Fig. 2From: Biochemical and molecular changes of the zosteric acid-treated Escherichia coli biofilm on a mineral surfaceE. coli biofilm formation being monitored through the changes in a the amide II and b polysaccharide band area, without and with ZA. Dashed vertical line indicates the initiation of the dynamic condition with a flow rate of 0.8 mL/min. c, d) The ratios of the integrated intensities of bands corresponding to the proteins (AmII, 1546 cm–1), the nucleic acids, (NA, 1234 cm–1), and the polysaccharides (PS, 1080 cm–1)Back to article page
