grown in test media for 6 days at 20 °C under static conditions before crystal violet staining. b Quantitative comparison of biofilm formation in serial 1, serial 7 and serial 10. Each experiment was performed at least three times in triplicate. Error bars represent the standard error of the mean. Different lowercase letters represent significant differences (P < 0.05)
